Removing Programs listed in the Add/Remove Programs Box

All Windows programs must include an Uninstall program, sometimes though the program may get removed but entry in Add/Remove programs doesn't, from this key you can remove those orphaned entries.

Using Regedit open the key below. Under this key will be a number of sub-keys, each representing an installed application.

[HKEY_LOCAL_MACHINE \ SOFTWARE \ Microsoft \ Windows \ CurrentVersion \Uninstall]

To see which application each sub-key represents, open it and there should be at least two values 'DisplayName' and 'UninstallString'. 'DisplayName' is the name used in the Add/Remove programs list, and 'UninstallString' is the program used to uninstall the application.

To remove a program from the list you can simple delete the sub-key representing that program.
