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.

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.

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 spywares 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.

Part 3 of 4: Install Windows 7

You have 2 options to install Windows 7. You can simply burn the 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 . 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.

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".[or you could use any other activator or evemn better use a key] 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.

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 startup 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.

Frequently Asked Questions :
[spoiler]
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.[/spoiler]
