Hi All,
I have a Windows Server 2022 device that is now encountering issues with Windows Update, specifically the current KB5051979 (returning error 0x800f0831).

I also have attempted to do an in-place re-install from a new Server 2022 ISO but it fails at the reboot phase, referencing 0x8007000d - 0x20006 kb5051979
I have tried all manner of DISM and SFC scans, including using the fresh ISO as the source. But no luck at all.
Thanks in advance!
