Your best option is to format.

As Piper stated, something went astray in windows and it's better to format.

Here is some general info about kernal32.dll

What worries me is the error exists in to different instances 1) NIC properties 2) media app

If you still get kernal error messages after a complete format then look at memory/motherboard.
