Hi all the error happens when i log off or play steam games,sometimes i can't see the one when i play a game as my game freezes and i'm unable to get to the windows 8 desktop. but the one when i log of it says this program which is .net framework is preventing windows from shutting down. is there a way to fix the .net frame work in windows 8. I have version 3.5 it came with my upgrade from windows 7 and i have the one that came with windows 8 version 4.5. I wish i could get the error message for you all but i cant unless you all know a trick that i don't.
