If I buy the Vista 'builders' version, I can only install that on one
machine, ever?
If by "builder's version" you mean an OEM copy of windows: yes, it can only
be activated on one machine. That's why it's so much cheaper than a retail
copy. It can also normally only be purchased if you buy a new computer (or
at least the motherboard) at the same time.
Licensing is usually tied to the motherboard so you can still upgrade other
components. I think XP used to allow hree major hardware changes before
forcing you to reactivate; I don't know if Vista's the same.
If that machine dies and I build another, I can't use that version of
Vista Premium?
If the machine dies and you have to replace the motherboard, as long as it's
the same as (or if you can't get one the same, equivalent in performance to)
the old one you can call Microsoft and explain you've had to replace it due
to a fault and they'll issue you with a new product key. Of course, with
really old machines, any replacement motherboard would almost certainly be
an upgrade so then you'd have to budget for a new OEM copy of Windows.
But seeing as how the versions of Vista change practically monthly.
The overall version of Windows only changes every few years. Vista is
version 6; version 7 is currently in Beta test stage. An OEM copy of Windows
is identical to the retail version, so all Service packs and Windows Updates
can still be installed in the same way.
What's the best approach?
If you're looking to build a machine to last you for the next couple of
years, get an OEM copy as part of your components list. If you like to chop
and change stuff, and upgrade every few months, a retail copy might be a
better idea.
