This guide will walk you through simple and effective solutions for resolving this error. Each step is explained clearly, so even users with minimal technical knowledge can follow along.

By the end, you should have a better grasp of what causes this error and how to fix it properly. Let’s get started with some quick checks before diving into troubleshooting.

Remember, patience and careful following of instructions are key to avoiding further issues.

Quick Note: Prerequisites and Preliminary Checks

Before proceeding with fixes, ensure the following:

  • Backup Important Data: Although the steps here are generally safe, it’s wise to back up your files to prevent data loss.
  • Check for Recent Changes: Identify if you installed new software, updates, or hardware before the error appeared. This can help pinpoint causes.
  • Ensure Windows is Updated: Sometimes, system updates include fixes for errors. Go to Settings > Windows Update and check for any pending updates.
  • Have Administrator Access: You will need admin rights to perform some troubleshooting steps.

Step 1: Restart Your Computer

This may sound basic, but many errors resolve after a simple restart. Restarting clears temporary files and resets system processes that might cause conflicts.

To restart:

  1. Click the Start button.
  2. Select the Power icon.
  3. Choose Restart.

Once your PC restarts, check if the error persists.

Step 2: Run System File Checker (SFC) Scan

The System File Checker tool scans Windows system files and repairs corrupted or missing ones that could cause the error.

Follow these steps:

  1. Press Windows + S and type cmd.
  2. Right-click on Command Prompt and select Run as administrator.
  3. In the Command Prompt window, type the following command and press Enter:
sfc /scannow

This process may take several minutes. Once completed, it will report if any corrupted files were fixed.

Restart your PC and see if the error is resolved.

Step 3: Use DISM Tool to Repair Windows Image

If the SFC scan didn’t fix the issue, the Deployment Image Servicing and Management (DISM) tool can help repair deeper system image problems.

Here’s how to use it:

  1. Open Command Prompt as administrator (see Step 2).
  2. Type the following commands one by one, pressing Enter after each:
DISM /Online /Cleanup-Image /CheckHealth
DISM /Online /Cleanup-Image /ScanHealth
DISM /Online /Cleanup-Image /RestoreHealth

These commands check for corruption and repair the Windows image if needed. The process may take some time.

After completion, restart your computer and check if the error still appears.

Step 4: Update or Reinstall Problematic Drivers

Outdated or corrupted drivers can trigger the b1initializelibrary failed 0xc00000bb error. Updating or reinstalling drivers, especially graphics and chipset drivers, may help.

To update drivers:

  1. Press Windows + X and select Device Manager.
  2. Expand categories such as Display adapters or System devices.
  3. Right-click the device and select Update driver.
  4. Choose Search automatically for updated driver software.

If updating doesn’t work, try reinstalling:

  1. Right-click the device in Device Manager and select Uninstall device.
  2. Restart your PC; Windows will attempt to reinstall the driver automatically.

Step 5: Check for Software Conflicts

Sometimes third-party software can interfere with system libraries. To check for conflicts:

  1. Press Windows + R, type msconfig, and press Enter.
  2. Go to the Services tab.
  3. Check Hide all Microsoft services to avoid disabling essential system processes.
  4. Click Disable all to turn off non-Microsoft services.
  5. Go to the Startup tab and click Open Task Manager.
  6. Disable all startup items.
  7. Restart your computer.

If the error disappears, enable services and startup items one by one to identify the problematic software.

Step 6: Perform a Clean Boot

A clean boot starts Windows with minimal drivers and startup programs. This helps isolate software conflicts causing the error.

To perform a clean boot:

  1. Repeat the steps from Step 5 to disable all non-Microsoft services and startup items.
  2. Restart your computer.
  3. Check if the error still occurs.

If the error is gone, gradually re-enable services and startup programs, restarting each time until the error returns. This will help pinpoint the cause.

Step 7: Restore Windows to a Previous Point

If the error started recently, using System Restore can revert your system to a state before the error appeared.

To use System Restore:

  1. Press Windows + S and type create a restore point, then select it.
  2. Click the System Restore button.
  3. Follow the prompts to choose a restore point dated before the error began.
  4. Confirm and let Windows restore your system.

This will not affect your personal files but may uninstall recent apps or drivers.

When Nothing Works: Final Options

If none of the above steps solve the error, consider these last resorts:

  • Reset Windows 11: Go to Settings > System > Recovery and choose Reset this PC. You can keep your files or perform a full reset.
  • Contact Microsoft Support: Visit the official Microsoft support website for assistance tailored to your issue.
  • Seek Professional Help: If unsure, a qualified technician can diagnose and fix hardware or software problems.
