Download Official Windows ISO Files Free from Microsoft

Did your computer come pre-installed with Windows or would you like to downgrade to a previous Windows version?
If you’re seeking Windows installation files, the good news is, they’re available for free from Microsoft. You can easily create Windows 10 installation media and you can legally download Windows 7 and Windows 8.1 ISO files from Microsoft, too. The only requirement is that you own a product key for the respective Windows edition.
Here we’ll show you a little hack that allows you to download any edition of Windows 7, Windows 8.1, and Windows 10 from Microsoft’s Tech Bench.

The Source of the Hack & What You Need

By default, the Microsoft Tech Bench page only offers the latest Windows version for download, presently Windows 10. By examining the source code of the site, however, WZor, Nummer, and adguard, three prolific Windows leakers, found that it contained download links to many other Windows versions and editions.
They wrote a script to make all download links available directly from the Tech Bench drop-down menu and published it as Windows 10 Tech Bench Upgrade Program HACK on Pastebin.

Applying the script is easy. All you need is a browser, the ability to copy and paste some code, and 3-4 GB of space for the Windows ISO file you’re going to download.

Here’s a quick review of the entire process from the hack masters themselves.
As mentioned above, you’ll need a valid product key for installation, so most of you will only be able to use the Home or Pro editions of Windows.
To download a Windows ISO file, make your selection and click Confirm (WZT).

Finally, you’ll be able to download the 32-bit and / or 64-bit Windows ISO file. Note that the links will expire after 24 hours from the time of creation.

If you’re installing from Windows 8.1 or 10, you can mount the ISO file (right-click > Mount) and launch the installation directly. Alternatively, you can create a bootable Windows installation USB drive with several free tools, such as Rufus.
For detailed instructions from Microsoft on how to create an installation USB stick, install Windows on an old or new PC, and a quick start guide for Windows 10, you can download the Windows 10 Tech Bench Upgrade Program Documentation (ZIP file). The package also contains the end user license agreement (EULA) and the privacy statement for Windows 10.
