You’ll want to grab Intel DCH driver 220.127.116.111 if your Windows 11 or Windows 10 device is acting up. The patch is now available for users around the globe with Intel’s 6th generation processors or newer, and it aims to resolve issues with the Desktop Window Manager.
Desktop Window Manager provides taskbar thumbnails, app windows, animations, high-resolution monitors, and other visual effects in the operating system.
Windows’ Desktop Window Manager appears in Task Manager as “DWM.exe” or “Desktop Window Manager”. Since DWM plays such an important role in the graphical user interface of Windows 10, it is impossible to disable it. In recent builds of Windows 10/11, the role of DWM has increased even more.
Most of the time, Desktop Window Manager should run smoothly in the background and won’t use too much of your device’s processing power. On most devices, Desktop Windows Manager uses less than 100 MB of RAM and 2-8 % of the CPU. That’s good enough for smooth performance.
If your Intel driver package or the OS itself contains a bug, you may see a high utilization of resources. If this is the case, Desktop Window Manager will consume more RAM or CPU than you think it should, and it may cause stability problems with Windows 10 or Windows 11.
As Microsoft works on multiple fixes for Windows 11’s performance issues, Intel has published a new driver update that fixes a critical stability issue in Desktop Window Manager (DWM) on devices with Intel integrated graphics.
Intel’s changelog notes that Desktop Window Manager (DWM) on 6th generation Intel Core Processors through 10th generation Intel® Core Processors has been improved in stability.

As part of the December 2021 Update, Intel has also fixed various issues with its graphics driver.
Intel says it improved performance when playing Halo: Combat Evolved Anniversary in classic graphics mode. Several bugs, which caused frequent crashes and lags while playing certain games, have been fixed in this update.
Affected games include Battlefield 2042 and FIFA 21. The graphics anomalies found in Shadow of the Tomb Raider and Rise of the Tomb Raider have also been addressed by Intel.
How to get Intel’s latest driver on Windows
