Windows 8 Login Screen - Mouse/Keyboard Stop Working

I am having the exact same issue, I had to hard reset the pc 8 times for the keyboard and mouse to start working again.

Tried all above solutions, searched more than 20 sites, still not working...

All those guys who r also having the same KBM not working from login screen, there's on 2 options for u, either reinstall the OS (repairing doesn't work, tried my self n also searched many sites) or back to 7... As right now I'm installing win7 again....

THIS IS A REAL SERIOUS BUG WHICH COMES WITH WINDOWS 8... MS should fix it as soon as possible,,,  3 of my friends who also installed (purchased version, not pirated) r also facing damn fcking issue...... I'll now installing 7 and will install win8 after 6-7months when it will be completely fine..... This WIN8 will not do well in pc business like our old 7 did,,,, this Win8 is like Vista, sooo many issues r there...

Hi,

Thank you for posting in Microsoft community!

You've reached the right forum for your question. As I understand, you cannot enter the password at the login screen. I would suggest you to follow the troubleshooting steps to check if it helps.

1. What is the make and model of the computer?
2. Did you make any changes on the computer prior to the issue?
3. Is the issue confined after upgrading to Windows 8?

You may try to boot the computer in Safe mode and check if the issue persists. Follow these steps to start the computer in safe mode.

a) Press the ‘Windows + C’ key on the keyboard.

b) Click on settings, more pc settings and then general.

c) Scroll down to advanced startup, click restart now.

d) Click on troubleshoot, advanced options, Windows Startup Settings.

e) Click restart, select safe mode and then press enter.

Note: Restart the computer to start in normal mode.

Please reply with the results. I would be glad to assist you further.

I too have the same problem.  I just purchased the upgrade trying to go away from mac for a chance to have MS redeem themselves.  

I cannot enter my password at the login screen and my onscreen keyboard does not load.  I cannot use that either.  My mouse however does work.  I tried the following to rectify the issue.

1. Run the os in a virtualized environment
2. Re seat all usb connections on the hardware
3. Tried a different keyboard
4. Tried a different mode of connectivity on a different keyboard
5. Lastly i tried the windows trick of the trade for generations - reboot three times ...no go.

Please help or please return my money.
