Windows 10: Unknown stuff in device manager

I know it looks like i'm referring to literal unknown devices in device manager, but i am not. Under disk drives, there is a device called "xvd" and I have no clue what this is. If i unplug my external hard drive, and all my USB devices, it is still there. it says it's on the USB bus but it's there even when there is nothing plugged into the USB ports. It says the driver is from 2006, but this is a 2014 computer.


here is a screenshot




i haven't seen this before today, either

X800 GTO2 = Unknown Device

I flashed the BIOS on my X800 GTO2 last night and it is listed in the Device Manager as an Unknown Device. Is this normal?

 

Network devices listed under Unknown in Device Manager


I have a Dell Inspiron M731R laptop upgraded from Windows 8.1 to Windows 10 Home 64-Bit that suddenly quit connecting to the home network. Was using wireless, so switched to an Ethernet cable, but still no luck. I just discovered that ALL of the network-related devices are now listed under an "Unknown" tab in the Device Manager. A check of properties of each item in that folder says they are all working properly, but that obviously isn't the case. I tried uninstalling each of the 4 items, but when they are recognized again they still show up under the Unknown tab. Any suggestions would be welcome.
