Final answer:
To resolve network device issues after a driver update on Windows 10, the Driver rollback feature should be used to revert to the previous driver version.
Step-by-step explanation:
If you have a Windows 10 machine and the network device stops working properly after installing a newer version of the network adapter driver, the appropriate tool to use is the Driver rollback feature. This is built into Windows 10 and allows you to revert to the previous driver version that was working correctly. To roll back a driver, go to Device Manager, locate the network adapter, right-click it, choose Properties, go to the Driver tab, and then click on 'Roll Back Driver', if available. This is typically the first step in troubleshooting driver issues that arise after an update.
