VirtualBox -- professional, flexible, open : Interesting solution for many problems !!

VirtualBox is a general-purpose full virtualizer for x86 hardware. Targeted at server, desktop and embedded use, it is now the only professional-quality virtualization solution that is also Open Source Software.
Some of the features of VirtualBox are:
  • Modularity. VirtualBox has an extremely modular design with well-defined internal programming interfaces and a client/server design. This makes it easy to control it from several interfaces at once: for example, you can start a virtual machine in a typical virtual machine GUI and then control that machine from the command line, or possibly remotely. VirtualBox also comes with a full Software Development Kit: even though it is Open Source Software, you don't have to hack the source to write a new interface for VirtualBox.
  • Virtual machine descriptions in XML. The configuration settings of virtual machines are stored entirely in XML and are independent of the local machines. Virtual machine definitions can therefore easily be ported to other computers.
  • Guest Additions for Windows, Linux and Solaris. VirtualBox has special software that can be installed inside Windows, Linux and Solaris virtual machines to improve performance and make integration much more seamless. Among the features provided by these Guest Additions are mouse pointer integration and arbitrary screen solutions (e.g. by resizing the guest window). There are also guest additions for OS/2 with somewhat reduced functionality.
  • Shared folders. Like many other virtualization solutions, for easy data exchange between hosts and guests, VirtualBox allows for declaring certain host directories as "shared folders", which can then be accessed from within virtual machines.
A number of extra features are available with the full VirtualBox release only (see the "Editions" page for details):
  • Virtual USB Controllers. VirtualBox implements a virtual USB controller and allows you to connect arbitrary USB devices to your virtual machines without having to install device specific drivers on the host.
  • Remote Desktop Protocol. Unlike any other virtualization software, VirtualBox fully supports the standard Remote Desktop Protocol (RDP). A virtual machine can act as an RDP server, allowing you to "run" the virtual machine remotely on some thin client that merely displays the RDP data.
  • USB over RDP. With this unique feature, a virtual machine that acts as an RDP server can still access arbitrary USB devices that are connected on the RDP client. This way, a powerful server machine can virtualize a lot of thin clients that merely need to display RDP data and have USB devices plugged in. 

Download VirtualBox

Here, you will find links to VirtualBox binaries and its source code.

VirtualBox binarie

The binaries in this section are all released under the VirtualBox Personal Use and Evaluation License (PUEL). By downloading, you agree to the terms and conditions of that license.
  • VirtualBox 3.1.6 for Windows hosts x86/amd64
  • VirtualBox 3.1.6 for OS X hosts Intel Macs
    Due to an accident the original 3.1.6 Mac OS X package (build 59338) was broken. Please install the fixed package if you installed the broken package. Sorry for the inconveniences!

After getting the sources in one of the ways listed above, you should have a look at the build instructions.


End-user documentation

This page is for end users who are looking for information about how to download and run VirtualBox.
In order to run VirtualBox on your machine, you need:
  • Reasonably powerful x86 hardware. Any recent Intel or AMD processor should do.
  • Memory. Depending on what guest operating systems you want to run, you will need at least 512 MB of RAM (but probably more, and the more the better). Basically, you will need whatever your host operating system needs to run comfortably, plus the amount that the guest operating system needs. So, if you want to run Windows XP on Windows XP, you probably won't enjoy the experience much with less than 1 GB of RAM. If you want to try out Windows Vista in a guest, it will refuse to install if it is given less than 512 MB RAM, so you'll need that for the guest alone, plus the memory your operating system normally needs.
  • Hard disk space. While VirtualBox itself is very lean (a typical installation will only need about 30 MB of hard disk space), the virtual machines will require fairly huge files on disk to represent their own hard disk storage. So, to install Windows XP, for example, you will need a file that will easily grow to several GB in size.
  • A supported host operating system. Presently, we support Windows (primarily XP) and many Linux distributions on 32-bit hosts and on 64-bit hosts. Support for Mac OS X and Solaris and OpenSolaris appeared in 1.6.
  • A supported guest operating system. Besides the user manual (see below), up-to-date information is available at "Status: Guest OSes".

