Desktop Window Manager (DWM) handles graphical effects in Windows, and high GPU usage can stem from corrupted files, outdated drivers, or intensive visual settings. This guide offers step-by-step solutions to resolve the issue efficiently.
Check for System and Driver Updates
- Open Settings and select Update & Security.
- Install all pending Windows updates to patch known bugs.
- Visit your GPU manufacturer's support page to download the latest graphics driver—install it after uninstalling the old one via Device Manager.
Adjust Visual Effects Settings
- Type "*" in the Run dialog to open System Properties.
- Go to the Advanced tab and click Settings under Performance.
- Select "Adjust for best performance" or customize by disabling effects like transparency and animations.
- Apply changes and restart your computer.
Disable Transparency and Animations
- Navigate to Settings, then Personalization, and choose Colors.
- Turn off "Transparency effects" to reduce GPU load.
- Disable animations in Ease of Access settings by toggling "Show animations in Windows" off.
Monitor and Manage DWM Process
- Press Ctrl + Shift + Esc to launch Task Manager.
- Locate "*" under the Processes tab—observe its GPU usage.
- If usage spikes, end the task briefly; Windows will restart it automatically to reset potential glitches.
Perform Advanced Diagnostics
- Run System File Checker: Open Command Prompt as admin and execute "sfc /scannow".
- Use Performance Monitor to analyze GPU usage trends over time.
- For persistent issues, reset Windows graphics settings via Troubleshoot in Settings.
Consistently applying these steps optimizes system performance. If problems persist, evaluate hardware limitations or seek professional diagnostics.
