Sadly, nothing ENFORCES that an added program be listed in the Add/Remove list. Some new users don't notice the scroll bar on the list either.

If you add a program that doesn't list in the Add/Remove tool, see if they provided an uninstaller or if push comes to shove, you can use a manual method of deleting it's program directory and it's shortcuts.

The more advanced user will use a tool like the formerly freeware JV16 powertools kit noted at http://www.321download.com/LastFreeware/ to delete the programs litter in the registry.
