When I access another Windows 10 PC via remote desktop and then exit the remote desktop session, the CPU load goes up. It is DWM.EXE that causes it.
What I did to exclude other causes:
- scanned for viruses (yes, DWM.EXE is the original one from MS)
- made sure no magnifier was active (Google proposed this)
- made sure no screen saver is active and nothing else is on my lock screen
- made sure the gfx driver (Intel integrated) is up to date
dism /online /cleanup-image /checkhealth
dism /online /cleanup-image /scanhealth
chkdsk c: /f
do not show any problems.
Today I tried a second system as RDP target: Same problem! Could this be a bug? Can anyone else please try it, too? I don't know since when the problem occurs. Could be since 1903 (this is the version I use on both systems).
This is how it looks when I log the CPU loads:
