are there any free websites where you can run a complete and detailed scan of your windows hardware and software performance without downloading anything . but i can download something if its best to but i prefer not to . i wanted the type of test that shows which programs are using too much cpu and ram as well as a complete check up of windows performance and what i should do to improve windows ? i don’t mean i need a registry scan and repair program . all comments are welecomed . thanks and happy holidays to you .