5 Reasons why Ubuntu 9.10 is better than Windows 7

1) Security
Windows 7 is no more secure than Windows has ever been. Is it better than Vista? Sure. Is it faster than XP? Not so much. Does it run a ton of popular applications? You betcha. But is Windows 7 still prone to an endless array of malware programs and stuck with a pre-Internet security model? Yes — yes, it is.
I'm able to keep a Windows PC safe. I run my own Windows PCs and servers and help with friends. While I'm good at computers, I'm sure anyone who's reasonably smart can manage it as well. But I'm lazy: I don't want to always be keeping my eye on Windows threats; I don't want to worry about being hacked while shopping online; and I don't want to be careful about avoiding clicking on a crooked link in yet another malicious e-mail letter.
With Linux, I can be lazy and safe.
2) Cheap
I'm also cheap. I use older computers until they fall apart. I have Ubuntu 9.10 working great on a 1.4GHz Pentium IV HP with 512MB of RAM — a machine I got back in 2000. I could no more get a decent version of Windows 7 (Home Premium or above) to run on that box than I could get my old Toyota RAV-4 to break 100 MPH on the highway.
But forget about the hardware: let's talk upgrade prices. You can get Windows 7 now quite cheaply. For example, Windows 7 Home Premium lists for $119.99 as an upgrade, but you can do a clean install for the same price. With some shopping around, you can easily get that version of Windows 7 for around $50. Compare that to Ubuntu, where the price is... uh... zero.
3) Easy upgrade
This is how I upgraded Ubuntu: I downloaded and burned a CD, booted up my Ubuntu system with it, and installed the new version. I was done. Total time, just short of an hour.
This link describes how I upgraded my XP PCs to Windows 7. It took me eight hours. Here's the short version: I had to use two additional programs — Windows Easy Transfer and LapLink's PCmover — besides my installation DVD. When I do this for a business, I replace Windows Easy Transfer with User State Migration Tool 4.0.
It isn't easy. Unless you love playing with technology for its own sake, don't do it. If you really want Windows 7, and you're currently using XP, buy a new Windows 7 PC. It's not only easier, but when you consider how much time the process takes, it's also cheaper.
The upgrade path from Vista is much easier, but it's still time-consuming: Microsoft itself estimates that it can take up to 20 hours.
4) Hardware compatibility
There is a persistent delusion that Linux only supports a limited set of peripherals. Wrong. Ubuntu Linux supports pretty much every piece of hardware out there. Yes, there are some items, especially graphic cards and chipsets, for which you may need to download a driver to get the most out of your graphics.
What does this have to do with comparing Windows 7 and Ubuntu? A lot. Even though Microsoft did a much better job of supporting hardware with Windows then they did with Vista, it still has gaps in supporting commonplace devices.
For example, there's the already infamous iPhone synchronization problem, which seems to be a combination of 64-bit Windows 7 and certain high-end motherboards that use Intel's P55 Express chipset. Or how about this one, which I find hard to believe but it's true: many HP printers still don't have Windows 7 drivers.
How can this be!? The last time I checked with IDC, HP still had 54% of the U.S. printer market. Amazing. Simply amazing.
5) Applications
Conventional wisdom is that Windows has the software advantage because it has more polished applications than Linux does. And it does. But how many of those do you use? Sure, if nothing but Adobe Photoshop will do, then you're not going to want to run Linux. Of course, my question to you then is why aren't you running Snow Leopard on a Mac — but that's neither here nor there.
But, with the exception of games, I don't see any reason to favor Windows. Ubuntu Linux comes with a free office suite, OpenOffice. If you want an office suite for Windows 7, you're going to be paying extra for it. Want an e-mail program? Outlook Express doesn't come with Windows anymore. Ubuntu has Evolution, the best e-mail and groupware client on the planet as far as I'm concerned. Need to back up your system? Both can do that, but only Ubuntu has its own online back-up service, Ubuntu One, with 2GB of storage.
Want a program that doesn't come with the operating system? Easy. Use the Ubuntu Software Center, Ubuntu's new one stop application "store." I put store in quotes because it's all free. With Windows, you know the drill. Go to your local store, poke around what's available on Download.com and Tucows, etc. etc. Just be sure to have your credit card ready since a good deal of Windows software isn't open source or free.
I don't expect really to convince any Windows fans out there to switch. What I do hope for though is to give you some food for thought. Give Ubuntu a try; there are many easy ways to try Linux without changing anything on your Windows PC. You may just fine that Ubuntu or another desktop Linux will do everything you want to do on a computer with a lot less trouble and money.

