I have tried to update to 2025-01 Cumulative Update for Windows 11 Version 24H2 for x64-based Systems (KB5050009) but i get the (Install error - 0x80070306)

I have restarted and shut down my computer multiple times to see if that would fix it but it didn't. I've also tried re-installing the update as well.

Please let me know what i can do to.

    To avoid the error 0x800f0838, first, install this package: https://catalog.sf.dl.delivery.mp.microsoft.com/filestreamingservice/files/d8b7f92b-bd35-4b4c-96e5-46ce984b31e0/public/windows11.0-kb5043080-x64_953449672073f8fb99badb4cc6d5d7849b9c83e8.msu

    Hello,

    I tried to install the patch you recommend in order to avoid the error 0x800f0838 when installing the update KB 5050009 x64, however I end up with the following message “The update is not applicable to your computer. For more information, activate the documentation for this update to find out if you need to install another update first.”

    For your information, the last cumulative update KB installed on my computer is 5048667 on December 18th 2024. And the latest patch concerns .NET Framework 3.5 and 4.8.1 for Windows 11 24H2 (KB5049622), installed on January 15th, 2025.

    Computer used: Dell XPS 13 9315, Windows 11 Professional 24H2 build 26100.2894

    I am getting an error with the update as well. The system keeps stating "Pending restart", I restart and am faced with the same dilemma. I tried running the standalone installer from the following link: https://www.catalog.update.microsoft.com/Search.aspx?q=KB5050009 and get an error from the Standalone installer: "Installer encountered an error: 0x800f0838.

    To avoid the error 0x800f0838, first, install this package: https://catalog.sf.dl.delivery.mp.microsoft.com/filestreamingservice/files/d8b7f92b-bd35-4b4c-96e5-46ce984b31e0/public/windows11.0-kb5043080-x64_953449672073f8fb99badb4cc6d5d7849b9c83e8.msu

    Then, install this: https://catalog.sf.dl.delivery.mp.microsoft.com/filestreamingservice/files/66557ecc-650e-4c70-8baf-c624c4de912f/public/windows11.0-kb5050009-x64_97aac2ab4f607b11d50ad2fd88a5841ee0b18dd5.msu
