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 am having the same issue on an HP ZBook 14u G5. UHD620 + AMD Radeon Pro WX 3100. Tried all "internet" solutions and still using 2.5GB.

    I hope someone can provide a solution.

    Hey guys, thanks for your inputs on this.

    Unfortunately, reverting back to an older driver didn't fix my issue. So I'm just updating every once a new intel driver is available, hoping that it might fix it.

    My machine has a Nividia Optimus, meaning the iGPU is always in charge of the display and dGPU does all the heavy lifting and simply adds the calculated results to the iGPU's buffer when necessary. So I'm curious if a desktop system with dGPU also experience this issue.

    I've made a batch file that kills DMW.exe upon booting up the system, and interestingly I did observe a difference. When DMW.exe is newly started, sometimes I see no memory leakage at all even after using my machine for 3 to 4 hours. When I DO NOT kill the DMW.exe, there is 100% guarantee that there would be memory leakage within the first 1 hour. I've tried to look into the memory address so that I could pinpoint the trigger program / service, but to no avail.

    Anyway, I've found a temporary solution. It's still a hassle but doesn't bother me as much. Not sure which party is to blame, MS or Intel but hopefully it'll get fixed soon.

    But do you still have an Intel CPU with an Intel HD? Its possible that this is still rendering anything non-intensive like your desktop and thus still causing a memory leak.

    Mine is not an Intel driver problem, as I am using an Nvidia Super 2080. The process grows to 7GB. So will there be any fix for this ?
