"It is also worth noting that Registry changes are necessary because every new Windows Update will attempt to install Outlook (new).

For example, if you install #KB5051974 today, then manually uninstall the new Outlook in the hope that it will not show up again. This will not work."

Seem to be getting a #WindowsUpdate failure every night for #KB5051974 on #Windows10 with error code #0x800f0922

Found this but I don't know how relevant it is to me because it seems to be about Windows Server instead: https://learn.microsoft.com/en-gb/troubleshoot/windows-server/installing-updates-features-roles/error-0x800f0922-installing-windows-updates

The steps to remove the packages worked, but not the registry key deletions.

Looks like this is the problem update: https://support.microsoft.com/en-gb/topic/february-11-2025-kb5051974-os-builds-19044-5487-and-19045-5487-687841b4-97c9-493a-8cb8-ba3b8c077c7e

Error code 0x800f0922 when installing Windows updates - Windows Server

Helps resolve the 0x800f0922 (CBS_E_INSTALLERS_FAILED) error when installing Windows updates.
