We applied KB5052093 to a couple of PCs and those PCs are having issues with disconnects to our RDS farm.
We have a shared app on an RDS farm and after installation of KB5052093, the shared app "glitches" on the client PC. Best case, this glitch presents as a brief flash of the app GUI. Worse case, it triggers a login request (which our app requires to open).
On the RDS server we see the following event combos every few minutes for the user under Event Viewer->Applications and Services logs->Windows->TerminalServices-LocalSesionsManager->Operational
Event 40
Session x has been disconnected, reason code 0
Event 25
Remote Desktop Services: Session reconnection succeeded
Uninstalling KB5052093 resolves the issues as does enabling "Turn off UDP on client".
Go to GPEDIT -> Administrative Templates -> Windows Components -> Remote Desktop Services -> Remote Desktop Connection Client and change the value of the rule "Turn off UDP on client" to Enabled
I know KB5052093 was supposed to fix some RDP issues. The KB does appear to update MSTSC.exe.
Has anyone else seen this issue? Has this been reported?

We had the same issue. I can confirm that it only affects 24H2 installations, and uninstalling it or rolling the OS back resolves it. I will try the policy that you mentioned.

Hello，
The latest update KB5053598 has been released, you can install the latest version. This security update includes improvements that were a part of update KB5052093 (released February 25, 2025).
You can follow this link as a reference : https://support.microsoft.com/en-us/topic/march-11-2025-kb5053598-os-build-26100-3476-a248e951-daef-43ad-aa10-0b99f551cec2

I tried applying KB5053598 on two, yet to be affected, systems that never had KB5052093 installed. I'm having the same RDS issues after installing KB5053598. Uninstalling KB5053598 resolves the issue as does the disabling UDP which I mentioned in my original post.
