It's maddening. You delete a program but it still shows up in Windows' "Add/Remove Programs" applet. Click the name and nothing doing. Windows says it's not there to remove--but it leaves the name in the box.
Sure, this is a niggling detail, but why put up with it at all? Instead, install Add/Remove Plus, a 1.2MB freebie available from http://www.aurelitec.com/software/arplus/download.htm. It's advertising-supported (a no ad version is yours for $12.50), but the ads are a small bother. A 15-minute session and, voila, your Control Panel Add/Remove list is accurate.
