Just warn, don't bail

Even if the OS detection returns non-Win7, maybe it's Win 8 or something
where it'll still work. We rarely bail out on checks like these.

If I'm crazy, feel free to skip or revert this commit (it shouldn't hold
up the release at all)

For details on this module, see #2503. I don't see any comments about
this line in particular
