How to Fix Windows Update Client Failed to Detect Error 0x8024a005 on Windows 11

If you are encountering the error code 0x8024a005 while trying to update Windows 11, it means the Windows Update client is having trouble detecting updates. This can be frustrating but is usually fixable with some straightforward steps.

Windows Update is an essential part of keeping your PC secure and running smoothly. When it fails, it’s important to address the issue promptly to avoid missing important updates.

This guide will walk you through simple, step-by-step solutions to resolve the error and get Windows Update working again.

Each step is explained clearly so even beginners can follow along without confusion.

Quick Note Before You Begin

  • Make sure your PC is connected to the internet. Updates require a stable connection.
  • Check if your Windows 11 version is supported. Older versions might have issues receiving updates.
  • Ensure you have enough free disk space on your system drive (usually C:). Updates often need extra space to install.
  • Temporarily disable any third-party antivirus or firewall software that might block update services.

Step 1: Run the Windows Update Troubleshooter

The Windows Update Troubleshooter is a built-in tool designed to automatically detect and fix common update problems.

  1. Click the Start button and select Settings.
  2. Go to System and then Troubleshoot.
  3. Select Other troubleshooters.
  4. Find Windows Update and click Run.
  5. Follow the on-screen instructions. The troubleshooter will look for issues and try to fix them.

Running this tool first is important because it automatically addresses many common problems without needing technical expertise.

Step 2: Restart Windows Update Services

Windows Update relies on specific services running in the background. Sometimes these services can get stuck or encounter errors, causing update detection to fail.

  1. Press Win + R to open the Run dialog.
  2. Type services.msc and press Enter to open the Services window.
  3. Scroll down and find the following services:
    • Windows Update
    • Background Intelligent Transfer Service (BITS)
    • Cryptographic Services
  4. For each service, right-click it and select Restart.
  5. If the service is not running, right-click and select Start.

Restarting these services refreshes their operation and often resolves detection errors.

Step 3: Clear the SoftwareDistribution Folder

The SoftwareDistribution folder stores temporary files related to Windows Update. Sometimes corrupted files here can cause update errors.

Clearing this folder forces Windows to download fresh update files.

  1. Open the Command Prompt as an administrator:
    • Press Win, type cmd, then right-click Command Prompt and select Run as administrator.
  2. Stop Windows Update services by typing the following commands one by one, pressing Enter after each: 
    net stop wuauserv
net stop bits
net stop cryptsvc
  3. Next, delete the contents of the SoftwareDistribution folder. Type: 
    del /f /s /q %windir%SoftwareDistribution*

    This command deletes all files inside the folder but not the folder itself.

  4. Restart the services by typing: 
    net start wuauserv
net start bits
net start cryptsvc
  5. Close the Command Prompt and try checking for updates again.

This step is crucial because corrupted or incomplete update files often cause detection failures.

Step 4: Reset Windows Update Components Using a Script

If manually restarting services and clearing files didn’t help, you can use a script to reset all Windows Update components fully.

This process resets the update database and related settings, fixing deeper problems.

  1. Open Notepad and paste the following code exactly:
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
pause
  1. Save the file as ResetWU.bat on your Desktop.
  2. Right-click the file and select Run as administrator.
  3. Wait for the script to finish and the Command Prompt window to pause.
  4. Press any key to close the window.
  5. Restart your computer and try updating Windows again.

This method is more advanced but very effective when simpler fixes don’t work.

Step 5: Use the System File Checker (SFC) Tool

Corrupted system files can interfere with Windows Update. The SFC tool scans and repairs these files.

  1. Open Command Prompt as administrator (see Step 3).
  2. Type the following command and press Enter: 
    sfc /scannow
  3. Wait for the scan to complete. It may take several minutes.
  4. If any issues are found, the tool will attempt to fix them automatically.
  5. Restart your PC after the process finishes.

Running SFC ensures your system files are healthy, which is necessary for Windows Update to function correctly.

Alternative Method: Manually Download and Install Updates

If Windows Update still fails, you can manually download updates from the Microsoft Update Catalog.

  1. Go to Microsoft Update Catalog.
  2. Search for the KB number of the update you want to install (you can find this in the Windows Update settings under update history).
  3. Download the correct update package for your system (x64 or ARM64).
  4. Run the downloaded file and follow the installation prompts.

This method bypasses the Windows Update client and can be a helpful workaround.
