  1. doesn’t work on windows 10 pro 1909. startup type is greyed out and will NOT let me change it via gui, command line; SC command or powershell set-service cmdlet

    very annoying as the damn service keeps running on its own and consuming my cpu usage. I have to end task on the process every couple of minutes while trying to use my system.

    1. Hi Rick,

      You may try to disable the services using MSConfig >> Services >> Disable. This might help to disable a specific application running in the system background.
