How to Fix Remote Desktop Session Freezes Disconnects on Windows

In this blog, we will provide the different methods to fix Microsoft Remote Desktop session freezes and demonstrate the possible reasons. Remote Desktop appears to freeze constantly if your experience is anything like mine. Mouse clicks seem to work, but the remote screen stops redrawing. The only resolution is to disconnect your Remote Desktop session and establish a new one, only to freeze up again a few minutes later.

There is a solution to this freezing issue. Since I made this change to my computers, remote desktop sessions have stopped responding once on any of them. I work remotely every day, so there are a few hours behind this test. I hope this solution works for you.
