Windows Insider Update KB5062673 is not installing

Hey guys, hope this message finds you well. I've tried for a bunch of days to install Cumulative Update for Windows 11 Insider Preview (KB5062673) (26120.5733)
on my Windows 11 Pro. But I received an error (0x800f0831), and this update was not installed, nor was it hidden.


I've tried uupdump.net ISO file 26120.4452_amd64_pt-br_professional_356d2697_convert according to my Windows 11 Pro Version, but it doesn't work.


I received (0x800f0915) error when I tried to mount the ISO in letter E, and run the following command: `DISM /Online /Cleanup-Image /RestoreHealth /Source:E:\Sources\install.wim /LimitAccess`


I used my laptop for work, which means I can't format and install everything from 0.


Can you provide me with any tips to solve this issue?


Thanks for your time in advance.

    Nguyenais​ I solved my problem with Windows In-Place Upgrade Repair. Basically it means you'll need to download a ISO from Windows 11, mount this ISO and click in setup.exe and follow a simple steps.

    Now the same issue, but with (KB5064093) (26120.5761). Looks like the numbers are changing, but the issue persists

    It sounds like you're facing persistent update errors (0x800f0831 and 0x800f0915) when trying to install KB5062673 on your Windows 11 Pro Insider build, and you're concerned about avoiding a full reinstall due to work dependencies.
