Hi,
I just updated to Windows 8.1 last night. All went fine. Once it had finished it booted to windows normally. I then decided to restart the computer just to make sure everything was okay and sorted.
It took me to the normal login screen. My Keyboard and Mouse didn't work?! I check all of my peripherals and non of the USB devices were working. I have tried multiple times to restart and try different USB's to no avail. I have tried a bog standard keyboard and mouse and even a PS2 slot keyboard and non of this has worked.
Any help on what I can do without losing all of my data?
**UPDATE**
I found a solution that worked for me. If you try this, hopefully it will work!

Hi guys,
I have found a solution to the problem via a person from another forum with the same issue. All credit goes to him for finding this out. If you try what he says it should work fine. It did for me

Hope it works for you all!
Hello, it worked for me too. I disabled xHCI mode and everything works now.
Hi Sam,
Thank you for sharing the information.
This will help others who are facing the similar issue.
Since the BIOS settings need to be modified to disable Intel XHCI Mode, for further assistance you may contact the computer manufacturer.
Important: Modifying BIOS (Basic input output system)/complementary metal oxide semiconductor (CMOS) settings incorrectly can cause serious problems that may prevent your computer from booting properly. Microsoft cannot guarantee that any problems resulting from the configuring of BIOS/CMOS settings can be solved. Modifications of the settings are at your own risk.
Let us know if you need further assistance with Windows related issues. We will be happy to help.
I have the same exact problem. This is absolutely ridiculous. I upgraded to 8.1 and after reboot no USB at all. Multiple keyboards = nothing.
This is a disgustingly pitiful bug that should have never seen the light of day. A PC without a keyboard/mouse is called a TV. A bad one at that for at least a TV has a remote to control it.
Fix this Microsoft.
Same issue. Installed Win 8.1 from Win 8. Everything was fine until I rebooted, then no mouse or keyboard. In fact, no USB at all. None of the ports work. I tried to do a restore, but that did nothing. My computer is custom built, AMD chipset. Computer is fine as everything works in bios and I can load linux just fine. Something is wrong with Win 8.1 or some driver issue with the USB.
