If you’re encountering the 0xc0000135 error on Windows 11 after attempting to install the KB5013943 update, you’re not alone. This error typically indicates missing or corrupted system files or issues with required components like the .NET Framework. Resolving this problem ensures your Windows 11 system remains up-to-date, secure, and running smoothly. Before starting, ensure you have a stable internet connection, administrator access to your computer, and enough free disk space to perform updates and repairs.

What You’ll Need

  • Administrator access to your Windows 11 PC
  • Stable internet connection
  • At least 10 GB of free disk space
  • Optional: a USB drive with Windows 11 installation media (if recovery is needed)

Step-by-Step

  1. Restart Your Computer: Begin by restarting your PC. Sometimes, a simple reboot can resolve temporary glitches causing the error.
  2. Run Windows Update Troubleshooter:
    • Go to Settings > System > Troubleshoot > Other troubleshooters.
    • Click on ‘Windows Update’ and then ‘Run the troubleshooter.’
    • Follow the on-screen instructions and apply recommended fixes.
  3. Check for Pending Updates:
    • Navigate to Settings > Windows Update.
    • Click ‘Check for updates’ and install any available updates.
  4. Repair or Reinstall .NET Framework: The 0xc0000135 error often relates to missing .NET components.
    • Download the latest .NET Framework installer from the official Microsoft website.
    • Run the installer and select ‘Repair’ if available, or uninstall and then reinstall.
    • Restart your computer after the process completes.
  5. Reset Windows Update Components:
    • Open Command Prompt as administrator (search ‘cmd’, right-click, select ‘Run as administrator’).
    • Stop Windows Update services: 
      net stop wuauserv
net stop cryptSvc
net stop bits
net stop msiserver
    • Rename SoftwareDistribution and Catroot2 folders: 
      ren C:\Windows\SoftwareDistribution SoftwareDistribution.old
ren C:\Windows\System32\catroot2 catroot2.old
    • Restart the services: 
      net start wuauserv
net start cryptSvc
net start bits
net start msiserver
    • Try running Windows Update again.
  6. Use Media Creation Tool or ISO for Manual Update: If automatic updates fail, manually update using the Media Creation Tool:
    • Download the tool from Microsoft’s official site.
    • Create installation media on a USB drive.
    • Boot from the USB and select ‘Upgrade this PC now.’
  7. Perform a System File Check and DISM Scan:
    • Open Command Prompt as administrator.
    • Type: 
      sfc /scannow

      and press Enter. Wait for the scan to complete.

    • Next, run DISM: 
      DISM /Online /Cleanup-Image /RestoreHealth

      . Wait for it to finish.

    • Reboot and check if the update installs successfully.

Common Mistakes

  • Skipping the administrator steps, which can prevent system repairs from executing properly.
  • Interrupting the repair process or shutting down during system scans.
  • Using unofficial or outdated installers for .NET Framework or Windows updates.
  • Ignoring error messages or logs that could provide clues to the root problem.
  • Attempting to manually install updates without ensuring system health beforehand.

Tips

  • Always back up important data before performing major repairs or updates.
  • Keep your system drivers updated to prevent compatibility issues.
  • Regularly run Windows Update Troubleshooter to catch problems early.
  • Ensure your system date and time are correct, as incorrect settings can interfere with updates.
  • Use the Microsoft Support and Community forums for additional help if the problem persists.

Troubleshooting

If the above steps do not resolve the 0xc0000135 error during the KB5013943 update, consider the following options:

      Go to Control Panel > System > System Protection > System Restore.
      Follow the prompts to select a restore point.
  • Use Windows Recovery Environment (WinRE):
    • Boot into WinRE by turning your PC off and on three times during startup.
    • Select ‘Troubleshoot’ > ‘Advanced options’ > ‘Startup Repair.’
