Interactive Service Have Been Removed From Windows 10 1803 or later and Server 2019
Microsoft removed 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 those 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 later
Switching to Session 0 on Windows 10 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. If you try switching to Session 0 your RDP session will hang, you will have to forcibly disconnect and then reconnect to your computer. The only workarounds that we know of are:
- to login to the physical console session of your computer directly (e.g. via physical keyboard and mouse, via hardware-based computer gateways such as Dell iDRAC or HP ILO or via virtual machine console offered by VMware vSphere or equivalent).
- abandon Microsoft RDP entirely and try using 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 TightVNC, TeamViewer and TSplus work reliably on Windows 10 1903, 1909, 2004 and 20H2 in conjunction with the latest versions of FireDaemon Zero and ZeroInput. However, that might change so test carefully and re-test after any Windows updates have been applied.
RDP Session Freeze When Switching to Session 0 on the Console Session on Server 2012 R2, 2016 and Server 2019
If you connect to the physical console of your Windows Server (i.e. the desktop into which the keyboard and mouse are connected) and then switch desktop to Session 0, all existing RDP sessions will freeze until you return from Session 0.
Before installing FireDaemon Zero on any system, please refer to the deployment matrix for important information about compatibility and system requirements.
