Intel graphics driver (as of has memory leak – fix (as of available

Windows[German]Brief note for people who run a Windows 10 with Intel processors of the 6th to 10th generation. If sporadic system crashes occur under Windows 10 (64 bit), a faulty Intel graphics driver newer than version may be the cause. The graphics drivers cause a memory leak in the Desktop Windows Manager. The problem is known since 2020, if my research is not deceiving. However, there has been a fix from Intel since Dec. 2021 in the form of the Windows DCH driver


Old bug from 2020?

While researching a memory leak in the Desktop Windows Manager, I came across reports that date back to 2020. As early as Sept. 5, 2020, there is this Microsoft Answers forum thread stating a memory leak in Desktop Windows Manager (dwm.exe) under Windows 10 version 2004.

The thread is 16 pages long and one solution said that an Intel graphics driver was the cause. The remedy was the post to uninstall the driver and install an older version.

The bug also seems to have affected users as late as March 2021, according to this Microsoft Answers forum post. Intel has this forum post from October 2020 that also addresses the problem. In November 2021, an Intel employee has come forward and reported that a beta driver 101.1121 fixes this issue.
