Windows 10 and the faulty network adapter

Hi sysadmin !

Today I wanted to share a small bug I encountered, and how to solve it.

After all the update, if you lost all your network connection, and in your device manager they are all yellow in error, please check the status of them;

Network Adaptor error: Windows is still setting up the class configuration for this device. (Code 56)

3-1

If that happen to you, any new devices you will try to install will fall into the same state.

The Windows update will try to reinstall the driver, but will fail.

The recovery step is easy, check your VPN software installed, one is not Windows Ready for that build.

In my case it was CheckPoint VPN

Uninstall and the bug disappear live, no reboot necessary !
