More and more require 8.1 so while I've yet to see an 8 to 8.1 failure, I read about them. On yours there is no detail about the PC so for now, just turn off WU.
i am happy with windows 8. but every time it updates to windows 8.1 the screen keeps flashing from blue (with no apps) to desktop that dose nothing. i need to know witch update to turn off. right now i got updates off but need to perform this funtion. thanks for any help
