Desktop Window Manager High Memory Usage Fix

Are you experiencing high memory usage with Desktop Window Manager? Let’s explore some potential fixes.

Understanding Desktop Window Manager

Desktop with multiple open windows

Desktop Window Manager (DWM) is a crucial component in Windows 10 and Windows 11 that manages the display of windows on your screen. Sometimes, you may encounter high memory usage by DWM, which can slow down your system. One way to fix this issue is by restarting the DWM process.

To restart the DWM process, press Ctrl + Shift + Esc to open Task Manager. Look for “Windows Explorer” in the Processes tab, right-click on it, and select “Restart.” This will also restart the DWM process and hopefully reduce memory usage.

If restarting the DWM process doesn’t work, you can try updating your graphics card drivers. Outdated drivers can sometimes cause high memory usage by DWM. Check the manufacturer’s website for the latest drivers and install them to see if it resolves the issue.
