If you want to know how to get rid of ghost listings in Add/Remove (Start, Settings, Control Panel, Add/Remove), check this out. Ghost listings are programs that no longer exist on the computer. You'll get ghost listings if you delete a program without using Add/Remove. And you sometimes get ghost listings even when you DO use Add/Remove to uninstall a program.
There is a way to delete these listings, but they require that you edit the Registry. So be careful. And before you start, make absolutely sure that you do want to get rid of a listing. If the program still exists, you won't be able to uninstall it once you've deleted the listing.
Click Start and choose Run. Type
regedit
and click OK (or press Enter). Navigate to
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall and locate the offending entry. Select it and press Delete. Close RegEdit and restart the computer.
