DISM Says My Win7PE SE Is Vista

I made a new build today and I mounted the PE boot.wim as I always do to inject drivers with DISM and it unmounts my wim saying it can not service Vista. Not sure why it would be Vista. Using a Win 7 Ultimate source as always? 

Making a new build now and I unchecked the trim down PE option, the only thing I done different from the last few builds. 

Yup, guess you can't use the trim PE function without converting the Win7PE SE TO WinVistaPE SE! 

Interesting, and funny indeed 

can you test only selecting Trim option "Reduce - Rewrite Hive files"


I guess , dism not finding dism file(s) on target, make dism think it is vista as default,
baddd dism programmer badd, why dism not check more solid files like ntdll etc

Will test today.
