Symptoms

Consider the following scenario:

  • You use Remote Desktop Connection to connect to a remote computer that is running Windows 8 or Windows Server 2012.
  • You disconnect from the Remote Desktop session.
  • You reconnect to the Remote Desktop session, and you specify a different display resolution for the session. For example, you change the display setting in Remote Desktop Connection before you reconnect to the session, or you reconnect to the session from another computer that has a different screen size. 
In this scenario, a memory leak occurs in the Desktop Windows Manager (Dwm.exe) process on the remote computer.

Then, assume that you disconnect from the Remote Desktop session and then reconnect to the session many times, and you specify a new display resolution for the session every time. In this scenario, the remote computer may freeze, crash, or experience a decrease in performance.
