Windows update for Windows 11 version 24H2 fails to install

Hi, I'm John! I will help you with this.

Can I ask if you’ve already checked whether you have any third-party antivirus software running?

If you haven't tried anything yet please start by:

First, make sure there's no third-party antivirus software active that might be interfering with the update process:

• Open the Windows Security app.
• Click the "Settings" (gear icon) in the lower left.
• Under Security Providers, click "Manage Providers".
• Verify if Microsoft Defender Antivirus is the active antivirus and Windows Firewall is the firewall.
• If not, please uninstall the third-party antivirus, restart your PC, and check again at Settings > Windows Update.

Then run again the Windows Update Troubleshooter from Get Help app:

• Open Settings > System > Troubleshoot > Other troubleshooters.
• Find Windows Update and click Run. This will open the Get Help app.
• Select "I can't download, install, or uninstall an update" and click "Yes".
• This will automatically identify and address any errors and restart the update process. This step is purely automatic.
• Please continue to follow the prompt if the issue persists.

If the issue persists, please provide more details by answering my questions.
