Interactive Service Have Been Removed From Windows 10 1803 or later and Server 2019

Microsoft has decided to remove the Interactive Services Detection Service entirely on Windows 10 1803 or later and Server 2019. Hence,  it's no longer possible to actually switch to Session 0 on that OS version. If you are running Windows 10 1709 or earlier versions of Windows then Session 0 access still works as normal. If you have FireDaemon Zero installed and you upgraded to Windows 10 1803, the Interactive Service Detection Service will be preserved, however, when you switch desktop, you will switch to a blank screen. You will need to deploy our ZeroInput driver to resolve this issue.


Forced Relogin When Returning from Session 0 on Windows 10 1809 and Server 2019 1809

If you RDP into Windows 10 1809 or Server 2019 1809 and switch desktop to Session 0 then attempt to switch back to your logged-in session - you will always be returned to the Windows login screen. We have no fix or workaround for this. Note that you do not see this behaviour if you are logged directly into the Windows 10 1809 or Windows Server 2019 1809 console.


No Access To Session 0 via RDP on Windows 10 1903 or Server 2019 1903 or later

Please note that FireDaemon Technologies Limited is NOT affiliated with nor receives any remuneration from TightVNC, TeamViewer or TSplus. The information provided in the sections below is based on our own internal product compatibility testing.


Switching to Session 0 on Windows 10 1903 or Server 2019 1903 or later over RDP no longer works. It would appear Microsoft is now actively blocked the contents of the Session 0 desktop from being rendered in the RDP session and / or dropping the RDP session entirely. The only workarounds that we know of are:


  • to login to the console session of your workstation or server directly (e.g. via physical keyboard and mouse, via hardware-based workstation or server management gateway such as Dell iDRAC or HP ILO or via virtual machine console offered by VMware vSphere or equivalent).
  • abandon Microsoft RDP entirely and use an alternate remote control product instead such as TightVNC, TeamViewer or TSplus. Your mileage may vary depending on the remote control tool you choose and the particular version of Windows 10 or Server 2019 you use. From our testing, we have found TSplus to work reliably on Windows 10 1903, 1909 and 2004 in conjunction with FireDaemon Zero and ZeroInput.


Deployment Matrix

The table below summarises Zero and ZeroInput compatibility and recommended deployment combinations. Remember to deploy appropriately for your operating system architecture. So if you are deploying Zero and ZeroInput on a 64-bit (x64) operating system ensure you use the x64 Zero installer and x64 ZeroInput driver. The same applies for 32-bit (x86).
