  1. Desktop Window Manager dwm.exe high RAM usage


    Recently I felt a big performance decrease on my pc.

    My configuration:

    i3-8100

    GTX1660Ti

    8Gb RAM

    I have 2 screens:

    1 1680x1050

    2 1920x1080

    When I start Task Manager I often see 94% RAM usage and the first reason is Desktop Window Manager. It uses neraly 5Gb of memory.
    If I kill this process it starts to use about 300Mb and then slowly rises to previous values.

    I use Wallpaper Engine and tried to disable it, but got no result.

    I also see dwm using more than 10-15% of CPU and GPU. I've done almost everythnig I found on web such as updating drivers or something but nothing's changed.




    PLEASE don't write about scanning for viruses, buying new memory and etc. I need real help and want to improve performance of my pc.

    :)

  2. Desktop Window Manager High GPU Usage in Windows 10

    Hey everyone,

    i got the same Problem since two days. My PC configuration is a Gigabyte 2070 Super 8GB and a Ryzen 7 3700X and ive got every update from Windows and Geforce experience. I am wondering why Windows doesnt said anything to this Problem after seeing this thread
    being 20 Pages Long. Does anybody tried These Solutions
    https://appuals.com/fix-desktop-window-manager-high-cpu-usage-dwm-exe/
    ?

    First i thought the cause is Google Chrome because it made high gpu and Volt usage too but after an uninstall the Problem was still there.

    Is there any Suggestion how to solve the Problem. If this link is working please tell me.

    Hi Anthony,

    Open the Settings App (gear icon on your Start Menu)

    Go to Privacy - Background Apps

    Turn everything off on that page

    Restart your PC
