💻 Usage

The script presents an interactive menu with the following options:

1. Quick Status Check (DISM /CheckHealth)

   • Fast verification of system image integrity
   • Recommended as first diagnostic step

2. Detailed Scan (DISM /ScanHealth)

   • Thorough system image analysis
   • May take several minutes to complete

3. Repair System Image (DISM /RestoreHealth)

   • Attempts to repair corrupted system files
   • Downloads replacement files if needed
   • Can take 15-30 minutes depending on system state

4. System File Checker (sfc /scannow)

   • Scans and repairs corrupted Windows system files
   • Recommended after DISM repairs

5. System Update Repair

   • Use after Windows Update troubleshooting has failed
   • Requests confirmation before resetting update caches
   • Backs up cache folders and attempts service recovery on failure
   • Does not change proxies, drivers, or service startup settings

6. Repair image, then system files

   • Runs DISM /RestoreHealth, then sfc /scannow after successful image repair
   • Stops if DISM fails or requires a restart before continuing
   • Does not include Windows Update repair operations

7. Restart System - Requests confirmation before restarting

8. Restart to firmware settings - Requests confirmation; requires firmware support

9. Help - Describes available operations

Press 0 to exit and return to the calling terminal.

⚠️ Important Notes

• Always backup important data before running system repairs
• Requires administrator privileges to execute repairs
• Save your work before confirming a restart
• Windows Update repair temporarily stops update services and retains cache backups
• Internet connection required for downloading system files during repair
• The sequential repair mode follows Microsoft's recommended execution order for optimal results

🔧 Technical Details

The script performs the following technical operations:

Core Repair Commands (Sequential Mode)

• DISM RestoreHealth: Repairs Windows component store using Windows Update
• SFC scannow: Verifies and repairs individual system files

DISM /CheckHealth and /ScanHealth remain separate diagnostic options.

Windows Update Repair Operations

• Service management (stop/start) for:
  • Background Intelligent Transfer Service (BITS)
  • Windows Update Service
  • Cryptographic Services
• Cache folder backups with unique names
• Command-result checks and service recovery attempts on failure

📋 Command Execution Order

The sequential repair mode follows Microsoft's recommended order:

1. DISM /RestoreHealth - Repairs the Windows component store
2. sfc /scannow - Runs after successful image repair

If DISM fails or requires a restart, resolve that condition before running SFC.

🔍 Troubleshooting

If you encounter issues:

1. Ensure you're running as administrator
2. Check internet connectivity for file downloads
3. Verify Windows Update service is accessible
4. Check system drive for sufficient space (at least 2GB free recommended)
5. Review logs in %windir%\Logs\DISM\dism.log
   • Also review the per-run log path printed by the script
   • Exported [SR] entries include historical SFC details, not just current-run errors
6. If sequential repairs don't resolve issues, try running individual commands separately
7. For persistent corruption, consider Windows in-place upgrade or system restore
