When building win7pe se looks like regardless of other settings that the vista imageex is used for compressing the files to wim.
Build\0-preconfig.script
If,%ExtractWimFolder%,Equal,Yes,Begin

IniWrite,%projectdir%\script.project,IniVariables,WIMDriver,%WIMDriver%
On win8 x64 this version is 4 times slower doing the compression than the win 8 6.2.9200 version of imagex ( 4 minutes versus 30 seconds ). Can win7pe se be changed to support the use of win 8 adk files on win8?
