security - How to disable Utility Manager (Windows Key + U)

How do I disable the Windows + U hotkey in Windows XP? Alternatively, how do I stop the utility manager from being active? The two are related. The utilty manager is currently providing a potential security hole and I need to remove it^[1]. The system I'm developing uses a custom Gina to log in and start a custom shell. This removes most Windows Key hotkeys but the Win + U still pops up the manager app.

Update:

Things I've tried and don't work:

1. NoWinKeys registry setting - this only affects explorer hotkeys;


2. Renaming utilman.exe - program reappears next login;


3. Third party software - not really an option, these machines are audited by the clients and additional, third party software would be unlikely to be accepted.

Also, the proedure needs to be reasonably straightforward - this has to be done by field service engineers to existing machines (machines currently in Russia, Holland, France, Spain, Ireland and USA).

^[1] The hole is via the internet options in the help viewer the utility app links to.

Answer

Utility Manager is located in the WINDOWS\system32 directory. The file is utilman.exe. Just renaming the file to something else will stop it from being launched when Windows + U is pressed.
