how can i uncompress mouhid.sys listed in blue

[ronhud]

I have a PC that had Windows 8 installed and then when I upgraded to 8.1 I installed it on a new hd. it shows both 8 and 8.1 as choices at boot up. Everything has been going fine until today when I find that when the boot reaches the 8.1 splash screen (just prior to login) there is no mouse or keyboard response. If I login to Windows 8 I can see that on the other hd in system32\drivers folder a number of files including mouhid.sys and kybdhid.sys are shown in blue which I think means they are compressed.

How can I uncompress them since I can only work from Windows 8 on the different hd.

to be clearer :-
boot into Windows 8
hd 1 has Windows 8 installation and old data
hd 0 has windows 8.1 installation with current data but mouhid.sys ect are compressed.

How did you 'upgrade' to 8.1? And then install on a new drive?
8.1 is a free upgrade from the Store.

Thanks for responding. I checked again and I have windows7 on one hd and Windows 8 and 8.1 on the other hd - sorry to have been confused. Present state is that when I boot and reach the choice of os screen I have active keyboard and mouse. If I choose Windows 8 it continues as it should and I can use the pc as normal. If however at the os choice screen I choose Windows 8.1 then when I reach the screen before login (sort of rainbow display) I have no mouse and keyboard and so cannot continue to login etc.

If I look at the system32/drivers folder for the 8.1 installation lots of the files are in blue but I dont know whether this would affect the availibilty of mouse and keyboard.

I have been using 8.1 for some time now and desperately need to be using it again. I am wondering what happens when a choice of os is made - does windows then reload mouse and keyboard drivers?

If you had upgraded to 8.1 normally through the Store, there should not be a choice between 8 and 8.1

How did the 8.1 get on that drive?

I did upgrade to 8.1 from the store so I am not sure how the present state came about. Should I delete 8 and if so how and if I do will that cure the problem with 8.1 or will I be left with an inaccesible 8.1 and no 8?

Still a little unsure here.

Original 8, then upgraded to 8.1, but also Win 7?

What did you start with, what did you do, what do you have, and what do you want the end state to be?

Strange situation to end up in!
A suggestion that might help...
First ensure you have a Recovery or Installation Media to hand.
Try Windows key plus R and type msconfig then enter
What do you see on the Boot tab? Probably two entries, one for Windows 8 and another for Windows 8.1
Note down the path to windows 8 in case you need to re-instate it.
Remove the entry for Windows 8 and Restart your machine. If the keyboard/mouse are still unresponsive, reboot from your Recovery/installation drive and use Troubleshoot then Advanced Options to run SFC from CMD prompt to see if the problem can be fixed (sfc /scannow) then enter
