Error Code 0x80240055 Summary

The error code 0x80240055 typically indicates an issue encountered during Windows Update operations, specifically relating to failure in downloading or installing updates on a Windows system. This error can occur when trying to install critical updates, feature updates (like Windows 10/11 upgrades), or cumulative updates through the Windows Update service.

Description of Error 0x80240055 and Where It Can Occur in Windows Update Process

This error can occur in several contexts within the Windows operating system environment: during routine installation of updates through the built-in Windows Update feature; when attempting to manually download and install specific Windows updates from Microsoft’s servers via the Settings app or Control Panel; and also while running the “Windows Update troubleshooter” tool designed to automatically fix common update issues. Additionally, it may appear when using Group Policy settings or system management tools that are configured to manage software updates for enterprise environments.

Howto solve error code 0x80240055

  1. To resolve the error 0x80240055, start by ensuring your Windows version is up-to-date and there are no pending critical updates. Go to Settings > Update & Security > Check for Updates.
  2. If updates exist, install them one at a time starting from the oldest to isolate if any specific update causes the issue.
  3. Run the built-in Windows Update troubleshooter by going to Settings > Update & Security > Troubleshoot and selecting “Windows Update.”
  4. Check for corrupt or missing files in your system using SFC (System File Checker) and DISM (Deployment Imaging Service and Management Tool). Open Command Prompt as Administrator and run:
    sfc /scannow

    Then, execute:

    dism.exe /online /cleanup-image /scanhealth
  5. Verify your internet connection stability. Try restarting your router or switching to a different network if possible.
  6. Clear temporary files that could be interfering with updates by going to Settings > System > Storage > More storage settings > Temporary files and clean them up.
  7. If issues persist, consider performing an in-place upgrade of Windows (keeping all personal data and apps) via Media Creation Tool or through the Upgrade option available in Windows Update. This process essentially resets update installation problems without reinstalling from scratch.
