Ever wonder how to keep Windows running nice? I recommend using three tools.
First, I recommend using CCleaner. CCleaner cleans your registry (save a backup) and startup to allow your PC to boot faster. It can also free a dramatic amount of space by deleting temporary files (4% of my HDD on my PC). Second, I recommend Spybot Search and Destroy. It works really well to speed up your computer and helps privacy. Third, I recommend Defraggler. It defragments your files to make your PC run faster and more efficiently. CCleaner, Spybot, and Defraggler will help you keep your PC running well.