For those of you who think that Linux is terrible and Windows rocks, here is my say on why Ubuntu is better than Windows.
  1. No Viruses - Thats true! as Linux does not recognize Win32 Executables so the possibility of having a virus on-board is absolutely 0%
  2. Open Source - Unlike Windows, Linux distributions are open source and the source code can be edited and modified to the most to suit your needs.
  3. Better Learning - While Windows just teaches you how to install and run a program, Linux helps you do that using a Terminal. So if you fall in a situation where you don't have a GUI, you can operate things well.
  4. Free Software - Every application and software on Linux is free and open source. You don't need to worry about licenses anymore and you can always find a better and free Linux alternative to a Windows application.
  5. Easy to Use - This point may seem ironic but is true to a lot of extent. Linux Ubuntu is one of the most user-friendly and easy to use Linux distribution which even beats Windows XP and Vista in usability and ease of use.
  6. Ubuntu Community Help - Ubuntu has a very active support and help community where you can get answer to your questions and problems in minutes.
  7. Cool Desktop Effects - For those who think Aero in Windows Vista is damn cool! wait till you experience Compiz on Ubuntu which provides better 3D desktop effects with less resource usage.
  8. Easy Upgrade - You can upgrade Linux Ubuntu through the package manager and all applications can be installed/updated through it. There is no need to Google for freewares as the package manager helps you find all of them.
  9. Highly Customizable - If you like customizing your operating system without a billion registry and software hacks then Ubuntu is your ultimate choice.
  10. Experience Live - Linux Ubuntu CDs come with a pre-installed OS environment which allows you to run the OS without even installing it. Carry your Ubuntu Live CD with you and use it on any PC anywhere around the world.

How to stop Windows 7 reboot loop -: Little Trick !!

 
We know pretty well that Windows 7 is a quite new operating system which is still in its RC version and therefore not ready (at the time writing)  for the market and regular not-savvy users. That’s why we should not be surprise if, every now and then it reboots automatically to prevent the computer from being damaged beyond recovery. Such a behaviour is preset by Microsoft and it is triggered upon system failure. Anyway, if you are not a lucky person your Windows 7 may become stuck and therefore enters in a infinite reboot loop, an endless series of  turn-off and turn-on loops without any apparent way to get out of it. Let’s s lean how to stop Windows 7 reboot loop thanks to a little trick!
  1. When your computer starts its next reboot (black screen), just hit F8 on your keyboard a lot of times till you get the Advanced Boot Options screen.
  2. Now, with your arrow keys, select Disable automatic restart on system failure and press Enter.
  3. Well, done!

How To fix Vista Problem With "USB Device Not Recognized"


I’ve had the dreaded Windows Vista for exactly a year now and I just had my first real “issue” with the OS. It was the dreaded Windows Vista “USB Device Not Recognized” error that seemed to appear after a quick power blip in my home.
For those of you not familiar with the famous Windows Vista USB Device Not Recognized error, I’ll give you a quick synopsis: you are using Windows Vista and minding your own business when suddenly a little pop-up message appears and tell you, surprise! you have a “USB Device Not Recognized!” There’s an annoying little bell that rings and you click on the stupid pop-up bubble and get.. well… nothing.
At least for me I saw nothing. And here’s the problem: you can’t find anything wrong so you can’t actually fix anything. Windows Vista doesn’t tell you which USB device is not recognized, which USB port has the problem or what it thinks is happening. The error message “USB Device Not Recognized” is just about completely meaningless. But every 30 seconds the bubble pops up again with that annoying little bell.

