dwm.exe high memory usage normal?
Whenever I check my task manager periodically I notice the dwm.exe process (Desktop Window Manager) always uses lots of memory. I searched around and found that 30-50 MB RAM usage is normal but mine typically shows 200+ MB RAM being used. And it never goes down, even when I close all open windows and programs in the taskbar. I thought the amount of RAM used for dwm.exe was determined by how many open windows I had. In fact, closing windows can barely increase dwm.exe RAM use.
I read it can be affected by graphics drivers but I'm always up to date on the Nvidia drivers for my video card. I have all the latest Win 7 64 updates. If I change the Aero theme to Basic then it releases the memory.
Is it normal to use this much memory? Why doesn't it ever release the memory after I close the windows? Everything else seems to be working fine on my pc.
