As we've seen, the Windows' ISOs volume IDs are rather bizarre. I think
that using a very generic regex runs a risk of matching bad ISOs. So my
idea is that we should only use precise volume ID matches. To counterbalance
this, my intention is to download all possible ISOs from MSDN, so we can
discover the full set of valid volume IDs & expand the strict matches.

Regards,
Daniel
