I allways use Norton on my XP and 98 machines, but like all regcleaners you can't let them do an automatic repair, because these progs want restore shortcuts and other files from the trash bin.
Some progs want to delete empty uninstall-strings. Why? In many cases the programmer has placed these strings as a flag!
And why want they delete the shortcuts? After an hour they are back!
Happily you can make an ignore-list.
I hate Registry Mechanic, it corrupted my scanreg.exe.
