Desktop Windows Manager (DWM) memory leakage in Windows 10 (Version 2004).

The infamous dwm.exe hogging lots of memory. FYI this is not a specific program issue. It just happens with any programs, activities randomly.

I'm getting really tired of killing dwm.exe every so often so that it will release the occupied memory. When is this going to be fixed? Is this ever going to be fixed even?

    I reported the problem here:

    https://community.intel.com/t5/Graphics/BUG-dwm-exe-uses-memory-leakage-with-Intel-HD-Graphics-630/td-p/1222297

    many have it, but Intel is unable to reproduce it, so it's up to MS :(

    Until then yyou can use these temporary "fixes":

    • roll back driver to 26.20.100.7985 (that is my solution and disable automatic graphic driver updates)
    • restart the comouter instead using fast startup through shut-down
    • restart the dwm.exe in task-manager

    Hi, saw this post on the search for myself. Had the same problem. 

    In case you didn't find a fix for yourself. I want to share my solution:

    In my case, I updated Windows 10 to 2004 and by doing so had a driver problem with my Intel HD Graphics 630, which lead to an install of the latest version. I did that all for the new GPU scheduling feature and thought that was the problem.

    After many researches on the web I found a post on Reddit, where someone commented the solution that worked for me. The Intel drivers caused a memory leak for dwm.exe. I had to uninstall it and install an older version of the drivers from early 2020.

    Here to the comment on Reddit which helped me.

    It is an intel problem, I saw this issue happening from the latest version. I didn't upgrade my nvidia driver tho.
