XP Repair Pro will help you controling that, because it deletes fast and easily (5 minutes aprox.) all errors in your computer.
XP Repair Pro can locate about 15.000 errors in the windows registry, organising them by categories. In addition, before eliminating them, it creates a backup in case the system becomes more unestable.
You will be able to analize the resources usage, control windows events and uninstall programs.
The trial version shows you the errors but it doesn’t repair them
