Desktop Windows Manager (also known as DWM.exe) is the system manager that renders your computer’s user interface by utilizing the graphics card onto your monitor.

It enables all of the visual effects that appear like transparent windows, animations, thumbnails, themes, wallpapers, you name it. It’s all done by DWM.

It’s a pretty old process that was first introduced back on Windows Vista and has since become an important part of Windows computers.

Some users have encountered issues as a message pops up saying that their GPU memory is full, which can cause a lot of stress and confusion.

It’s also the same process that every app and program on your Windows computer uses to display itself on one desktop. However, DWM has the habit of using a lot of your GPU, although this happens rarely.

What you can do instead is update your drivers, turn off visual effects, adjust personalization, and turn off Fast Startup. These are some of the things that you can do to fix DWM from eating too many resources.

Are there other ways to fix problems with GPU usage?

One solution that wasn’t touched upon for Desktop Windows Manager is using antivirus software. In certain situations, malware may be the cause of DWM suddenly using more resources.

Antiviral software is a great way to get rid of that malware and set everything back to normal. Most software that works for Windows 10 also works for Windows 11.

Other GPU problems may be due to high internal temperatures. Normal temperatures range from 149 to 185 degrees Fahrenheit (65 to 85 degrees Celsius) but go a bit higher during intense gaming sessions.

Prolonged high temperatures can cause permanent damage to your GPU, so it’s recommended that you be aware of how hot it gets.

Conversely, there are also solutions for low GPU usage paired up with high CPU usage. It’s a mismatched problem that can be caused by bottlenecking, but not always.

From this strange discrepancy, you may have to deal with frame drops or your processor overheating. This problem may be caused by out-of-date drivers or certain apps getting in the way.
