Windows 10: Windows 10 update and not accepting password anywhere

I recently updated my PC windows and now when I try to log into my computer it tells me that the device is offline and use the last password used on this device. I have tried resetting the password on the log in screen and online through microsoft. My password works on browsers but not my computer.
It does not accept my password in any safe mode. When I try to open command prompt or use troubleshooting, restore, it asks for my password and tells me it is the incorrect password. I have tried using the on screen keyboard and it still did not work.
I do not want to reinstall my OS because I have a lot of programs and files hat i ahve not backed up and need. Please help if you can.

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.
