Hi folks. A ;iitle while back i tried a win7 theme mod (blue progress bars). I was unsucsessfull in doing so although this is not the point of my post. The mod in question involved installing "uxstyles". Clearly i performed some incorrect operation in doing this mod as aero ended up being disabled and no blue progress bars for me, System restore to resolve the aero issue. On two ocassions since trying this mod ive installed updates and when i restart my system i find that aero is disabled and the only way to get it back is to do a system restore from a point just before update installation. FYI, the last update installed was KB947821 , KB917607 , KB976098. Im thinking that i must have messed up something in %windir%resources\themes\aero, just not entirely sure how to go about resolving this. Any ideas appreciated people.
