  1. Desktop Window Manager high memory usage


    My Desktop Window Manager is normal upon boot but some time after I open up games it goes and stays up high. This is one example:It's not as bad as yesterday where my memory went up to 90% and it really never goes down even after closing my game. Sometimes it has caused my game to crash and states that I have run out of memory. After restarting though, it goes back to normal but I can't go on restarting my laptop over and over after playing a game just to make it go down.Can anyone help me with this? Thanks.Specs:CPU: i7-9750HGPU: GTX 1660ti-mobileRAM: 16gb 2x8OS: Windows 10 x64Version: 21H1

    :)

  3. Desktop Windows Manager High Memory Usage

    Hi Jay,

    This high memory usage could have happened due to multiple application running. If Windows 10 has features that are not working properly, we suggest that you run the System File Checker tool and the Deployment Image Servicing and Management tool to scan
    and correct any issues. System File Checker (SFC) is a built-in tool in the operating system. SFC checks for system file corruption. Deployment Image Servicing and Management (DISM) is a command-line tool that can be used to service a Windows image or to prepare
    a Windows Preinstallation Environment image.

    Kindly follow the steps in this article posted by
    ZigZag3143 (MS -MVP)
    to perform SFC and DISM:
    System file check (SFC) Scan and Repair System Files & DISM to fix things SFC cannot.


    Update us with the result so we can further assist you.

    Desktop Window Manager high memory usage

    Desktop Windows Manager high GPU usage persists

    Several individuals have reported Desktop Window Manager (dwm.exe) using unrealistic amounts of GPU for video playback, gaming, or any high graphics intensive activity. Here is a list of just a few of the many requests for support on this issue:

    Example 1

    Example 2

    Example 3

    Example 4

    Example 5

    It has been a few years now that this problem has been reported, are there any accepted fixes. From what I gather, even those individuals with serious graphics cards are vulnerable to dwm.exe dominating their available GPU. I myself report this issue, even
    on games and design software with the settings at a minimum. For example, Java will be using ~45% of the available GPU, whereas dwm.exe takes up the remaining ~55%. As stated previously, the result is the entire system halting, not just the game. The mouse
    will take a few seconds to stutter across the screen, and task manager will take 5+ seconds to even appear.

    There have been many suggestions and no results. Is that Microsoft's consensus then? Thank you ahead of time.
