  1. The Interactive Services Detection Service (UI0Detect) is preserved if FireDaemon Zero was deployed on Windows 10 1709 or earlier which is then upgraded to Windows 10 1803 or later
  2. The Interactive Services Detection Service (UI0Detect) has been removed from Windows 10 1803 or later, Windows 11, Server 2019, and Server 2022
  3. The FireDaemon Zero installer will create the UI0Detect service for you
  4. Deploy FireDaemon ZeroInput 0.0.0.4 (For <= Windows 10 1809, Server 2016, Server 2019)
  5. Deploy FireDaemon ZeroInput 0.0.0.5 (For >= Windows 10 1903, Server 2022)
  6. Access to Session 0 via RDP is prohibited and does not work. You will need to use another third-party remote control software such as TeamViewer or TSPlus that provides direct access to the Windows console session to gain remote access to Session 0. Alternatively, you can gain access to Session 0 via the physical or virtual machine console (e.g. via VMware Remote Console - VMRC)
  7. FireDaemon Zero 2.6.2 or later no longer installs on any version of Windows 11. FireDaemon Zero and FireDaemon ZeroInput are not supported on Windows 11. There is no access to Session 0 on Windows 11. Sorry about that.
  8. You can switch to Session 0 without restriction. However, when you switch back from Session 0 you will be returned to the Windows logon screen rather that your user desktop.
