Recently my laptop started stuttering and found that Windows Desktop Manager (dwm.exe) was spiking the integrated Intel GPU in my laptop causing the stutters (laptop also has GTX 1650 GPU). Scrolling down a website could cause spikes and laptop is close to unusable. I reset the PC to factory installation, tried pausing Windows updates but it still updated to 20H2 feature update and some security updates, too. MUCH worse when plugged into external monitor, but even without the laptop stutters. Not sure why factory settings don't work, unless some Windows update I can't stop is the true problem. I uninstalled the 20H2 update once, problem seemed better but came back. Even with pausing updates I check update history next day and Windows seems to sneak some stuff in, so hard to tell what's installed at any moment. May need to reset and stay off network to test absolute factory conditions. I can disable iGPU but then dwm.exe does similar on NVidia 1650 GPU, though not 100% usage but still causes stutters.
Any ideas? Any chance a hardware issue could be causing this?
