So i ahve been having the same problems as a few people. It's VERY ANNOYING!
Anyway, no one seems ot ave found a fix without wipeing all your programs etc..
Don't take this as a fix, but i somehow have freakishly got all my settings in the CCC back,
I have been messing aroudn trying to intall every driver under the sun.. but non have worked.. anyway i came back to the computer after switching it off, and i made a brand new Hotmail account.
Created it (On the website) Logged off my account, and created a new one and logged in with the new MS account i made.. when i logged and checked my CCC it had all the settings back. Maybe because it was fresh account etc and not copied anything form 7 over?
Get back to me and see if anyone can expend. I am still however having issues opening apps.
