Symptom: All network adapters are missing from Windows Network Properties and do not appear when running ipconfig, but they still appear in Device Manager
Possible Solution: Netsh winsock reset. Executing this command will default network settings. After running this command, custom network settings such as static IP addresses and VPNs will likely need to be reconfigured.
1. Open a command window as Administrator (run as Administrator)
2. type netsh winsock reset
3. Restart the computer
After a restart, check Network properties or run ipconfig to verify the network adapters are back.