So I did what I do whenever I hear a discouraging sound coming from my car engine: I turned up the volume on my iTunes and promptly forgot about the message. Eventually I got smart and just turned the Windows Alert sound off.
After a few days the error was still popping up and though I couldn’t hear the bell, the bubble was troubling me. Other people have spent hours searching through documentation and reloading Windows Vista from scratch and downloading USB drivers. I am far too lazy to do that anymore, so I just went searching on the internet for the stupidest most implausibly easy solution I could find.
And it worked.


The solution is simple:

1. Unplug (not just turn off) you PC.
2. Unplug all your USB devices from your PC (and, heck, any power supplies as well)
3. Wait 30 minutes or more.
4. Plug in your essential USB devices (keyboard, mouse).
5. Plug in your PC, turn it on.
6. Pop in the rest of your USB devices.

Ta-da, your Windows Vista USB Device Not Recognized Error is solved. This worked for me. I actually did it once without unplugging the USB devices and the problem went away for about three days and then appeared again. I did it again, taking out all my USB devices and I’ve been going for a couple weeks now with no problem.

The Official Windows 7 Guide

What is this guide for?

This step-by-step tutorial will help you getting Microsoft Windows 7 for free and safely. You'll learn how to install Windows 7 and how to activate it using the safest and most reliable method currently available.


The philosophy behind the guide

The philosophy behind this guide is to promote universal access to knowledge for every human being. Although it is mainly about proprietary Windows, free software is being slightly introduced in this guide (BitTorrent client, hash calculator, open source loader etc.).



Part 1 of 4: Download Windows 7

The fastest way to download Windows 7 is using BitTorrent, which is a P2P protocol that allows file sharing. Not only BitTorrent provides high speed of download for popular files, but it also gives you the opportunity to help other people by making their download faster.

To download files using BitTorrent you need an application that supports BitTorrent protocol. You might use
Tribler (Windows, Macintosh OS and Linux) or Transmission (Macintosh OS and Linux only), they are both free and open source software. Feel free to use any other BitTorrent client.

Once you have a BitTorrent client, download the tiny ".torrent" file bellow that belong to the version that you want (32 bits or 64 bits). This file will be directly opened with your BitTorrent client and the download will start instantly.

Torrent Links:

Those 2 ISOs above allow you to have Windows in any language that you want (35 languages available).
› Take a look at section 5-F to select your language.

These ISOs also allow you to install any edition that you want (Ultimate, Professional, Home Premium, Home Basic, Starter).
› Take a look at section 5-G to quickly unlock other editions.

Note: By default it will install the Ultimate edition.
Note: Multi-language is available only if you install the Ultimate edition.




Part 2 of 4: Check the authenticity

It is absolutely crucial that you check the authenticity of the ISO you just downloaded. You must check that it hasn't been modified by anyone, that it's clean from spy wares and viruses, and that it is free from corruption or any transfer error.

To confirm the authenticity of the ISO you downloaded, all you have to do is to make sure that it is exactly (bit for bit) the same as the one Microsoft provides. We can know that two files are identical by matching their hashes. The hash of a file is the result of its calculation. Each file has a unique hash, if the file is modified (even only by 1 bit) then its hash will be completely different.

Microsoft provides through his website (http://blogs.technet.com/[...] and http://technet.microsoft.com/[...]) the official hashes for all the Windows 7 ISOs. Please check the hash of the ISO that you have downloaded using HashCheck (direct downloadinstructions) or any other hash calculator, and verify that it is the same as the ones provided by Microsoft:
  • Microsoft Windows 7 32 Bits
    • MD5: D0B8B407E8A3D4B75EE9C10147266B89
    • SHA-1: 5395DC4B38F7BDB1E005FF414DEEDFDB16DBF610
  • Microsoft Windows 7 64 Bits
    • MD5: F43D22E4FB07BF617D573ACD8785C028
    • SHA-1: 326327CC2FF9F05379F5058C41BE6BC5E004BAA7



Part 3 of 4: Install Windows 7

You have 2 options to install Windows 7. You can simply burn the ISO to a DVD (Scroogle: How to burn an ISO to a DVD), or you can install Windows 7 from a USB flash drive instead of a DVD.

