How to Handle the Unknown Hard Error Message During Windows 10 Shutdown?

During the computer's shutdown process, an "unknown hard error" message appears. For now, I have paused operations to avoid forcing a shutdown or restart. How should I proceed to systematically diagnose the cause and safely resolve this issue?

    Go to Settings > Update & Security > Windows Update.

    Install any pending updates and restart the system.

    Sometimes, updates resolve underlying system errors.

    Run the sfc /scannow and chkdsk /f commands in Safe Mode to check and repair system files and disk errors.
