Windows does absolutely no such thing.
Please, lets keep the support offered here grounded in reality. I don't want to have to start throwing my weight around and deleting posts filled with misinformation, I shouldn't have to.
*Windows* doesn't do anything differently here.
There is an issue with some Windows *applications* that make assumptions based on VID/PID, but Windows itself couldn't care less. As far as it is concerned, nothing changed at all. And even if the user had any one of the problematic applications installed on the system it wouldn't affect the host's ability to detect or mount the device at all.
A Macintosh, however...but, I digress. I'm somewhat sensitive when it comes to people making outright false claims, as a user like yourself has no way of knowing the claims made aren't actually true until someone like myself steps in and rectifies the situation.
What you're almost certainly going to have to do here is mount the iPod using the fallback image embedded in emCORE.
There is a known working revision of Rockbox embedded into emCORE itself to provide USB access in an event such as this one. You can access it via:
emCORE main menu(*) -> Tools -> Run Rockbox fallback image

(* this may require holding down any key during boot to expose the emCORE menu if you have set the emCORE fastboot mode)
