Hi Ivan, Yes, I have managed to resolve the issue by disabling the WDDM driver as suggested by you in the other thread, Ubuntu 18.04.
Steps to do it: As a workaround on all of my affected machines I have used Group Policy Editor to set Local Computer Policy Computer Configuration Administrative Templates Windows Components Remote Desktop Service Remote Desktop Session Host Remote Session Environment Use WDDM graphics display driver for Remote Desktop Connections to DISABLED reference: https://forums.intel.com/s/question/0D70P000006K2n4SAC/dwmexe-high-cpu-one-core-on-target-system-after-remote-desktop-disconnect-on-windows-10-x64-1903-fully-patched?language=en_US I have also tried to update first the system and this updated the Windows to 1906 or 1909, but the problem was still there. I hope this helps other people as well.
