Now I'm lost as to what I can do to make it appear in Device Manager again.

However, after I had uninstalled and deleted the driver, the "Killer e2200 Gigabit Ethernet Controller (NDIS 6.30)" disappeared from the tab "Network adapters" in Device Manager. I proceeded by uninstalling the drivers, and as I did that I also got an option to delete the driver, which I did cause I had the driver ready to be re-installed in a folder on my desktop. I then tried to disable this feature on my network card, but still no connection. As I was enabling the hyper v extensible virtual switch protocol on my ethernet adapter, I lost connection to the internet. It all started when I tried to setup a virtual machine with Hyper-V. If this keeps appearing due to third-party or Microsoft Auto-Updates, see the related articles below.Okay, so I'll keep this as short as possible.
