So, the Hyper-V Manager stopped allowing me to open the settings on any virtual machine. It would just stay on “loading…”; the cancel button worked but the properties just would not show up.
So, I uninstalled and reinstalled all Hyper-V settings under the Control Panel “Turn Windows features on or off”. No change. The Hyper-V settings still would not load.
So, I checked the device manager. There was a yellow flag alert under one of the WiFi adapters with the message, “Windows is still setting up the class configuration for this device.”.
Okay? Sounds like the network subsystem for Windows got borked. <insert high-tech-sounding cause here>
Tried a disable/enable. No change.
So, I did a network reset. “Settings”, “Networks”, “Status”, scroll down to “Network Reset”.
Rebooted. Everything in Hyper-V works now.. You’d think there would be a more robust system for a feature many people use, right?
