How to disable Utility Manager (Windows Key + U)

Solution 1:

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.

Solution 2:

I've experience similar problems in the past - the best solution I have found is to alter the permissions of the utilman.exe so that no user has the rights to run it:

Right click - properties - security - Deny all.

Solution 3:

In Utility Manager properties I went to security tab and disabled access to all users (for administrators as well) and after doing that it does not run.
