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.

    Hi... I was having this very same problem for the past 24 hours. I tried everything sugested by the good people on here, but nothing seemed to work. After countless failed attempts to retry download and re-install, I tried to download the update manualy and use the standalone installer. This also failed.

    I then went into my bios to see if I might need to update it, I didn't need to as I have the latest bios for my motherboard, but I happened to notice that the PTT had been disabled by something and my TPM was not working. I enabled PTT, checked TPM was enabled and working before going back in to windows and hey presto the update downloaded and installed without a problem. So if you're having this issue it may help you to check the status of your TPM. I hope that this might help people while accepting there could be any number or reasons for this update failing to update your computers. Alan

    I had a similar issue. I needed to disable the 'Windows Sandbox' feature - restart my computer and then the update was installed successfully!

    Maybe this will help other people.

    That did not fix it for me unfortunately.

    I've finally fixed mine btw. What I did was reset the Windows to the previous version before the update, then I reinstalled the update again. Fixed my issue
