If a customer experiences a blue screen after updating a wireless adapter, what should you do first?

When a customer experiences a blue screen after an update to a wireless adapter, rolling back the device drivers in Safe Mode is the best first step. A blue screen, or BSOD (Blue Screen of Death), typically indicates a severe issue, often caused by hardware or driver incompatibilities. After an update, it’s possible that the new drivers are unstable or incompatible with the system's current configuration or other drivers.

By accessing Safe Mode, you can operate the system with minimal drivers and services running, which reduces the chance of further issues while attempting to fix the problem. Rolling back the drivers effectively reverts the wireless adapter to its previous stable state, which may resolve the blue screen issue immediately. This process tends to be quicker and less costly than replacing hardware and does not involve the complexities of testing the device on another computer or diagnosing deeper system issues that may not be related to the adapter.
