So KB5027397 is Microsoft-Windows-23H2Enablement-Package. So if lower iso version is wanted,. look out for Enablement-Package in updates, remove it before build, good to know, nice and easy Thanks.
Code: 1.Set AutoStart =0 and AddUpdates =0 in 22631.2506_amd64_en-us_professional_a8198661_convert\ConvertConfig.ini 2.Download packages, goto 22631.2506_amd64_en-us_professional_a8198661_convert\UUPs folder delete windows11.0-kb5027397-x64.cab 3.Set AddUpdates =1 in 22631.2506_amd64_en-us_professional_a8198661_convert\ConvertConfig.ini 4.Run 22631.2506_amd64_en-us_professional_a8198661_convert\convert-UUP.cmd
Code: Remove CU package for .NET Framework as well. Set AddUpdates =1 in 22631.2506_amd64_en-us_professional_a8198661_convert\ConvertConfig.ini Run 22631.2506_amd64_en-us_professional_a8198661_convert\convert-UUP.cmd
That's what I did. It includes the CU and the CU for .NET Framework. I only want to have the 22621.2506 build without the CU for .NET Framework.
