This new version 3.2 has also added support for Google browser Chrome and a better disk defrag and utilities section. The maintain system button addresses four areas of your PC that can slow down your computer - remove spyware, registry cleaning, privacy sweeping, and the deletion of unused junk files.
The system diagnose section will defrag your hard drive and run system tests to see what potential problematic areas of your computer can be targeted and corrected via the software application.

The software will also be available for download when Windows 7 is released.
