Windows 10: Windows 10 Key not working after major hardware upgrade; worked fine with old pc

Hi all,


I recently upgraded my PC. Prior to this upgrade my windows 10 was working flawlessly, with no activation issues. Since I upgraded Windows the product key tied to my account has stopped working. I am signed in with my microsoft account that has the product key, and I have tested a vast majority of the microsoft troubleshoots with no luck.


Any help and suggestions would be greatly appreciated.


Yours sincerely,

Mergy

:)

 

Free upgrade still working using old keys


Windows 10 free upgrade offer still works. I tested today. First I installed and activated Windows 8.1 (I used an old Windows 8 key that had never been used) and after this I upgrade to Windows 10.

Note that Windows 10 upgrade installation does not accept Windows 7/8.x product key, so you need to select the option I'm reinstalling Windows 10 on this PC (see screenshot below).





You can also clean install Windows 10 and activate it directly with your unused Windows 7/8.x product key.

Windows 10 upgrade problem, no input accepted

I really hate having to come here and ask for help, but I really am stumped. It hurts my geek pride. I have a PC with fairly modern hardware in it. It has a p8p67 pro in it. I have tried upgrading windows 10 on it twice now. Both times I have had the same result.

After windows finishes upgrading it goes to the log in/set up screen. I can't do anything. No keyboard or mouse input is accepted.

I will list some, or hopefully all, of the troubleshooting steps I have tried:

• Move keyboard and mouse to different USB ports.
• Try different keyboard or mouse.
• Restart computer, repeatedly.
• Google for related issues.
• Update Bios, because why not.
• Create boot media and revert to windows 7.

The windows 10 system restore boot media works fine with keyboard and mouse. All USB ports work in windows 7. I don't know what is wrong. I suspect that windows 10 is lacking a driver of some sort, but since the computer accepts no input I have no way of checking for which driver let alone installing it.

Please help me figure this out. If I have to revert back to windows 7 again, I am not going to get it upgraded to windows 10. Thank you in advanced.

 

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.
