  1. Why is dwm.exe (desktop window manager) using so much ram?


    The only programs I have open are zoom, chrome and discord. I opened task manager to see that dwm.exe was using about 2800 mb of ram. I have 16gb in total so it wasn't that much of an issue but I think this is out of the ordinary.

    Desktop Window Manager is not listed under services.msc. How can I get DWM back? Thank you.

    Why is dwm.exe (desktop window manager) using so much ram?

    Finding username DWM-1 on the task manager

    Hi mik07, Welcome to 10F! *Smile

    Out of curiosity I looked at mine and also found a dwm-1 listed under user name:

    The next thing I did was run this CMD: C:\Users\(your user name)>tasklist /v in a regular CMD prompt, the /v switch is for verbose, and I came up with:

    So I started reading up on this dwm-1 and from what I can tell the desktop windows manager (dwm) has a lot of responsibilities when a computer is being used and it is a way for the dwm to differentiate between the services it provides. DWM.exe is the parent and DWM-1, 2, 3, and so on are the children.

    In my case dwm-1 is running the notification window that slides out from the right side of the desktop. From this article:
    It looks like as long as you see local or console in the session name your okay, but if you see remote logon via RDP (Remote Desktop Protocol) you'd better check into that especially if you weren't expecting a remote log-on.
