“Windows is still setting up the class configuration for this device. (Code 56)” error
on Windows

Hello. My Windows PC has no Internet and I see the "Windows is still setting up the class configuration for this device. (Code 56)" error in Device Manager. What do I do?

Windows is still configuring the class settings for this device, says the message. (Code 56)" error is a relatively common issue that Windows users might encounter. This error message frequently appears when a network adapter installed on the system and a third-party VPN (Virtual Private Network) software conflict. The interaction between the VPN program and Windows' network setting procedure is the primary contributor to this problem.

This error is frequently seen when third-party VPN software obstructs the network adapter's normal setup and configuration. It may interfere with the class configuration procedure, preventing Windows from completing the device setup. Simply put, contradictory activities done by the VPN software cause the network adapter settings to become stuck.

Users have a number of alternative solutions at their disposal to address the "Windows is still setting up the class configuration for this device. (Code 56)" error and return their Windows system to regular operation. The removal of the third-party VPN software that is creating the issue is one viable line of action. Users may be able to solve the problem's core cause by removing the troublesome VPN.

The network adapter drivers[ref en-1] may need to be updated or reinstalled in order to fix the setup problems. Another method in overcoming compatibility issues is to keep Windows' operating system updated. Issues resulting from the interaction between the network adapter and the VPN software may be resolved by routinely updating the system with the most recent patches and updates.
