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!
My problem is similar in that the keyboard and mouse do not work at the initial windows screen after the auto update of 11/3/15.
Things that seem unique to me are
I have tried restoring but each time I get a message (translated from French) System restoration failed on extracting a file c:\System32\adtschema.dll. The restoration point was damaged or deleted during the restoration.
So it looks as if I now have an electronic brick
Any suggestions as to how to turn this into a computer running Windows 8.1
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.
Why did Microsoft create an operating system for tablets and allow it to be used in desktop pc'????. I have just bought a new Packard bell pc with 8.1 as standard and cant use the keyboard from startup without restarting the thing. This has been written using the screen keyboard and has taken about 4 times longer than it should.
Come on microsoft dont put the blame on another party, its your system you get it sorted.
Where is this xHCI setting in the bios?
To all with this issue I posted with this same or similar problem and eventually found out that somehow under Settings, Ease of Acceess, Keyboard, the Filter Keys setting was on. Setting it to off, restored function of the keyboard and mouse.
I have had to go in and change this setting again a few times, once it switched back to on while I was watching. I think that may have something to do with synch settings on some program. So if you synch something with a setting that causes problems they will propagate to other computers you have synched to . So made sure filter keys off on all my other computers and except once in a while, the problem is gone. But now I can easily fix it, and maybe you can too. Worth a try.
I always thought the problem started after (just to see what it would suggest) I went into Ease of Access and answered the questions to see what Windows would suggest. Boy did that turn out to be a mistake as that is what caused the problem for me. Won't do that again!
