  1. dwm.exe 100% CPU load


    I have this Windows 10 (1903 with latest updates) computer that I log on to by using Remote Desktop.

    As long as I am logged in, everything is fine. As soon as I disconnect and the user remains logged on, Desktop Window Manager (dwm.exe) jumps to 100% CPU usage. (The dwm.exe instance running in the context of that user).

    This gets to the point where, after some time, the computer becomes unresponsive and I cannot log in anymore at all.

    I have tried re-installing Windows and using different user accounts created from scratch. It always comes back.

    The computer is a virtual machine running on Hyper-V.

    What can I do?

    :)

    DWM uses lot of CPU

    Thanks for your answer and help!

    I performed the suggested actions, but unfortunately no result. I just repeated the troubleshooting but no results.

    This morning the same occurred DWM took lots of CPU and UI is slowing down to unworkable. It took 10-15 min and then is was normal again.

    Is there Anything I can Do?

    Thanks,

    Paul
