We've seen some users reporting a high memory issue with the Desktop Window Manager on platforms like Reddit and other forums. Intel has launched an official driver update to address this issue. Read this article thoroughly to learn how to update the driver.

What Is Desktop Window Manager?

Desktop Window Manager (Dwm.exe) is a synthetic window manager that renders all of these effects in Windows: transparent windows, real-time taskbar thumbnails, Flip3D, and even high-resolution display support.

Rather than drawing their displays directly to your screen, applications write bitmaps of their windows to specific locations in memory. Windows creates a composite before sending all the windows on the screen to your monitor. Because Windows is composing and displaying the contents of each window, it can add effects such as transparency and window animations when layering windows.

Why Is Desktop Window Manager Using So Much Memory?

Usually, a desktop window manager uses 50-100 MB of memory and takes up 2-3% of CPU usage. When you open any windows or applications, high memory usage can occur because numerous processes are running. When memory usage gets high, your computer can slow down and even freeze without warning. In this case, the current high memory usage by the desktop window manager might be due to a bug in the Intel driver. Don't worry, Intel has released a new graphics driver update for your device.
