I has done this before when it was recently installed (well the other time it was 32bit), much faseter it started booting all slow, the most recent thing to happen explorer stopped responding... I never really do stuff to my sys to mess it up, I know about bitrot that windows seems to suffer from... That most times doesn’t happen with in a few months... Plus, I don't really boot it up until a good game is out to play... That is not a lot with me...
