Desktop Window Manager high CPU usage in Windows 10

If you are experiencing high CPU usage on your Windows 10 computer, it could be due to the Desktop Window Manager (DWM) process. DWM is responsible for managing visual effects such as transparency and 3D effects on your desktop. However, sometimes it can consume a lot of CPU resources, causing your computer to slow down.

Here are some steps you can take to fix the high CPU usage caused by DWM:

1. Update your graphics card driver: Outdated or corrupted graphics card drivers can cause DWM to consume more CPU resources than necessary. To update your graphics card driver, go to the manufacturer’s website and download the latest driver for your graphics card.

2. Disable visual effects: If you don’t need the visual effects on your desktop, you can disable them to reduce the load on DWM. To do this, right-click on the desktop and select “Personalize.” Then, click on “Themes” and select “Desktop icon settings.” From there, click on “Advanced system settings” and select the “Settings” button under the “Performance” section. Finally, select “Adjust for best performance” and click “Apply.”

3. Disable transparency: Transparency effects can also cause DWM to consume more CPU resources. To disable transparency, go to “Personalize” and select “Colors.” Then, turn off the “Transparency effects” toggle.

4. Disable hardware acceleration: Hardware acceleration can cause DWM to consume more CPU resources. To disable hardware acceleration, go to “Settings” and select “System.” Then, click on “Display” and turn off the “Hardware-accelerated GPU scheduling” toggle.

5. Restart DWM: If none of the above steps work, you can try restarting the DWM process. To do this, press “Ctrl + Shift + Esc” to open the Task Manager. Then, find the “Desktop Window Manager” process and right-click on it. Finally, select “End task” and wait for the process to restart.

By following these steps, you should be able to fix the high CPU usage caused by DWM on your Windows 10 computer. If the problem persists, you may need to seek further assistance from a professional.

Conclusion

I hope these steps were helpful in resolving the high CPU usage caused by DWM on your Windows 10 computer. If you have any further questions or concerns, don’t hesitate to seek assistance from a professional. Thank you for using our service.
