The last problem to solve Windows 10 is a new issue that causes the Windows Desktop Manager (DWM) to stop responding when the laptop cover is opened and closed repeatedly, or if the laptop is stuck and not broken. several times. As a result, laptops are crashing unexpectedly.
According to Microsoft Support, “This problem occurs because of a problem in the Microsoft DirectX Video Memory Management (Dxgmms2.sys) component.” The documentation also indicates that this is related to a bug in the Microsoft DirectX Video Memory Management software, and not a hardware problem.
Under certain circumstances, repeated opening and closing, or marking and tying of a laptop when connected to external monitors, will cause the Windows Manager (DWM.exe) process to stop responding.
Windows Desktop Manager is the software that supports adding monitors, adjusting the display to different resolutions, managing visual effects for desktop activities, and managing desktop activity. desktop on multiple screens. Errors in this software can result from everything from improperly sized icons to a full system crash that requires you to restart the system altogether.
Microsoft has identified two scenarios that trigger this Windows Manager bug
Insert a HDMI monitor High Definition Multimedia (HDMI) monitor into a laptop computer running Windows 10.
The monitor is configured to work with 4K resolution.
You repeatedly play 4K H264 video in Movies & TV on the computer.
In the Control Panel, you should open the Advanced Power Options Item settings screen, and then you should set the Aid close as Do Nothing.
While the 4K video is playing, you repeatedly close and open the computer cover.
Connect two 4K monitors to a Thunderbolt 3 docking station.
Connect a laptop that has a 4K solution monitor to the docking station, and then you configure a triple configuration of a 4K display in either “clone” or “extend” mode.
You repeatedly loosen and replace the laptop.
What to do if you are affected
In any of these situations, switching back and forth between the monitors and the laptop seems to cause problems in the DWM.exe process.
Microsoft is working on a solution to this issue. Meanwhile, the simplest solution is to avoid unnecessary closing or rooting of the lid, and restart the system to return to normal functioning if a problem is found.
