I was searching for more ways to optimize my computers' startup/shutdown time and ran into this popular utility. Once installed it I ran it and rebooted my system, I must admit I did notice a slight speed increase when I booted. Coupled with the other tweaks I have applied to my laptop I no longer waste valuable time waiting for my computer to shut down. The following is the description for CCleaner.
CCleaner is a freeware system optimization and privacy tool. It removes unused files from your system - allowing Windows to run faster and freeing up valuable hard disk space. It also cleans traces of your online activities such as your Internet history. But the best part is that it's fast (normally taking less that a second to run) and contains NO Spyware or Adware!
