tbontob,
you need to have Clean Sweep running _before_ installing any of your programs for it to be able to properly remove all the files. This means, it uses your system resources. If you like that - use this program. From my experience, most of the programs are very nicely uninstalled (not deleted) using windows uninstaller.
Actually, if the program is well done, it creates an uninstall file itself. All installation files are logged into some logfile.log. Then both win.uninstaller and cleansweep just launch the uninstaller and that's it.
