Alright, it seems as if my computer has been slowing down over the course of its lifespan. I have defraged it and ran disk cleanups, which did work for a good amount of time, but I wish to do more for maintain it.
What else should I do to speed up my PC? Can I trust stuff like CCleaner?
They can be done separately. Let the program analyze the registry.It'll then show the number of errors once it is done.This is when you can clear the errors.CCleaner will ask you if you want to backup your registry prior to cleaning it.
Startup programs can be disabled at any point.No worries there.
