How to Fix CONFIG_INITIALIZATION_FAILED (0X00000063) BSOD on Windows 10 & 11

The CONFIG_INITIALIZATION_FAILED (0X00000063) Blue Screen of Death (BSOD) is a critical error that can occur in Windows 10 and 11, often leading to system crashes or unexpected shutdowns. This error typically appears when the operating system fails to properly initialize its configuration settings during startup. If you’re experiencing this issue, don’t worrythis guide will walk you through identifying the cause and applying effective fixes.

What Causes CONFIG_INITIALIZATION_FAILED (0X00000063)?

The error usually stems from corrupted system files, faulty hardware drivers, or issues with Windows configuration. Common causes include:

  • Corrupted system files due to improper shutdowns or malware.
  • Outdated or incompatible device drivers (especially graphics or storage drivers).
  • Faulty RAM or hard drive errors.
  • Conflicts with recently installed software or updates.
  • Corrupted Boot Configuration Data (BCD) during Windows updates.

How to Fix CONFIG_INITIALIZATION_FAILED (0X00000063)

Method 1: Run System File Checker (SFC) and DISM

Corrupted system files are a leading cause of this error. Use Windows’ built-in tools to repair them:

  • Open Command Prompt as Administrator:
    • Press Win + X, then select Terminal (Admin) or Command Prompt (Admin).
  • Run the following commands one by one, pressing Enter after each: 
    DISM /Online /Cleanup-Image /RestoreHealth
    sfc /scannow
  • Wait for the process to complete (it may take several minutes). Restart your PC afterward.

Method 2: Check and Repair Disk Errors with CHKDSK

If file system corruption is suspected, run CHKDSK to scan and repair disk errors:

  • Open Command Prompt as Administrator (as described above).
  • Run the following command: 
    chkdsk C: /f /r /x

    (Replace “C:” with your system drive if needed.)

  • If prompted, confirm to schedule the scan for the next reboot. Restart your PC.
  • After rebooting, check for any error reports in Event Viewer (Win + X > Event Viewer).

Method 3: Update or Reinstall Problematic Drivers

Outdated or conflicting drivers (especially graphics or storage) can trigger this BSOD. Heres how to address them:

  • Open Device Manager by pressing Win + X > Device Manager.
  • Expand categories like Display adapters, Storage controllers, or System devices. Look for devices with a yellow warning icon (indicating issues).
  • Right-click the problematic device and select Update driver, then choose Search automatically for drivers.
  • If no updates are found, try rolling back the driver:
    • Right-click the device > Properties.
    • Go to the Driver tab and click Roll Back Driver (if available).
  • If the issue persists, download the latest driver from the manufacturers website (e.g., NVIDIA, AMD, or your motherboard/CPU brand).

Method 4: Repair Boot Configuration Data (BCD)

Corrupted BCD can cause initialization failures. Use these steps to repair it:

  • Boot from a Windows installation USB (if you dont have one, create one using another PC with the Windows Media Creation Tool).
  • Select Repair your computer > Troubleshoot > Advanced options > Command Prompt.
  • Run these commands one by one: 
    bootrec /fixmbr
    bootrec /fixboot
    bootrec /scanos
    bootrec /rebuildbcd
  • Restart your PC after completing the process.

Method 5: Test for Hardware Issues (RAM or Hard Drive)

Faulty RAM or a failing hard drive can cause this error. Test them with these steps:

  • Test RAM:
    • Use Windows Memory Diagnostic: 
      mdsched.exe

      (Run the tool and follow on-screen instructions to check for errors.)

    • For thorough testing, use third-party tools like MemTest86.
  • Check Hard Drive Health:
    • Open Command Prompt as Administrator and run: 
      wmic diskdrive get status

      (Look for “OK” under the Status column. If it says “Pred Fail,” your drive may be failing.)

    • Use manufacturer tools like Western Digital Data Lifeguard Diagnostic or SeaTools for HDDs.

Method 6: Perform a Clean Windows Installation (Last Resort)

If all else fails, a clean install may be necessary. Back up your data first:

  • Download the Windows Media Creation Tool.
  • Create a bootable USB and select Custom: Install Windows only (advanced) during setup.
  • Choose to keep personal files and apps if prompted, or back them up manually.

FAQ About CONFIG_INITIALIZATION_FAILED (0X00000063)

Q: Will this error delete my data?

No, the BSOD itself doesnt harm your files. However, if its caused by a failing hard drive, back up important data immediately.

Q: Should I replace my RAM or SSD if this happens?

Only if hardware tests (like MemTest86) confirm errors. Otherwise, drivers or software fixes may resolve the issue.

Q: Can third-party tools fix this error faster?

While some tools claim to fix BSODs, Windows built-in utilities (SFC, DISM, CHKDSK) are reliable and safer for most users. Avoid untrusted software.

Q: Why does this happen after a Windows update?

Updates can sometimes corrupt system files or drivers. Rolling back updates via Settings > Update & Security > Recovery may help, but ensure you have the latest stable version.

Q: Is this error related to overclocking?

Yes, if youve overclocked your CPU/GPU, revert settings in BIOS or Windows to default. Overclocking instability can trigger BSODs like this one.

Final Notes

The CONFIG_INITIALIZATION_FAILED (0X00000063) error is usually fixable with the steps above. Start with SFC and DISM, then progress to hardware checks if needed. If the issue persists after trying all methods, consult Microsoft Support or a local technician for further diagnosis.

For future prevention, avoid abrupt shutdowns, keep drivers updated, and run regular disk checks (chkdsk) to maintain system stability.
