You are right, and I also am more interested in using the "correct" (i.e. current set of tools) to access Win7 WIM files. BUT, I'm not patient so I just extract the contents and point at that...One time cost and just diskspace...Thanks for the explanation, Scott.
My example was intended to demonstrate that the old wimfltr service is not desirable when trying to use dism or the Win7 imagex. I end up with directory full of faulty reparse points! For that reason, I am less interested in using the Vista imagex on Win7. Maybe I've become more patient.
From what I have heard, when using the Vista imagex on Win7 host OS, wimfltr and wimmount services running together seem OK provided that the WIM image is not Win7 SP1.
Some Win7PE_SE projects seem to install and start the old wimfltr by default, regardless of the OS, requiring a reboot to get rid of it. (Unlike wimmount which can be started and stopped with "net start ...")
As for the fact that if you don't set the recent Win7PE_SE project to always use the slower, current win7 version of the tools, it will try to use the older versions...Maybe this is something ChrisR can look at when he gets back from Vacation - i.e. unregister / uninstall the older wimfiltr...
