What if I want to bring along specific DLLs?

If there were a special DLL you wanted to bring along, you’d put it in the VAA and the app would look for it first in the VAA.  The intercept layer looks first in the VAA for a file that is requested.  If for some reason, you choose to bring a part of the OS along – an OS DLL – we’ll see it there as well.  It can be picked up by the creator process or simply added into the file structure later.
