Cumulative Update for Windows 11 (10.0.22000.100) (KB5004300): Install error - 0x800f0989

    Miaomiaoywww + anyone else that stumbles on this thread - I managed to solve this.

     

    It was really tricky but I noticed in the cbs.log file that the majority of packages failing were ja-JP and en-GB language packs.

     

    To solve it, I switched my OS to US English and removed the additional language packs using DISM. After doing so, I was able to get a clean sfc /scannow + a clean DISM healthcheck.

     

    After that, I restarted my machine and retried the upgrade, which was installed successfully.

     

    After upgrading to the latest Windows build, I just reinstalled the language packs and removed US English again 😅

     

    It seems the way language packs are bundled has indeed changed with Windows 11, so I'm guessing there are some teething issues.

     

    Hope that helps!
