Windows 10: Windows 10: login screen won't accept most keystrokes

I can't log into my computer, because the login screen won't accept any keystroke other than numbers. This problem persists no matter what keyboard I use, including the virtual keyboard. Strangely, though, when I am prompted for a challenge phrase because I have typed my password incorrectly several times, I have full use of whatever keyboard I use, and can easily type the challenge phrase "A1B2C3"

:)

 

After Windows 10 update, signin screen won`t accept my pssword.

Sign-in screen won`t take my password after Windows 10 update on a new HP laptop. I had setup a pin login but now asks for Microsoft password which I wrote down and have used before but will not accept now.

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 Login Login Screen Password/Pin Input Field Won't Accept Any Keystroke

The problem has never happened before. Today when I boot my PC, the password field won't accept any keystroke from my keyboard. Both my keyboard and mouse are working, and they are not the problem. I even able to bring up the password field from the welcome
screen with keyboard. The problem lies in the input field for password/pin.

What I've tried, but didn't work :

1. Use virtual keyboard (from Ease of Access menu). The keystrokes from virtual keyboard also didn't register into the password field

2. Start in safe mode. The login screen in safe mode also didin't work.

3. Trying to use system restore. This one is particularly weird. When I access the recovery menu, I have to input my password in order to use the system restore.
The password field in recovery login also didn't work. Thus I can't even access system restore.

Any help/idea/suggestion is appreciated. Also, I'm somewhat a power user, so don't worry about technicalities. I will understand you.

P/s : This scenario made me appreciate Linux even more. At least if anything happened in the GUI, I can figure it out at the terminal login/output. Now I can't even figure out why the input field can't even register any keystrokes
