Most recent Applications will remove their Registry content when they
are uninstalled. Usually, you can check in HKLM\Software and see if
the uninstall left behind a Key Heading (Listed by Company name).
It varies from vendor to vendor. Some Uninstallers do an excellent job
of removal, and some leave pieces behind. Along with Registry keys
some uninstalls will leave the Program Files folder with customization
settings or values to retain if the program is re-installed at a later date.

Do I understand correctly, that XP removes redundant registry entries
left
behind when programmes are un-installed.

Hi All,

I have XP + SP1. I use Microsoft OLD RegClean.

Is this the Best Registry Cleaner Available? Or If not which one I
should
Go
For my XP System?

Thanks
