Ever since the official release of Windows 10 back in 2015, over 500 million PC users have upgraded their Windows 7/8.1 installations to Windows 10 using the free upgrade offer.
If you upgraded from Windows 7/8.1 to Windows 10 or plan to do so in near future, you probably are aware that you need to upgrade your current Windows 7 or Windows 8.1 installation to Windows 10 in order to get the free upgrade and it’s not currently possible to activate Windows 10 using your Windows 7 or Windows 8.1 product key.
Microsoft’s decision not to let users activate Windows 10 using genuine Windows 7/8.1 key has forced many users to upgrade their Windows 7/8.1installation to Windows 10 even if they wanted to perform a clean install of Windows 10 from ISO. Although once the Windows 7/8.1 installation is successfully upgraded to Windows 10 and activated, it’s possible to easily reinstall Windows 10, many users are experiencing activation issues after the clean install.
Activate Windows 10 using Windows 7, Windows 8 or Windows 8.1 key
It looks like Microsoft has taken this activation issue as well feedback very seriously as Microsoft announced earlier last week that users would be able to activate their Windows 10 by using genuine Windows 7, Windows 8, Windows 8.1 product key. What this means is that millions of PC users who are yet to upgrade to Windows 10 or over a hundred million users who already upgraded to Windows 10 will soon be able to activate Windows 10 by entering their Windows 7, Windows 8, or Windows 8.1 product key.
This method of activating Windows 10 using Windows 7/8.1 product key works only if you attempt to activate Windows 10 on a PC or device which was previously running a genuine copy of Windows 7, Windows 8, or Windows 8.1. That is, if you were running a legitimate copy of Windows 7/8/8.1 on your PC, you could use this method to activate Windows 10.
To activate Windows 10 by entering your Windows 7, 8 or 8.1 product key:
Step 1: Open the Settings app. Navigate to Update & Security > Activation page.
Step 2: Click the Change product key button.
Step 4: Enter your Windows 7, 8 or 8.1 product key and then click the Next button to activate your Windows 10.
