Dwm.exe stands for a core Windows 10 process called Desktop Window Manager. Even though this is an important process, many users reported issues with dwm.exe on Windows 10.

Users oftentimes experience crashes while gaming, once or more time a day. The screen or screens go black, although the sound is not affected.

Indeed, the system sometimes recovers by itself. However, there’s an underlying cause for the issue and you should investigate more. So we’re going to show you how to fix the issues.

How can I fix DWM.exe issues in Windows 10?

1. Update the controller firmware
