Windows 10 Version 1803

Microsoft have decided to remove the Interactive Services Detection Service entirely on Windows 10 Version 1803. Hence,  it's no longer possible to actually switch to Session 0 on that OS version. If you are running Windows 10 Version 1709 or earlier versions of Windows then Session 0 access still works as normal. If you have Session 0 Viewer or Zero installed and you upgraded to 1803, the Interactive Service Detection Service will be preserved, however, when you switch desktop, you will switch to a blank screen. Consider deploying our ZeroInput driver to resolve this issue.
