oh sorry.. my bad XD
I just figured out that I didn't do it in the right way, I used the "Run" ( winkey+r) instead "cmd", after few times i typed "
del /f %SYSTEMROOT%\Performance\WinSat\DataStore\*.xmlit says it couldn't find any xml files.. so it worked. But I still can't get my pc rated.
Im going to run MBAM in safe mode right now.. just in case.
