Quick tout, been using CCleaner free version from Piriform for ages, good program, but had something it couldn't uninstall on my Win 7 and IObit Uninstaller was able to get rid of it.
Was also recently moving a bunch of files around and needed to defrag, but Piriform's free version of Defragler would not do much defragging on a 1 TB drive, Windows defrag wasn't really cutting it either, bu IObit Smart Defrag worked very well, with the functionality of previous versions of Diskkeeper Pro.
IObit likes to sell you on trying Dashlane, but their free versions of uninstall and defrag are really good, just uncheck the Dashlane trials.
