Windows 10 expired free upgrade offer still works

[Matt Boyz]

I converted my Windows 7 PC to Windows 10 in 2020, when Microsoft was offering the upgrade for free. But I didn’t like Windows 10, so I chose to undo the upgrade. Now that Windows 7 no longer gets security updates, I want to install Windows 10 again. An IT guy told me I might still be able to get it for free, even though the free upgrade offer has expired. Can I?

Yes you can. Once a computer has had a digital licence for Windows 10 you can keep reloading to the same hardware as many times as you like.

Regardless of whether a computer has previously had Win 10 installed on it or not, a Win 7 or Win 8.x machine can still be upgraded to Win 10 for free using the Windows Media Creation Tool that can be downloaded here: https://www.microsoft.com/en-us/software-download/windows10%20.  It's also possible to do a clean install of Windows 10 as long as you have a valid Win 7 or Win 8.x license key to enter when the installer asks for a license key.
