How to Fix Windows Update Error 8024402F on Windows 8.1: Complete Troubleshooting Steps

Windows Update Error 8024402F can be frustrating when you are trying to keep your Windows 8.1 system up to date. This error usually occurs due to connection problems between your computer and the update servers.

Fixing this error is important because Windows updates include critical security patches and performance improvements. Without these updates, your system might be vulnerable to threats or run less efficiently.

In this guide, you will find simple, step-by-step instructions to resolve this error and get your updates working again. Even if you are not very technical, the explanations will help you understand what each step does.

Follow the steps carefully, starting from the easiest solutions and moving to more advanced options if needed.

Quick Note: Before You Begin

  • Make sure your internet connection is stable and working.
  • Temporarily disable any third-party antivirus or firewall software, as these can sometimes block updates.
  • Confirm that your system date and time are set correctly, as incorrect settings can cause update errors.
  • Have your Windows 8.1 product key handy, just in case you need it later.

Step 1: Run the Windows Update Troubleshooter

The Windows Update Troubleshooter is a built-in tool designed to detect and fix common update problems automatically. This is the simplest and safest first step.

  1. Press Windows key + W to open the search charm.
  2. Type troubleshooting and select the Troubleshooting option.
  3. Click on Fix problems with Windows Update under the System and Security section.
  4. Follow the on-screen instructions to let the troubleshooter scan and repair issues.

Running this tool can save time by addressing common errors without manual intervention.

Step 2: Check Your Internet Connection and Proxy Settings

Sometimes, Windows Update cannot connect properly because of incorrect internet or proxy settings.

  1. Open Control Panel and go to Internet Options.
  2. Switch to the Connections tab and click LAN settings.
  3. Make sure the box next to Automatically detect settings is checked.
  4. Ensure that the box for Use a proxy server for your LAN is unchecked, unless you specifically use a proxy.
  5. Click OK to save changes and close the windows.

Incorrect proxy settings can block your computer from reaching Windows Update servers, causing error 8024402F.

Step 3: Clear the Windows Update Cache

Corrupted or incomplete update files in the cache can cause update failures. Clearing the cache forces Windows to download fresh update files.

  1. Press Windows key + X and select Command Prompt (Admin).
  2. Type the following commands one by one, pressing Enter after each:
net stop wuauserv
net stop bits

This stops the Windows Update service and Background Intelligent Transfer Service (BITS).

  1. Navigate to the update cache folder by typing:
    del %windir%SoftwareDistributionDataStore*.* /s /q
    This deletes cached update data.
  2. Start the services again by typing:
net start wuauserv
net start bits

After this, try running Windows Update again. This method clears any corrupted update files that might be causing the error.

Step 4: Reset Network Components

Network components like TCP/IP or Winsock can sometimes cause connectivity issues affecting Windows Update. Resetting these components can solve such problems.

  1. Open Command Prompt (Admin) again.
  2. Type the following commands one at a time, pressing Enter after each:
netsh winsock reset
netsh int ip reset
ipconfig /release
ipconfig /renew
ipconfig /flushdns

These commands reset the network stack and refresh your IP settings, helping to fix communication issues with update servers.

Step 5: Temporarily Disable Firewall and Antivirus Software

Firewalls and antivirus programs can sometimes block Windows Update from working properly.

  1. Locate your antivirus or firewall icon in the system tray (bottom-right corner).
  2. Right-click and look for an option to disable or turn off protection temporarily.
  3. Confirm any prompts that appear.
  4. Try running Windows Update again.

If disabling these programs fixes the issue, consider adding Windows Update as an exception in your antivirus or firewall settings. Remember to turn your protection back on afterward.

Step 6: Use the System File Checker (SFC) Tool

System files related to Windows Update might be corrupted. The System File Checker tool scans and repairs these files automatically.

  1. Open Command Prompt (Admin).
  2. Type sfc /scannow and press Enter.
  3. Wait patiently as the tool scans and repairs files. This can take several minutes.
  4. Once done, restart your computer and try updating again.

Running SFC helps ensure your system files are intact and not causing update errors.

Step 7: Advanced Option – Manually Download Updates

If none of the above works, you can manually download and install updates.

  • Note the specific update code from the Windows Update history (e.g., KB1234567).
  • Go to the Microsoft Update Catalog.
  • Enter the update code in the search box and download the update file that matches your system.
  • Run the downloaded file to install the update manually.

This bypasses the automatic update system, which can help if the error is persistent.
