Bump - Windows manager + windows 10 + run dwm.exe on discrete gpu + force windows manager on discrete gpu. I hope this gets indexed and the messiah comes someday.

Posted by Bluenxd: “monitors shut down, 100% fan speed, dwm.exe”

Here it's: The Desktop Window Manager process has exited. (Process exit code: 0x0000042b, Restart count: 1, Primary display device ID: NVIDIA GeForce GTX 650) Not a major drama, as DWM restarts automatically. In this case, it's issues arising from wake up from hibernation, where device states are either mismanaged, or not correctly read in.

Now, my event viewer shows the below error: Faulting application name: dwm.exe, version: 10.0.19041.746, time stamp: 0x6be51595 Faulting module name: KERNELBASE.dll, version: 10.0.19041.2788, time stamp: 0x62e593d6 Exception code: 0xe0464645 Fault offset: 0x0000000000117cd2 Faulting process id: 0x3740 Faulting application start time ...

3. **Genuine BAR1 allocation issue:** The driver may be over-allocating BAR1 mappings, and while the system functions at lighter loads, heavy desktop workloads with 40+ DWM-registered processes may push BAR1 contention to a point that causes compositing stalls.

Can I force windows 10's Desktop Window Manager (dwm.exe) to run on my discrete Nvidia gpu? (Optimus - 860m + Intel 4600igpu) That intel igpu really...sucks. PS: no, it doesn't work if you try to use Nvidia's control pannel - the only option is to use "integrated graphics". Doesn't work either if you force the system to always use Nvidia chip in the same control panel. PS2: willing to tweak ...

Yea dwm.exe crashed even after bios restart with the 2133mhz ram profile. Whose support should i contact so i can find out what exactly causes this?

I checked the event viewer and found multiple instances of dwm.exe crashing with the event code '1000', this causes the nvidia drivers to in turn crash (or vice verca?).

I discovered that by degrading to a lower version of the graphic cards driver and the "Desktop Window Manager" would return to a normal state. I have also tried updating my driver ( or clean installation) with the latest drivers and experiencing the same high usage experience. The most stable driver working for me is version 517.48.
