tried revo uninstaller, but so far did not get any real benefit of it, it seems to mostly do what windows does anyway... it does claim that it can check the registery and cleanup application left-overs but so far it didn't do what it claimed to do. I tried with my friends laptop who had an application installed, it was a game and it was not in the Add/remove programs. according to the product instructions, you can drag and drop the shortcut to revo then it will detect if it's installed or not, but it didn't detect it. so I just had to delete the whole directory, could not delete the registery stuff though.
