NOTICE: Microsoft put the functionality back with their Windows 8.1 Update 1.
Please use the system provided network profile manager from now on. This project is now deprecated unless Microsoft removes it again in the future.
I don't know what Microsoft was thinking.
They've removed the function to review all your WiFi connection settings in Windows 8.
I made this simple app under 20 mins, so that you can delete settings and prevent your machine from connecting to unwanted networks again.
It's very limited function-wise, but it gets job done.
You know the rule. If they removed what is essential, somebody's gonna have to make one him/herself.
