Thanks for the useful link.
But ... it says there: "This policy will not work for the Windows 11 Home edition."
Is this true?π€
Yes, looks like the registry edit is unsupported in Home Edition. Deliberately triggering a gated block (e.g., having <20 GB of free space on the OS partition or creating a wallpaper registry key to inform the appraiser that a 3rd party wallpaper customization app is installed) should prevent the 24H2 upgrade from being installed automatically via Windows Update. It's a hackish way to stop the 24H2 feature update, but it works.
If you're facing issues with the 24H2 setup, please feel free to start a new thread and post the logs there. We'll be glad to assist you.
