Hello,

The example line might be:
.\Update-StartLayoutInWim.ps1 -Path C:\Install.wim -LayoutModification C:\LayoutModification.xml

Is there a way, to update all indexes in a wim-file? In my wim-files there's index 1 "Windows Home", index 2 "Windows Education" and index 3 "Windows Pro" ... and so on.

I would like to update all LayoutModifications in all wim indexes..

Thx
