How can I download Windows 7 ISO for free?

Windows 7 ISO can be easily downloaded using the official Microsoft website. However, you need an official product key, and if you've one, your problem is solved. Before downloading Windows 7, ensure you know whether your computer is 32-bit or 64-bit to download the correct file.

The only legal way to get a completely free copy of Windows 7 is by transferring a licence from another Windows 7 PC for which you didn't pay a penny – perhaps one that's been passed on to you from a friend or relative or one you've picked up from Freecycle, for example.

Microsoft no longer offers Windows 7 ISOs for download. You can reinstall Windows from scratch using the product key that came with your PC, but you'll have to find installation media yourself. Microsoft offers free ISO files for downloading; you just have to know where to look.

Choose the Windows 10 edition you want to download, then choose the language for which to download the Windows 10 ISO for and choose confirm. Click the 32-bit or 64-bit version of Windows 10 to download to start downloading the ISO file.
