You don't have a driver for the "Other devices > Unknown device"
Open device manager, right click on the "Other devices > Unknown device", select properties, Details tab - Hardware ID-
select first Value line, Right click - copy
Paste it here
Additionally to the above have you tried, my suggestion re Avast
It has something of a reputation for slow down on 10
Not that this is limited to Avast.
It applies to many other third party AV apps
1. The cause MAYBE Avast
I suggest you try as a first step uninstalling it and use the included Windows Security centre
This tip alone solved most of my problems. Holding onto the other ideas as needed. Many thanks.
Pleased to have helped - cheers and thank you for the appreciation.
