I have Windows XP Home, and have TuneUp Utilities 2006 which has a Registry Cleaner.
I just purchased Max Spyware Detector, on promo I can get the Max Registry Cleaner.
Can you have 2 Registry Cleaners on one computer?

Thank You :)

You sure can, no problem. Run one, then run the other to see if it finds anything else.

A hint/warning (my experience only): I swore off Reg Cleaners long ago - when I realized that every one will find something that another did not find... and I have yet to see one that runs, does it's stuff, and leaves me without "side-effects". That is, stuff that's changed that I did not want changed.

Use Registry "cleaners" with care!