Insert the Windows 7 installation disk into your drive and restart your computer. Press any key when asked to launch the installation (Scroogle: How to boot from a DVD). You might need to change the boot priority in your BIOS in order to boot from your DVD drive or from your USB flash drive (Scroogle: Change boot priority order).

During the installation, you do not need to enter any product key, just bypass the step when it asks for one. You might also uncheck the box "activate online".



Part 4 of 4: Activate Windows 7

The safest method to activate Windows 7 is using a software called a "loader". It is safe because whatever happen this is only software so even if it doesn't work you will be able to uninstall it and continue to use your computer.

It is also the most reliable software method available today. This method has been working for Windows Vista for more than 3 years (and counting) and has proven its reliability and efficiency. This is a mature technology to activate Windows, it works with Windows 7 32 and 64 bits on any computer (homemade or branded) and even on Macintosh. Nothing special is required before using a loader.

You're invited to download and install the Windows 7 Loader created by Daz, which is currently the most popular loader. However if you want to try another one, there are other loaders (including open-source ones), just take a look at section 6-K.

Note: In very specific cases, it might happen that the default mode won't work if you have an unusual configuration, and in very rare cases, might even prevent Windows from starting.

Don't worry! Just press Escape or the "R" key during start up until you see the loader's menu, then select "Windows without loader" and press ENTER. Once on Windows, just re-install the loader using another mode.
Once done, you might want to check the activation status: In the Start menu, make a right-click on Computer then select Properties. Scroll down and check the activation status at the bottom. If you want to display more details about the activation status take a look at section 6-E.

5. Frequently Asked Questions


A. Which is the final version of Windows 7? I want the latest version!
During its development, Windows 7 was available to the public as a Beta, and later as a RC (Release Candidate). The development of Windows 7 ended on July 13, 2009. Since this date, the final Windows 7 was available through many distribution channels: First through Piracy since July 13, then through MSDN/Technet since August 06, and finally through Retail distribution since October 22.

There is only one final version of Windows 7, it was compiled on July 13, and was never modified since this date. The ISOs that first leaked on July 13 through Piracy are the same that was available later through MSDN, and are also the same as the ones available through resellers since October 22.

This final version is called RTM (Release to Manufacturing). Microsoft's policy is to not touch this version until a Service Pack is released, which usually comes one year after the RTM was released.

B. Did or will Microsoft blacklist the keys we use for activation?
No. Microsoft technically cannot block OEM SLP keys, first because it's an offline activation, and second because those keys are used by tens of thousands of legitimate users.

OEM SLP keys are used by OEM manufacturers to mass-activate any computer they sell with Windows pre-installed. Technically for the activation to work using an OEM SLP key, Windows checks if the computer is OEM manufactured. This is done by checking if there is appropriate SLIC table in memory when Windows starts, and that the certificate (a simple file) installed on Windows is matching the SLIC. Putting this SLIC table in memory before Windows starts is what loaders are all about.

C. Can I turn ON automatic Windows Updates?
Yes. The method to activate Windows described in this guide (i.e. using a software called a "loader") imply that your Windows is acting exactly as it would act if it would be a legal copy. You can safely use Windows Update, download software from Microsoft.com and run any genuine check confidently.

D. Which edition of Windows 7 can I activate?
All of them, except the N editions, for which we don't have OEM SLP keys.

E. Can I upgrade from Windows 7 Beta or RC to the final Windows 7 RTM?
No. You can however bypass this restriction by editing the build number (put 6000) in the file "sources/cversion.ini" which is in the ISO of Windows 7, before burning it. — This is strongly not recommended, make a fresh install instead.

