If you are encountering the Windows Update Error 0x800f0805, you are not alone. This error can hinder your system from receiving important updates, which may affect your PC’s performance and security. In this guide, we will walk you through several effective methods to troubleshoot and resolve this issue on Windows 10 and Windows 11 systems, ensuring that you can successfully install updates and maintain your system’s health.

Before you start, ensure you have administrative access to your computer, as some steps require elevated permissions. No prior downloads are necessary, but make sure your operating system is updated to the latest version available.

Step 1: Use the Windows Troubleshooter

The built-in Windows troubleshooter can automatically detect and fix problems with Windows Update. Follow these steps:

  1. Click on the Start menu and type Troubleshoot settings in the search bar.
  2. Select the Troubleshoot option from the search results.
  3. Click on Other troubleshooters.
  4. Locate the Windows Update troubleshooter and click Run next to it.

Wait for the troubleshooter to detect any issues. If problems are found, it will attempt to resolve them automatically. After the process is complete, check if the error persists.

Step 2: Run System File Checker (SFC)

If the troubleshooter does not resolve the issue, the next step is to use the System File Checker tool. This tool scans for and repairs corrupted system files that might be causing the error.

  1. Open the Start menu, type cmd, and right-click on Command Prompt. Select Run as administrator.
  2. Click Yes when prompted by User Account Control.
  3. In the Command Prompt, type the following command and press Enter: sfc /scannow

Wait for the scan to complete. This may take some time. Once finished, restart your computer and check if the issue is resolved.

Step 3: Use the Deployment Imaging Service and Management Tool (DISM)

If the error persists, using the DISM tool can help restore the health of your Windows image. Follow these instructions:

  1. Again, open the Command Prompt as an administrator.
  2. Type the following command and press Enter: dism /online /cleanup-image /restorehealth

This process may take a while as well. Once it’s complete, restart your computer and check for updates again.

Step 4: Reset Windows Update Components

If none of the previous steps worked, you may need to manually reset the Windows Update components. This can be done via the Command Prompt:

  1. Open the Command Prompt as an administrator.
  2. Type the following commands one at a time, pressing Enter after each:
  • net stop wuauserv
  • net stop cryptSvc
  • net stop bits
  • net stop msiserver
  • net stop trustedinstaller
  • Now, rename the SoftwareDistribution and Catroot2 folders:
    • ren C:\Windows\SoftwareDistribution SoftwareDistribution.old
    • ren C:\Windows\System32\catroot2 Catroot2.old
  • Finally, restart the services you stopped earlier:
    • net start wuauserv
    • net start cryptSvc
    • net start bits
    • net start msiserver
    • net start trustedinstaller

    After completing these steps, restart your computer and attempt to update Windows again.

    Here are some additional tips to keep in mind:

    • Ensure your internet connection is stable while downloading updates.
    • Temporarily disable any antivirus software, as it might interfere with the update process.
