In a remote desktop connection (Mstsc.exe) to a computer that's running Windows 10, the connection leaks memory when you play any sound. This includes simple beep tones that are generated on the PC speaker.
In this situation, Mstsc.exe may disconnect suddenly and prompt you to reconnect to the remote computer.
This issue occurs because the Remote Desktop ActiveX control, Mstscax.dll, allocates memory for the sound to be played on the client computer, but the memory is never released. This out-of-memory condition causes the remote desktop connection to disconnect and restart itself.
To work around this issue, reconnect to the remote computer.
Note Because this is a new session, you must re-enter your credentials.
Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.
