Thanks for joining the Graphics community.
The drver dwm.exe assists with graphics and the Aero interface, however, it should not create any performance issues.
I would recommend testing with customized drivers from your computer manufacturer, as I have noticed that your system includes Intel(R) graphics and AMD Radeon graphics. Try uninstalling any graphics driver Intel - AMD from control panel, then obtain customized versions here: MSI USA - Computer, Laptop, Notebook, Desktop, Mainboard, Graphics and more
Thanks for your solution.
I uninstalled the intel driver and thereafter installed the customizid MSI intel Driver.
It works like a charm!
You are welcome. I am glad to hear the system is working now.
