This is the software publishers description.

This is so typical. We buy a new PC and soon it slows down to a crawl. Sometimes we just expect too much perhaps. But all too often, the computer is really running slow.

Why? Remnants of programs you once installed are now clogging the memory and disks. The Windows Registry is filled with junk and rarely defragmented. To top it all, Windows runs services you don't need.

Luckily for us, computer owners, most of these problems can be reversed. Auslogics BoostSpeed can speed up your computer by cleaning up and defragmenting disks and the Registry, removing bloated software, and applying performance tweaks.
