1We have VDI in our company (cca. 50 Virtual Desktop Machines / Windows 10 / VMware Horizon View).
I have noticed that on all user machines process explorer.exe is using constantly cca. 20% of CPU (Thread shcore.dll!Ordinal247+0xc0 )
When I kill explorer.exe is all ok for several minutes, but then this problem appears again.
We have all latest Windows Updates on our VMs.
UPDATE 01.03.2018. -> Here is Screenshot from WPA for Analyze
UPDATE 05.03.2018. -> Here are the settings for Taskbar.

FIX 14.03.2018. -> Cursor Blink Rate setting

Best Answer
Under Control Panel -> Keyboard properties, the Cursor Blink Rate was set on "None" and after we changed it to somewhere in the middle -> problem is gone.
I don't know how/why, but this setting was problematic by us.
