Windows 10: Can I reactivate windows 10 using original OEM licence key after re-installing windows 10...

I bought a desktop with windows 10 pro pre-installed which was activated with a OEM key. I wanted to upgrade to the latest build of windows 10 pro and since the desktop is not connected to the internet I downloaded the latest windows 10 pro ISO using my MSDN account and installed that. However it now says that it is not activated. I can activate it using my MSDN licence keys but I really want to activate it using the in-built OEM key.

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.

You need to upgrade the first time around. Once you upgrade, you can use that key for a clean installation. I've done 2 clean installations with my Windows 7 key since I upgraded to 10 the first time around.

Now that I have finally upgraded from Windows 8 to Windows 10 will my Windows 8 key work with a fresh install of Windows 10?
