Windows 10: Error 0xc004f50 in upgrading Windows 10 home to Win 10 Pro

Dear Community:I am trying to upgrade Windows 10 Home Single Language version to Windows 10 Pro on my laptop. I have the WIn10 Pro activation key from my organization. I have tried with a couple of valid activation keys but failed. It shows error 0xc004f50 which I have attached as a screenshot. Looking forward to hearing the solution.

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.

 

Windows 10 upgrade questions...

My comments above in red. I did an upgrade from 8.1 Pro to 10 Pro. Then just deleted my Windows.old folder. Saved quite a bit of space (Win 10 installed is smaller than Win 8.1). Overall I'm still enjoying my experience in Windows 10.

As "flawless" as my install was, I do know others have had issues.

 

windows 10 key

Thanks but I don't want to do any decrypting. I want to download a Win 10 ISO from Microsoft and install it using my Win 8 key. No other steps required. Is that possible?
