This problem can be caused by various different reasons. Users can face different errors that basically lead to the Windows 10 activation key not working.

First, we have discussed some of the errors that can cause this problem and also how you can troubleshoot them. After that, we have discussed some other causes and their fixes. This is the most common error that users get when their Windows activation fails.

This error indicates that you have upgraded to Windows 10 but the previous Windows the Windows version your key is from is not installed. You would need to install the previous Windows of which you have the activation key, then update to Windows 10 and then use your key.

Otherwise, your key will fail to activate Windows You will have to do this each time you format or replace your hard disk, as the key is from a previous Windows version, so directly installing Windows 10 may not work. As you may not know, the Microsoft Software License Terms only allow a specific number of computers to have the Windows installed using the product key, as per the license bought by the user.

Check if you have used this product key on computers more than what the Microsoft Software License Terms allow. If yes, then you will have to buy a new product key if you want to install Windows 10 in more computers. Or you can unregister Windows from one of the other computers to install in the new one. If you are facing this problem after you got back your PC from a repair shop, then it is very likely that a different version of Windows has been installed by those in the repair shop while they were repairing your computer.

A different activation key can also be used rather than a different Windows version in this case. You can try reinstalling Windows and then try your activation key and see if it works. If still the Windows 10 activation key not working, then you should check if your Windows is genuine. To check if your Windows is counterfeit, visit this Microsoft page to check if the licensing is correct or download and run this MGADiag. If you find that the Windows you have bought is a counterfeit software, then you should report it to Microsoft by going to this page.

But not everything is great with this change, as the activation is done completely online, so the Microsoft servers have to take a lot of strain. Sometimes the Microsoft servers can be overloaded, thus causing this problem.

Ideally, after reinstalling the same Windows 10 Edition that was installed earlier on the PC, then you need to sign-in with same Microsoft account to get it activated.
