In this guide, we will walk you through the most effective methods for fixing DWM high GPU. We’ll also provide some helpful tips for preventing the issue from happening again.

What is Desktop Windows Manager (DWM)? 

DWM is a process that is responsible for managing and displaying the desktop environment in Windows. It handles things like window transparency, live thumbnails, and Aero Glass – which is why it’s often referred to as the “Aero process”. DWM uses GPU resources to render the desktop, which can lead to high CPU usage if there are a lot of windows open or if the graphics settings are set to high.

What are the symptoms of DWM high GPU usage? 

There are a few different symptoms that you may experience if you have DWM high GPU usage:

  • Your computer’s performance may suffer, and it may feel sluggish: This is because DWM is taking up valuable resources that could be used by other programs.
  • You may see visual artifacts on your screen: This can happen if the GPU is overloaded and can’t keep up with the demands of DWM.
  • Your computer’s battery life may be shorter than usual: This is because the GPU is using more power when it’s under load.
  • Games and other full-screen applications may stutter or lag: This is because DWM is taking up resources that could be used by the game.

Causes of DWM high GPU usage 

There are a few different things that can cause DWM high GPU usage:

  • Too many windows open: If you have a lot of windows open, it puts more strain on the GPU and can lead to high CPU usage.
  • High graphics settings: If you have your graphics settings set to high, it will also put more strain on the GPU.
  • Full-screen applications: Games and other full-screen applications can also cause DWM to use more GPU resources.

Update Outdated Graphics Drivers

  1. Download the latest drivers from the manufacturer’s website. You’ll need to know what model of graphics card you have, so you can download the correct drivers. To do this on a Windows 10 computer, open the Device Manager and look under Display Adapters. The model name will be listed next to the word “Intel.” If you see more than one adapter listed, then you have multiple graphics cards installed in your computer. Repeat this process for each card.
  2. Uninstall the current drivers. Once you’ve downloaded the new drivers, you’ll need to uninstall the old ones. Again, open the Device Manager and expand Display Adapters. Right-click on each adapter and select “Uninstall.” Confirm that you want to uninstall the drivers when prompted by clicking “OK.”
  3. Install the new drivers. Now that the old drivers are uninstalled, you can install the new ones. Double-click on each driver file that you downloaded and follow any prompts that appear. If you’re asked to restart your computer after installing the drivers, do so.
  4. Reboot your computer. Once you’ve installed the new drivers, reboot your computer for the changes to take effect. After rebooting, open the Device Manager and make sure that there are no errors listed under Display Adapters. If you see any errors, try reinstalling the drivers. Otherwise, your graphics drivers are now up to date.

  5. Finally, restart the computer one more time to complete the process.

By following these simple steps, users can ensure that their graphics card is always up to date.

Disable Aero Glass Transparency 

Windows 10 includes a new feature called Aero Glass transparency. This makes the window borders and other elements on the screen semi-transparent, so you can see through them to the background. However, some users may find this effect to be disruptive or simply prefer a more traditional look for their desktop. If you fall into either of these camps, you can disable Aero Glass transparency with just a few clicks. Here’s how:

  1. Open the Settings app by pressing the Windows key + I on your keyboard.
  2. Click on Personalization.
  3. Click on Colors in the left-hand sidebar.
  4. Scroll down to the bottom of the page and turn off the toggle switch next to Transparency Effects.
  5. Close the Settings app and enjoy your new, non-transparent windows.
