Windows 10: Windows 10 Version 20H2 Upgrade Problem

I decided to install the 20H2 upgrade on my 2 PCs this morning. Both were running version 2004. All went fine on my laptop, but I'm left with a problem on my desktop PC.

The upgrade appeared to complete normally as shown in the specs (see screenshot) however I was left with another problem. When I go to Start --> Power, I see two additional options - "Update and shut down" and "Update and restart." I have tried both but neither correct the problem. Also, if I try to check for Windows Updates, the window just sits in an endless loop and never completes. Other than this problem, the PC seems to functions normally.

Any idea how to fix this?

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.

i've seen this when the stock USB drivers went kaput. Only ever seen it once - i used a PCI USB 2.0 card and connected the mouse and keyboard to that, and manually updated the USB 2/USB 3 drivers.
