Windows 10: After updating to windows 10 from a genuine windows 7, it asks for an activation key

As the title says, I just upgraded from windows 7 to 10, but now it's not activated and asking for a product/activation key. Any help in resolving this issue would be appreciated.

Windows 7 not genuine problem

It seems like that's an OEM windows copy, it will do that the every time you reinstall the OS. If you have the key, next time you see the "not genuine windows copy" click it and choose to activate by phone, everything else is pretty straight forward as it explains step-by-step. If it doesn't work, then its highly likely that you got a Pirate copy.

 

Installing Windows 10 using Windows 7 key

Nope, you need to install Windows 10 first and make sure the Windows 7 key is transferred to your Windows account after you've installed Windows 10 (not quite sure how that works). I missed the last step and I could not activate Windows 10 after a re-install... Microsoft seem to have done everything they can to make it a PITA. Also, it's technically too late to do this now anyhow, as the upgrade offer has expired. But KMSPico works quite well...

As for getting rid of Windows, delete the Windows folder.

 

Installing Windows 10 using Windows 7 key

Two quick ways to use your Windows 7 key during the install:

1. When asked for the serial #, put in that Windows 7 serial # and continue on. It should activate as soon as it hits an internet connection.

2. When asked for the serial #, at bottom of window click on the I don't have a serial # text (or whatever it says). It will then ask what version you want to install, ie. Home or Pro. Be sure to install the right version that matches your Windows 7 key. Then once you get into windows you can activate by putting in the key. Some people prefer this method, not sure why honestly. Easier to do #1, since the installer will see your key and know which flavor of Windows 10 you are trying to install.
