How to Fix Error Code 0xC0000194

  1. Boot into Safe Mode

    If you don't see the Advanced Boot Options, you may need to interrupt the startup process three times to trigger Automatic Repair. From there, go to Troubleshoot > Advanced Options > Startup Settings > Restart, then choose Safe Mode.

  2. Disable Non-Microsoft Services

  3. Perform a Clean Boot

    After clean boot, the deadlock should be gone. If so, enable services one by one to identify the culprit.

  4. Run System File Checker (SFC)

    Do not close the command window until the scan is complete. This may take several minutes.

  5. Check for Driver Conflicts

    If Windows doesn't find a driver, visit the manufacturer's website to download the latest version.

  6. Use Windows Memory Diagnostic

    Back up your data before running memory diagnostics as a precaution.

  7. Check for Malware

    Ensure your antivirus definitions are up to date before scanning.
