If you're thinking of going to windows 8.1 DON'T ..... 
Some users (including me) get very retarded mouse "issues" pretty much  every fps game is unplayable now.
I tried all the fixes non of them work . 
Ex: Black Ops 2   old mouse sensitivity 3.69 (had perfect aim with it ) 
now  5 feels like 1  and  7 feels like 20 
Bf3: mouse goes all over the place  
CS 1.6 : worst of all changing mouse settings doesn't effect anything  
and its totally unplayable 
If anyone had this problem and fixed it i would be very glad if they tell me how they fixed it .
Oh SteamOs where are you
