Software Troubleshooting
Software Troubleshooting (23% of Core 2) covers diagnosing Windows, mobile, and security-related failures: boot problems, blue screens, malware, profile corruption, and application crashes. Questions are scenario-based — a symptom is described, and you pick the best diagnostic step, tool, or fix, usually in Windows 10/11, macOS, Linux, or mobile OS contexts.

What this domain covers
What to know about Software Troubleshooting
Be able to diagnose a described symptom and choose the least destructive fix: Safe Mode, msconfig, Event Viewer, System Restore, or ProfileList registry repair. The single most important thing is identifying what changed recently before recommending a reinstall.
Using Safe Mode, msconfig, and Event Viewer to isolate boot and driver failures
Repairing corrupt user profiles via Registry ProfileList and User Profile Service
Removing malware with Windows Defender, MSConfig, and System Restore rollback
Resolving application crashes, BSODs, and slow startups from third-party utilities
Watch out for
Common Software Troubleshooting exam traps
- ▸Choosing reinstall or reset before trying Safe Mode, System Restore, or disabling the suspect startup app.
- ▸Confusing CRITICAL_PROCESS_DIED causes — blaming hardware when a newly installed utility is the trigger.
- ▸Deleting a corrupt profile without backing up data or editing the ProfileList registry key first.
