Not sure what Windows OS you are using, but if it is XP, goto Start > Run, type in msconfig and click OK. (For clarity, that is MSCONFIG).
In the new window goto the Startup tab and search for any entry for this "Ascentive Registry Repair Program". If it is there, remove the tick.
If this is Vista or Win 7 you may have to use Start > Search to find Run.
In trying to uninstall the Ascentive Registry Repair Program I was successful except for a lingering window at start-up headed "Ascentive Performance Center" that is a constant nuisance.
I have tried using the program Revouninstaller and although it cleaned out the program including the Registry entrees it did not stop the above from occurring. does anyone have any suggestions on how to delete this nuisance. Thanks for your help Calcanuck
