Hi Got a gaming rig which runs clean untouched Windows 7 Professional x64 which I usually disable most of the crap that get's installed like unnecessary services, features etc. and it's always offline with no updates installed more then the usual DirectX, Visual C++, .NET Framework, drivers etc. installed from an cd-r burned by me. Yesterday I played a game in fullscreen mode for a while and when I was done playing and quiting to desktop there had been an appcrash in the background stating that WinSAT.exe had crashed. That's the first time that ever happened before but it's also the first time I tested to have the AERO theme on after an fresh install recently (I honestly don't know if themes have anything to do with WinSAT.exe crashing but I usually turn themes off completely after fresh installs and go with the Classic Windows theme which never caused any problems to me before) Anyway I searched for some information about WinSAT and found out an way to disable it from running through the task scheduler, neat but I also found some other tasks in the background I never thought of before which was scheduled. So for someone here who knows a lot about tasks, is it safe to delete them all completely because by the look of it they seem not to important at all. I honestly don't want unnecessary crap running in the background when I play and do certainly not want any stupid appcrashes. Thanks in advance!
