* The UI0Detect Service (Interactive Services Detection) has been removed from Windows 10 1803 or later and Server 2019
** The UI0Detect Service is preserved if FireDaemon Zero was deployed on Windows 10 1709 or earlier which is then upgraded to Windows 10 1803 or later
*** The FireDaemon Zero installer will create the UI0Detect service
*** Whilst the ZeroInput driver loads on Windows 11 and Server 2022 it does not work. Hence keyboard and mouse is still blocked on Session 0 on Windows 11 and Server 2022. However, you can switch to Session 0 using FireDaemon Zero but not interact with it. FireDaemon Zero will return you to your logged in desktop after 30 seconds.
