Ive enabled Ultimate performance trough cmd, but everytime I reboot my PC or leave it idle for a while it goes back to high performance. Ive already reseted my PC once because of this but it seems it didnt fix it. Any ways to fix it?
it doesn't delete anything, it just stops non Microsoft programs from running with startup. easy to reverse
if clean boot fixes it, it shows its likely a startup program. You should, over a number of startups. restart the programs you stopped to isolate the one that is to blame.
