Why does Windows update 2023-09 Cumulative Update Preview for Windows 11 Version 22H2 for x64-based Systems (KB5030310) fail to install when it's not for my co-workers? All other updates are downloaded and installed with no problem. I believe this is the Pre-CoPilot update that I have been waiting for. Install error Install error - 0x80070002.

    Thanks for this David. I tried everything and nothing worked. I'm getting Install error - 0x80070002

    I'm doing this on a less than a week old computer. Can you please help?

    Thanks

    I´m having exactly the same problem for weeks now.

    I already tried the fix that was posted here.

    It seems to only be this one update. Other updates like Defender signatures and stuff go through.

    Error Code 0x800f081f means CBS_E_SOURCE_MISSING.

    Perform a repair installation known as In-place Upgrade to fix the problem.

    https://answers.microsoft.com/en-us/windows/forum/all/how-to-run-in-place-upgrade-in-windows-11/4d469147-2747-4dcb-88a4-aae9273a4500 

    Make sure you always back up your data when performing a repair installation.

    Because even an in-place upgrade can go wrong in the worst case scenario.

    You should also temporarily uninstall third-party antivirus programs beforehand and also use the removal tool if the manufacturer provides one.

    Greetings

    It´s always stuck during download. Do you have a workaround for this?
