dwm.exe high CPU usage

[jxing2]

after i install another 970 to build sli in my system and tried to use asus AI Suit3 to overclock my cpu, the thing called dwm.exe shows up and keep eating 20%+ of cpu usage. after my research this thing seems cannot shut down. is there any way to reduce the cpu usage?

First, I'll briefly explain what dwm.exe is. DWM, or the Desktop Window Manager, is what renders applications in Windows. If you have alot of applications open, or are using a DWM extension such as Aero Glass, this can severely increase your CPU usage.

 

Here's my question - What OS are you using and do you use any 3rd party DWM extensions (that you are aware of)?

hopefully this link can be of some assistance as well (for win 10)

win10 64bit, and i just reinstalled win10 before i overclock the cpu, so pretty sure there is no extensions

Sorry, had to go to sleep. Have you tried restarting the computer? I'm not too sure why DWM would use so much CPU.
