Most of MS 'tools' are inferior junk and the system would be better without them. The defragger, antispy (formerly GIANT Antispy, a good program till MS got their hands on it), disk cleanup tool, backup tool and all the rest are junk. So you buy Perfect Disk, Acronis and take your pick on the antispy, Defender places next to last in the 'free' offerings there. And using Windows uninstall is a joke, with programs like Revo Uninstaller available for free. Obviously MS doesn't give a crap about the 'tools' in it's system so I'd prefer they just don't further clutter up the system with them in the first place. And don't hold your breath waiting for any change, in the Windows 7 RC everything's more or less the same.
