Users close the Remote Desktop window and walk away, but their session keeps running on your server for days - holding RAM, open files and a live login. Session time limits fix this properly: idle users are warned, then logged off automatically. Here is the complete setup, the Group Policy way and the RDS collection way.
Every Remote Desktop server collects ghost sessions. A user finishes work, clicks the red X on the RDP window and goes home - but clicking X only disconnects the session. Their desktop, their open Tally or Excel files and their login stay alive on the server, using memory and keeping a signed-in account open all night. Multiply that by twenty users and a small server starts crawling for no visible reason.
Windows already has the cure built in: session time limits. Configured the right way, a session that sits idle too long is warned and then logged off - applications closed, memory freed, login ended. This guide sets it up two ways: Group Policy, which works on any Windows Server or Pro PC hosting Remote Desktop, and the RDS collection settings, which are the cleaner route on a full Remote Desktop Services deployment. The video above shows the quick version; this page gives you the why behind every setting so you can tune it instead of copying blindly.
Open Task Manager on the server, go to the Users tab, or run query session in a command prompt, and you will see sessions in different states. Active means the user is connected and working. Idle means connected but not touching keyboard or mouse. Disconnected means the RDP window is closed but the session - and every app inside it - is still running on the server.
This distinction matters because Windows has a separate policy for each state. One policy cannot do the whole job. Admins who set only an idle limit wonder why disconnected sessions from Friday are still alive on Monday: they set the wrong half of the pair.
On the session host server, open the Group Policy editor - gpedit.msc for the local machine, or the Group Policy Management Console (gpmc.msc) if you manage many servers from a domain. Then navigate to:
Computer Configuration > Policies > Administrative Templates > Windows Components > Remote Desktop Services > Remote Desktop Session Host > Session Time Limitsgpupdate /force on the server, or wait for the policy to refresh on its ownThe same policies also exist under User Configuration. Prefer the Computer side for a server-wide rule, so the limit follows the server no matter which user signs in.
If your server is a proper Remote Desktop Services deployment, collection settings are cleaner because different user groups can get different limits. Open Server Manager > Remote Desktop Services > Collections, open your collection, and under Properties edit the Session section.
There you get the same family of controls in plain language: End a disconnected session after, Set time limit for active but idle sessions, and the choice of what happens when a limit is reached - disconnect the user or end the session. Pick end the session when your goal is a true logoff that frees resources.
One honest note: collection settings and Group Policy can both exist, and Group Policy wins when they conflict. Pick one place to manage session limits and write it down, or the next admin will chase a setting that keeps being overridden.
A logoff is not a pause. Windows closes the session's applications, and anything unsaved in them is gone. That is exactly why this feature is valuable - it really does free the RAM, the file locks and the login - and exactly why it must be rolled out with a warning and a test, not silently on a Friday evening.
Also be honest about the 5 minute number from the video title: five idle minutes is right for a shared kiosk or a billing counter terminal, but a staff member reading a long PDF or sitting in a meeting with their session open will trip it constantly. The mechanism matters more than the exact number - set the limit your users can genuinely live with.

The session keeps running on the server - applications stay open, files stay loaded, RAM stays used and the user is still signed in. Logging off ends the session completely: applications close, memory is freed and the login is finished. Session time limits can do either; the End session when time limits are reached policy is what makes them log off instead of only disconnecting.
Two policies working together: Set time limit for active but idle Remote Desktop Services sessions defines how long a connected session may sit unused, and End session when time limits are reached makes the action a logoff instead of a disconnect. Both live under Computer Configuration, Windows Components, Remote Desktop Services, Remote Desktop Session Host, Session Time Limits. Add Set time limit for disconnected sessions so abandoned disconnected sessions are cleaned up too.
Yes, it can. A logoff closes the session's applications, and documents that were never saved are lost, exactly as if the user had logged off manually with files open. This is why the honest rollout is: warn users first, start with a long idle limit, use the on-screen warning Windows shows before the limit hits, and test with one account before applying it to everyone.
