Any VISTA distribution is... simply not going to work! Where have you been? Microsoft has completely locked their system, so that in order to activate the OS, one needs to contact (through the internet, of course) the Microsoft activation server.
Of course, any commercial outfit bundling h/w and s/w has no problem, and for anyone actually buying the s/w intending to install on x h/w, you MUST have an internet connection to activate it.
Now, maybe there's some cleaver folks out there to get around this, but basically they'd have to also disable all the 'talk-back' (through the internet again, of course) parts of the OS to prevent any 'dead codes' being sent to your pirated copy. Again, you could simply never connect it up (to the internet), but....
It's a pretty tight system.
