I'm looking for a/the way to tell if a given WIM was captured from a machine that was sysprep'd with the (equivalent of the) /generalize parameter. Interested in Server 2003 R2 as the source platform (x86 and amd64 architectures).
Server 2008 seems to do something with the Registry:
HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Setup\State
Such that we can detect that at WIM mount. However, 2003 does not seem to have this or an equivalent that I can determine.
