Emacs doesn't access these directly. Perhaps Windows does, in the
bowels of some API that Emacs calls.

This is accessed as part of initialization (because environment
variable might be set in the Registry), and also each time Emacs needs
to access GUI resources (because Emacs on Windows allows to store "X
resources" in the Registry).
Anyway, why do you think this is a bug?
