    Hi Alan Smith,

    Welcome to the Microsoft Q&A!

    I'm sorry to hear you're encountering the error with the Windows Update installation. The error code 0x800705b4 typically indicates a timeout error or that the service is not responding. This issue may be related to network issues, corrupted update components or conflicting third-party software. This is usually fixable by rechecking Internet, resetting update components or clearing cache.

    But if none of that doesn't work, you can try out some other options below:

    1 - Run Windows Update Troubleshooter & built-in repair

    • Open Settings > Systems > Troubleshoot > Other troubleshooters
    • Click Run next to Windows Update > Follow the prompts
    • If the issue persists, try Fix problems using Windows Update by going to Settings > System > Recovery > Reinstall now

    2 - Force-sync Insider updates with Command Prompt (Admin)

    The error sometimes occurs when the update line gets stuck. You can try running the following prompt: usoclient StartInteractiveScan to see if it works.

    3 - Reset the Insider Channel

    • Go to Settings > Windows Update > Windows Insider Program.
    • Click Stop getting preview builds > Restart.
    • Re-enroll > Check for updates again.

    4 - Clean the hidden components of Insider builds using PowerShell (Admin)

    Stop-Service -Name "Windows Update" -Force
    Remove-Item -Path "$env:windir\SoftwareDistribution\*" -Recurse -Force
    Remove-Item -Path "$env:windir\System32\catroot2\*" -Recurse -Force
    Start-Service -Name "Windows Update"
    

    5 - Manually install the pending Insider update or trying In-place upgrade:

    • Find your current build number by pressing Win + R > winver
    • Getting the Windows 11 Installation Assistant
    • Download the next Insider build from UUP Dump

    If the issue persists, your Insider Preview build might be corrupted! Consider a repair install with in-place upgrade > Download Windows Insider Preview ISO

    Let me know if you'd like help with the In-place upgrade or if the issue persists after trying these steps. Please understand that the first answer doesn't always solve the problem. In addition, this is an Insider program, so there's a chance this is a regression from the build itself and reporting it might help escalate the issue. Consider submitting feedback via the Feedback Hub (Win + F) to help Microsoft investigate further.