F. How to switch my Windows to another language?
Windows 7 Ultimate includes a simple option to choose the display language. It will change the language of your Windows as easy as a click, without even the need to restart your computer! All 35 languages are available.
  1. Once you have downloaded and installed Windows 7 Ultimate, go to Windows Update (type "wup" in Start menu).
  2. Check for updates and show the optional updates.
  3. Download and install any language that you would like.
  4. Once the language pack you want is installed, type "change display language" in Start menu and press ENTER.
  5. Select your language and click OK!
This was only for your User Account. If you also want to apply your language to the Welcome Screen, and make it the default language for other accounts, continue with the steps below:
  1. Type "change display language" in Start menu and press ENTER.
  2. Select the "Administrative" tab, and click the "Copy settings..." button.
  3. Select and tick the 2 checkboxes and click OK!

G. How to unlock the other editions of Windows?
All the editions of Windows are included in the ISO image available to download in this guide. To be able to select the edition you want during the installation, you just need to delete the file "ei.cfg" that is in the "sources" folder. Use this Removal Utility (direct download) to remove the file from the ISO you downloaded, it takes only 2 seconds!

Note that if you install another edition than Ultimate, you won't be able to enjoy multi-language and to change the display language of Windows with one of the 35 languages available. Only the Ultimate edition has this feature.

If you wonder which edition of Windows to install, be aware that according to Microsoft, all the editions of Windows have the same level of performance (system requirements are the same for all editions). Differences between editions are mainly about functionalities (compare editions of Windows). The Ultimate edition is the edition that includes functionalities from all the other editions, this is the most complete and the most flexible.

H. Should I install the 32 bits or the 64 bits version?
If you have 3 GB of RAM or more, install the 64 bits version. If you have 2 GB of RAM or less, install the 32 bits version. If you have between 2 GB and 3 GB of RAM, both versions are OK, and it's up to you to decide. — Before making any decision, make sure that your processor supports 64 bits instructions. Find your processor on Intel's website or AMD's website and check if it supports either "EM64T" or "AMD64".

J. Where can I find all the official HASHES on Microsoft's website?
Take a look at the TechNet section of Microsoft.com. Select "Operating Systems" on the left panel, then click "Windows 7". The HASHES are on the right side.

K. What is the difference between Retail and OEM version of Windows 7?
There is none. The builds are exactly the same. Only the "Channel" heading in the file "sources/ei.cfg" specifies either "Retail" or "OEM". But this is not definitive since if you use an OEM product key it will switch to OEM, and if you use a Retail product key it will switch to Retail. So at the end it doesn't matter which one you install.


__________________________________________________



6. Advanced stuff

A. How activators work?
Activators, also known as loaders, add a script on the boot partition (Linux Grub boot loader (GRLDR)) which will put OEM information (SLIC 2.1) into memory before Windows starts. This way Windows thinks that the SLIC 2.1 come from the BIOS (which is false). Activators also install a certificate and an OEM SLP key to activate Windows.

B. What about the other method: modifying the BIOS?
To get activated with an OEM certificate and an appropriate OEM SLP key, Windows 7 checks if the computer is OEM branded. To do so, it checks if there is OEM information (SLIC 2.1) coming from the BIOS. Modifying the BIOS imply that we add OEM information (SLIC 2.1) to the BIOS for real.

C. Dual-boot: Windows Vista and Windows 7
If after activating Windows 7, your Windows Vista got deactivated then you might reactivate it in a second:
Reactivate Windows Vista
  1. First thing first: get your Windows 7 activated.
  2. Go back to Vista, if it is deactivated, then continue the steps below.

