I love CCleaner from Piriform.

CCleaner is the number-one tool for cleaning your Windows PC. It protects your privacy online and makes your computer faster and more secure.

It keeps my computer clean. I try to run it about once or twice a week; especially if I’m downloading new and testing new programs.

Registry Utility

I use the built-in registry cleaner to clear out the crap that I don’t need. The registry retains a lot of information when you’re installing and uninstalling programs. Sometimes when you uninstall a program, it can leave a lot of crap behind. The registry cleaner in CCleaner clears out that crap.

Startup Utility

Quite a few programs like to load on computer Start-Up. That can be a headache to wait for. Removing the programs that you don’t use often from the computer Start-Up can speed up your computer. It’s a great feeling when you can start your computer and you can do what you need to do without waiting long.
