Citrix or Remote Desktop Service Failure to Disconnect
When launching remote applications through Citrix as opposed to the entire desktop, occasionally the ThreatLocker Tray can cause the session to remain active. This results in Citrix or Remote Desktop Service failing to disconnect after closing an application. If you experience this issue, manually setting the following Windows Registry Keys should resolve it.

Within the SysProcs window, right-click and select DWORD from the dropdown menu.
Type 'ThreatLockerTray.exe' in the textbox that appears at the bottom of the list. Items in this list are processes that can start and not impede your ability to log off your RDP session in Windows. This adds the ThreatLocker Tray to that list.