    • Windows 7 activated with Daz's activator:
      • Apply Daz's activator on Vista.
    • Windows 7 activated with Hazar's activator:
      • Apply Hazar's activator on Vista.
    • Windows 7 activated with nononsence's activator:
      • Launch OpaTool on Vista, type "B" and press ENTER, then type "DELL" and press ENTER again.
    • Windows 7 activated with a modded BIOS:
      • Launch OpaTool on Vista, type "B" and press ENTER, then type the brand name of your SLIC and press ENTER again.
Note that you can also do this process manually if you wish, to do so follow the tiny tutorial in section 6-F-a.
D. Extend the initial 30 days trial period up to 120 days
You can renew the initial 30 days period 3 times for a total of 120 days. Here's a tutorial to renew the activation grace period to 120 days.

How to Rearm and Extend Free Usage (Activation Grace Period) of Windows 7 to 120 Days

Windows 7 (SeVeN) is probably going to continue the trial software trend that starts with Windows Vista’s rearm, that user can install Windows 7 without any product key for free usage of 30 days as evaluation period. During the 30-day activation free grace period, user does not need to activate Windows 7, and can use Windows 7 of any edition in full functionality.

Although Windows 7 product activation function will keep reminding user how many days left to input a product key and activate the system in order to continue using the operating system beyond 30 days. In reality, Windows 7 also equip with a secret ‘rearm’ key in order to reset the free 30-day evaluation period limitation, which allows user to extend the activation-free usage or evaluation expiry date of Windows 7 for another 30 days legally.
Best of all, Microsoft provides 3 times of available ‘rearm’ count, as part of tool for system administrator to reset and restore activation state of Windows 7 to factory state during initial OOB (out of box) grace period. So, by using the ‘rearm’ hack, user can reset and extend the activation grace period (aka evaluation trial period) for up to 3 times, effectively running Windows 7 without product key without activation for up to 120 days, or 4 months. The trick is, the rearm hack must be done only when the 30 days trial period or activation grace period is about to expire.
‘Rearm’ trick on Windows 7 is done using the similar commands and steps with Windows Vista. Follow these steps to reset and extend activation grace period from 30 days to 120 days in Windows 7:
  1. Install Windows 7 without any product activation key.
  2. After installation is completed, use the Windows 7 for 30 days and wait for the remaining days left to activate Windows counting down to 0, or almost zero.
  3. When the activation grace period (or evaluation trial period) is almost expired or ended, log on to Windows 7 desktop, and open a Command Prompt window (i.e. type Cmd in Start Search and hit Enter).
  4. Type any of the following commands into the command prompt, and then hit Enter: sysprep /generalize
    slmgr.vbs –rearm
    rundll32 slc.dll,SLReArmWindows
    slmgr /rearm
  5. Reboot Windows 7 to enjoy another 30 days of free usage without worrying about activation nor even need to crack Windows 7.
  6. When the activation grace period countdown timer almost running down to 0 again, repeat the ‘rearm’ trick to enjoy another 30 days of Windows 7 for free. User can run the rearm command for maximum of 3 times.
As rearm only works for 3 times, make sure the command is only been run when the 30 days countdown of evaluation period is almost expired.

H. Repair startup issues
If you have used an activator and for some reason it broke your system boot partition, you might be stuck at BIOS and Windows won't start anymore. No worry, it can be fixed easily:
  • If you used an activator from Daz, Hazar or nononsence:
    1. Hold the "R" key on your keyboard during startup, if nothing appear try again with the "C" key.
    2. When you see the loader menu, select "Windows without loader".
    3. Once on Windows, uninstall the loader and try another one.
  • Otherwise follow these steps:
Repair startup issues
  1. Put the Windows 7 installation disc in the disc drive, and then start your computer.
  2. Press a key when you are prompted.
  3. Select a language, a time, a currency, a keyboard or an input method, and then click Next.
  4. Click Repair your computer.
  5. Click the operating system that you want to repair, and then click Next.
  6. In the System Recovery Options dialog box, click Command Prompt.
  7. Type (these commands are safe - more information)

    Bootrec.exe /FixMbr
    Code:
    Bootrec.exe /FixBoot
    Code:
    Bootrec.exe /RebuildBcd
    Press ENTER after each command.
  8. Restart your computer.

