How to Fix Error Code 0xC0000145

  1. Boot into Safe Mode

    If you cannot access Safe Mode, you may need a Windows installation USB or DVD to proceed.

  2. Run System File Checker (SFC)

    Do not interrupt the scan. It may take 15-30 minutes.

  3. Run DISM to Repair System Image

    Ensure your PC has a stable internet connection for DISM to download necessary files.

  4. Perform a Clean Boot

  5. Update or Roll Back Faulty Drivers

    If unsure, focus on display, network, and storage drivers.

  6. Use System Restore

    This will not affect your personal files but may remove recently installed programs.

  7. Reset or Reinstall Windows

    Back up your data before resetting. If you cannot boot, use a Windows installation media and select 'Repair your computer' > 'Troubleshoot' > 'Reset this PC'.

Frequently Asked Questions

What does error code 0xC0000145 mean?
It is a Windows boot error indicating that a critical system application failed to initialize. This can be due to corrupt system files, faulty drivers, or damaged Windows components.
Can I fix error 0xC0000145 without losing data?
Yes, most fixes like SFC, DISM, clean boot, and System Restore do not delete personal files. A Windows reset with 'Keep my files' also preserves your data.
How do I boot into Safe Mode if Windows won't start?
Interrupt the boot process three times: turn on your PC, and when you see the Windows logo, hold the power button to force shutdown. Repeat three times; on the fourth boot, you'll see 'Automatic Repair'. Click 'Advanced options' then 'Troubleshoot' > 'Advanced options' > 'Startup Settings' > 'Restart' and press F4 for Safe Mode.
What if SFC says it cannot repair the files?
Run DISM first to repair the system image, then run SFC again. If DISM fails, you may need to use a Windows installation media to perform a repair install.
Do I need a product key to reinstall Windows?
If you're resetting via built-in recovery, you don't need a key. If you reinstall from media, your digital license (linked to your Microsoft account) should activate automatically, but you may be prompted for a key.
