Dummy entries in Add/Remove Programs list
Sometimes, even after programs are uninstalled, or due to the files being deleted instead of a uninstalled, the entry in the Add/Remove Programs list does not get deleted. To remove it from the list:
1. Start the Registry Editor.
2. Open HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall.
3. Delete the program entry here.
