A technician needs to identify a problematic device that is causing system instability in Windows 10. In Device Manager, the device shows a yellow exclamation mark. Without using any third-party tools, which action is the BEST next step to try to resolve the issue?
The best next step is to update the device driver. A yellow exclamation mark indicates that Windows has detected a problem with the device, and the most frequent cause is a missing, outdated, or corrupted driver. Updating the driver (either automatically through Windows Update or manually via Device Manager) often restores proper operation. Rolling back a driver is useful only when the problem began after a recent update. Disabling the device removes its functionality without fixing the root cause, and uninstalling it is a more drastic measure usually attempted after an update fails.
