Windows Troubleshooting Skill

Systematic diagnosis for Windows issues.

Workflow

  1. Symptom Mapping: Recent changes? Exact error?
  2. Resource Check: CPU/Mem (get-process-list), Disk (check-disk-space).
  3. Log Deep Dive:
    • Get-WinEvent -FilterHashtable @{LogName='System'; Level=1,2} -MaxEvents 50
    • Look for Event IDs: 1001 (BugCheck), 6008 (Dirty Shutdown), 7031 (Service crash).
  4. Hardware/Drivers: Get-PnpDevice | Where Status -ne 'OK'.
  5. Corruptions: sfc /scannow, dism /online /cleanup-image /restorehealth.

Rules

  • Never guess. Use logs.
  • Isolate: disable 3rd party services (Clean Boot) if cause is unknown.
  • Document findings: Root Cause, Evidence, Fix, Prevention.
