This probably is win 11, install it and check or check it by running: Code: dism /English /Get-WimInfo /WimFile:"C:\win10\sources\install.wim"
e.g. Windows 10 x64+x86 wim Right click on your W10x64 wim, choose export to wim, destination to your W10x86 wim. NTLite will ask 'Yes' to overwrite 'No' to append, choose No
That uses the exact same commands as when running the dism export commands manually. Gimagex can do exports too.
