How to Solve Error Code 0xC000009A

There are several troubleshooting steps you can take to address error code 0xC000009A:

Run System File Checker (SFC) Scan

Open Command Prompt as an administrator and type the following command:

This utility scans your system for corrupted files and attempts to repair them.

Use DISM Tool

The Deployment Image Servicing and Management (DISM) tool can also help fix system file issues. Open Command Prompt as an administrator and run the following commands:

  • DISM /Online /Cleanup-Image /CheckHealth
  • DISM /Online /Cleanup-Image /ScanHealth
  • DISM /Online /Cleanup-Image /RestoreHealth

Update Drivers

Ensure all your device drivers, particularly those related to graphics cards and other peripherals, are up-to-date. You can use Device Manager (accessible through the Windows key + X menu) to check for driver updates. Alternatively, visit the manufacturer's website for the latest drivers compatible with your hardware and operating system.

Run a Virus Scan

Perform a thorough scan using a reputable antivirus program like Windows Defender or Malwarebytes to eliminate any potential malware infections that might be causing the error.

Check BIOS Settings

Access your computer's BIOS settings (usually by pressing Delete, F2, or another key during startup) and verify that all configurations are set correctly. Consult your motherboard manufacturer's documentation for specific instructions on accessing and modifying BIOS settings. If you are unsure about making BIOS changes, it is best to seek assistance from a qualified technician.

Perform System Restore

If the error appeared recently, try restoring your system to a point before the problem occurred. Access System Restore through the Start Menu, search for "Create a restore point", and follow the on-screen instructions.

Reinstall Windows

As a last resort, reinstalling Windows might be necessary if other solutions fail. Before proceeding, back up all important data to an external drive or cloud storage. You can download the latest Windows installation media from Microsoft's website: Windows 10 Download.
