About this tag

In one notable thread, administrators link dwm.dll problems to conflicts with Trend Micro Worry-Free Business Security (WFBS) on Windows Server, where the security agent interferes with the DWM process, causing RDS sessions to fail at consistent times.

These discussions highlight the importance of compatibility between security tools and Windows desktop compositing in enterprise environments.