That should do the trick! However if you still can't start Windows, then follow step 1 to 6 again and type this command (more information about this command):
Code:
Bootsect.exe /nt60 all /force
Press ENTER and restart your computer.
I. My Windows shows an expiration date and/or says that key is invalid
If you get this on the final RTM of Windows 7, this is because you have used Toolkit 1.8 from Orbit or because you have installed a modified version of Windows 7 (e.g. Wzor modified version). It replaced some system files with files from the RC, which was designed to expire on March/June 2010. This can be fixed by making Windows reinitialize those files. To do so you can use the "Repair activation" feature from Hazar's activator, or do it manually if you wish:
Restore original tokens
  1. Type cmd in Start menu.
  2. Right-click on the first result (cmd.exe) and click on Run as administrator (confirm by clicking Yes if required).
  3. Type
    Code:
    slmgr -rilc
    Code:
    net stop sppsvc
    Code:
    cd %windir%\ServiceProfiles\NetworkService\AppData\Roaming\Microsoft\SoftwareProtectionPlatform
    Code:
    rename tokens.dat tokens.bar
    Code:
    cd %windir%\system32
    Code:
    net start sppsvc
    Press ENTER after each command.
  4. Restart your computer 2 times.
J. Tips for a safe and reliable system
Tips for a safe and reliable system
  • When downloading a software from the Internet, always check its authenticity by matching its HASH with the one provided by its official editor (e.g. Microsoft).
  • Only download updates for Windows through Windows Update or from Microsoft.com. Do not install leaked updates, since there are no HASHES available from Microsoft's website, nor any certitude that these updates will be ever released officially, nor any guarantee that it's not malicious software.
  • Do not run .exe files found on P2P networks, forums, blogs, or unknown websites. Always perform a virus check when you don't trust the download source.
  • Do not install anything that modify system files, including (but not limited to) Chew-WGA, RemoveWAT from Hazar, Toolkit 1.8 from Orbit30, and other similar tools that imply changing the way the operating system works by disabling or modifying main features (such as activation modules) or crucial characteristics (such as edition integrity) also known as "Frankenbuild monster".
K. Other loaders available
Here a short list of the main loaders available. They all have more or less the same features, and work similarly.

L. Activate Windows 7 by modifying your BIOS
If the loaders don't work for your computer, and you understand the risk this method imply, then you might try modding your BIOS.

WARNING: This method involves flashing your BIOS. If the flash fails or the modified BIOS is corrupted, your computer will stop working.
  1. Modify your BIOS:
    1. Type dxdiag in Start menu, press ENTER and look for your BIOS type.
    2. Go to the thread that belong to your type of BIOS in the Bios Mods > Bios Mod Requests sub-forum.
    3. If you're lucky, there is already a modified BIOS for your specific computer available to download (use the search function with your computer model or motherboard reference). If not, you can request that a volunteer makes one for you!
    4. Once you've got a modified version of your BIOS, update (flash) your motherboard with it.
  2. Activate Windows 7:
    1. Install a certificate that matches the SLIC's brand of your new BIOS.
    2. Install an OEM SLP key that matches your edition of Windows.

    For these last two steps you can use OpaTool, or do it manually (see section 6-F).

    Note: The certificate must match your SLIC's brand, while the key doesn't. However the key has to match your edition of Windows.

M. Do I really need to use a loader or to mod my BIOS?
If your computer is new, it might be possible that you don't even need to use a loader nor to mod your BIOS. To check that out, follow these steps:
  1. Download the SLIC DUMP ToolKit and run it as administrator (Right-click > Run as administrator).
  2. Select the tab "Advance".
  3. In the "SLIC Diagnosis" section, check if the version is "2.1", and check that there is no red color in the fields "PubKey", "Marker" and "Digital Signature".
  4. If the version is not "2.1" (e.g. "2.0"), or if there is text in red color, then you need to use a loader (or to mod your BIOS).
  5. Otherwise, if you do have SLIC 2.1, then you just need to install a certificate that matches your SLIC, and a valid OEM SLP key. Check out the instructions in section 6-F to install a certificate and a key.
