it's a clean installation of windows 10
and in the meantime I only installed programs from the mobo and gpu CDs.
+ steam and origin

But in a task manager is WMI Provider Host at the first place.
always uses from 1% to 60% CPU

after little research i found this: cimwin32.dll could be cause of WMI problem.
