In this article, we will guide you through simple, step-by-step solutions to resolve the error on Windows 11. Each method is explained clearly, so even beginners can follow along. Let’s get started and get your updates working again.

Fixing this error usually involves checking your internet connection, resetting update components, or repairing system files. By following the steps below, you can quickly identify and fix the problem.

Remember, keeping your Windows 11 system updated is essential for security and performance. So, let’s ensure your updates run smoothly.

Quick Note: Before You Begin

  • Make sure your internet connection is stable and working properly.
  • Check that your system date and time are set correctly, as incorrect settings can cause update errors.
  • Temporarily disable any third-party antivirus or firewall software, as these can block updates.
  • Ensure you have enough free disk space on your main drive (usually C:) for the update to install.

Step 1: Run the Windows Update Troubleshooter

Windows 11 has a built-in troubleshooter designed to detect and fix common update problems automatically. This tool is easy to use and often resolves errors like 0x80240438 quickly.

  1. Click on the Start menu and open Settings.
  2. Go to System > Troubleshoot > Other troubleshooters.
  3. Find Windows Update in the list and click Run.
  4. Wait while the troubleshooter scans your system for problems.
  5. If it finds any issues, follow the on-screen instructions to fix them.
  6. Once finished, restart your computer and try updating again.

Why this helps: The troubleshooter automatically detects missing files, corrupted settings, or misconfigurations that can cause update errors.

Step 2: Check Windows Update Services

Windows Update relies on specific services running in the background. If these services are stopped or not working properly, updates can fail.

  1. Press Windows + R to open the Run dialog box.
  2. Type services.msc and press Enter.
  3. In the Services window, locate the following services:
    • Windows Update
    • Background Intelligent Transfer Service (BITS)
    • Cryptographic Services
  4. For each service, right-click and select Properties.
  5. Set the Startup type to Automatic.
  6. If the service is not running, click Start.
  7. Click Apply and then OK.
  8. After adjusting all three, restart your PC and try updating again.

Why this helps: These services manage the download and installation of updates. Ensuring they run correctly allows updates to proceed without interruption.

Step 3: Reset Windows Update Components Manually

If the previous steps did not fix the issue, resetting Windows Update components can clear corrupted files or settings causing the error.

Follow these instructions carefully:

  1. Open Command Prompt as an administrator:
    • Click the Start button, type cmd, right-click Command Prompt, and select Run as administrator.
  2. Type the following commands one by one, pressing Enter after each:
net stop wuauserv
net stop cryptSvc
net stop bits
net stop msiserver
ren C:WindowsSoftwareDistribution SoftwareDistribution.old
ren C:WindowsSystem32catroot2 catroot2.old
net start wuauserv
net start cryptSvc
net start bits
net start msiserver

These commands stop update services, rename folders storing update data (forcing Windows to create fresh folders), and restart the services.

After completing these steps, restart your PC and check for updates again.

Step 4: Scan and Repair System Files

Corrupted system files can trigger update errors. Using the System File Checker (SFC) and Deployment Image Servicing and Management (DISM) tools can repair these files.

  1. Open Command Prompt as an administrator.
  2. Run the System File Checker by typing:
    3. sfc /scannow
  3. Wait for the scan to complete; it may take several minutes.
  4. If SFC finds and repairs files, restart your PC.
  5. If problems persist, run the following DISM commands one at a time:
    6. Dism /Online /Cleanup-Image /CheckHealth
Dism /Online /Cleanup-Image /ScanHealth
Dism /Online /Cleanup-Image /RestoreHealth
  6. After DISM finishes, restart your computer and try updating again.

Why this helps: These tools check for and fix system corruption that can interfere with Windows Update.

Step 5: Temporarily Disable Proxy Settings

Sometimes, incorrect proxy settings can block Windows Update from connecting to Microsoft servers.

  1. Open Settings and go to Network & Internet.
  2. Select Proxy on the left menu.
  3. Turn off Automatically detect settings and Use a proxy server if enabled.
  4. Restart your PC and try updating again.

If disabling the proxy fixes the problem, you may need to adjust proxy settings or contact your network administrator for help.

Alternative Method: Use the Windows Update Assistant

If none of the above solutions work, you can try using the Windows Update Assistant tool. This official Microsoft utility forces your system to update to the latest version.

  • Visit the official Windows 11 download page.
  • Click on Download Now under Windows 11 Installation Assistant.
  • Run the downloaded tool and follow the prompts to update your PC.

This method bypasses some update issues and installs the latest Windows version directly.
