A user is unable to start a computer following a failed Windows 10 update. When trying to start the computer, the user sees a blue screen of death. Which of the following steps should a technician…

Performing a safe mode boot allows the operating system to start with a minimal set of drivers and services, which can help diagnose if the blue screen of death is caused by conflicting third-party software or faulty drivers installed during the update. If the computer boots successfully in Safe Mode, it indicates the issue lies with a non-essential driver or application.

Running System Restore is a potential solution, but it is usually performed after diagnosing the issue, often initiated from Safe Mode or Windows Recovery Environment, not as the very first diagnostic step.

The 'Last Known-Good Configuration' option is primarily available in older Windows versions (up to Windows 7) and is not a common or direct option in Windows 10 for post-update boot issues.

Resetting BIOS settings is generally used to troubleshoot hardware-related boot issues, not typically a failed Windows update which is a software problem.
