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.

    https://www.catalog.update.microsoft.com/Search.aspx?q=KB5050009

    Download from this link, install the x64 one. 1 will give you an error and another will work.
 Then just reboot and that's it. I just did it and it worked for me.

    I´ve got the same error.

    Unfortunately opening https://www.catalog.update.microsoft.com/Search.aspx?q=KB5050009 results in a timeout.

    Either searching the packet on catalog.update.microsoft.com.

    Maybe there are actually a lots of downloads because of this error?

    I get failed installation when I install the x64 option. I actually have 3 options...one is arm64 and the other two are 24H2 x64. One x64 is for Microsoft Server Operating System. The other x64 option is for Windows 11. My failed installation occurred on the x64 Windows 11 installation.

    Any other thoughts for how to get this update installed successfully?

    Did you try the 2 x64 based system files?
