How to Use a Windows 7, 8, or 8.1 Key to Get Windows 10 It’s possible that Microsoft will disable it soon, but it’s also possible Microsoft will look the other way and keep this trick around to encourage more Windows 10 upgrades for a long time to come. Microsoft hasn’t released any sort of statement about this upgrade method at all. Enter any Windows 7, 8, or 8.1 key that hasn’t previously been used to upgrade to 10, and Microsoft’s servers will give your PC’s hardware a new digital license that will allow you to continue using Windows 10 indefinitely on that PC. It works when installing Windows 10 with installation media or by entering the key after installing Windows 10. Now, even though the free upgrade offer is technically over, this method still functions in every version of Windows 10, from 2016’s Anniversary Update to the November 2019 Update.
