Unknown devices on Windows 10

I noticed that I have unknown devices in my Device Manager on Windows 10 machine:

Where do they appear from? What to do with them?

EDIT1:

Device by connection view:

Device instance path and hardware ids:

ROOT\NET\0001 ptun0901

ROOT\NET\0002 ptun0901

ROOT\NET\0003 ptun0901

...

EDIT2:

My mainboard is Gigabyte Z390 AORUS PRO. Installed the following from CD:

I uninstalled all unknown devices and will try to reboot:

but unknown device did not disappear.

As per your information from the hardware IDs, the many “Unknown device” instances with the problems (yellow triangle) are TAP-Win32 virtual network interfaces. They are often using with VPN software like OpenVPN. You indicate you removed some VPN software lately. It apparently only removed the TAP-Win32 driver without removing the virtual network interfaces.

You already succeeded in removing all the broken virtual network interfaces.

The remaining device, “SMS/MMS”, is not broken and working as designed. The driver developer just neglected to define its device category, so it ended up in “Other devices”. This is not a problem in any way. If you want further information on this device, you should check its hardware IDs like before as well as the associated drivers on the “Driver” property page. Others on the internet associate this device with a paired Bluetooth phone.
