@Sammy2 this here gets rid of the Killer application support and the driver it basically tells Windows that the Killer E2200 chip is a Atheros AR8161 instead which is it's sibling but u doesn't really see a lot.
Back when I used this I had zero issues and today the girl special in my life have no issues running with this driver on a small ITX system I build for her with the money I had at the time and still runs today.
Do my issues look to be typical for the Killer Application? I never use that dam thing anyhow.
