So, just for clarification: - There's only an Enterprise ISO available from MSDN that includes the GA update - The Enterprise ISO can't be used for Core/Pro installs? - The only Core/Pro ISO available is pre-GA (WZT) - The GA update will appear on Windows Update as-expected if one uses a pre-GA ISO?
That seems to be it. Hard to tell what the differences are between the download setupbox 8.1 iso and the rtm with rollups. Need to get an en-US 8.1 setupbox download to compare properly.
