Fix Desktop Window Manager high GPU
0Here's how to Fix Desktop Window Manager high GPU.
i. If you're experiencing high GPU usage due to Desktop Window Manager (dwm.exe) on your Dell laptop, here are some steps you can take to troubleshoot and potentially resolve the issue:
1. **Update Graphics Drivers**:
- Outdated or corrupted graphics drivers can sometimes cause high GPU usage. Visit the Dell support website and download the latest graphics drivers for your specific laptop model. Install the drivers and restart your laptop to apply the changes.
2. **Check for Windows Updates**:
- Make sure your Windows operating system is up to date. Sometimes, Windows updates include fixes for performance issues and compatibility problems. Go to Settings - Update & Security - Windows Update, and check for any available updates. Install any pending updates and restart your laptop if necessary.
3. **Disable Visual Effects**:
- Desktop Window Manager (dwm.exe) is responsible for rendering visual effects such as transparent windows, window animations, and taskbar thumbnails. Disabling these visual effects may reduce GPU usage.
- Right-click on the Start button and select "System."
- In the System window, click on "Advanced system settings" on the left sidebar.
- Under the "Performance" section, click on the "Settings" button.
- In the Performance Options window, select the "Adjust for best performance" option or manually uncheck specific visual effects that you can live without.
- Click "Apply" and then "OK" to save the changes.
4. **Reduce Hardware Acceleration**:
- Some applications and web browsers use hardware acceleration, which offloads certain tasks to the GPU. Disabling hardware acceleration in these applications may reduce GPU usage.
- For web browsers like Google Chrome or Mozilla Firefox, go to their settings/preferences and search for hardware acceleration. Disable it if enabled.
- In other applications, look for similar settings to disable hardware acceleration.
5. **Scan for Malware**:
- Malware or viruses on your system can sometimes cause abnormal system behavior, including high GPU usage. Perform a full system scan using your preferred antivirus software to check for any malicious programs and remove them if found.
6. **Check for Background Processes**:
- Other background processes or applications running on your laptop may be consuming GPU resources. Use Task Manager (Ctrl + Shift + Esc) to monitor and identify any resource-intensive processes. Consider closing unnecessary applications or processes to free up GPU resources.
7. **Reset or Reinstall Windows**:
- If none of the above steps resolve the issue, consider resetting or reinstalling Windows on your Dell laptop. This can help eliminate any software-related issues or conflicts that may be causing high GPU usage.
If you're still experiencing high GPU usage after trying these steps, it may indicate a hardware issue with your laptop's GPU. In that case, contacting Dell support or seeking assistance from a professional technician may be necessary.
