I cited the Microsoft web site sources in my message to Tiberius. I
have no way of finding and giving a link to this at present (and I may
have put the Subject on my Kill list since the thread was full of
stupidities and rudeness (surprised?)
But I tracked down exactly the words I quoted on the Microsoft website
but it took some digging beyond simple searching.
However here is part of the source:
Activating Windows Vista

------------------------------------------------------------------
X How many times can I install Windows on my computer before I have to
activate Windows again?
You can reinstall Windows on the same computer as many times as you
want because activation pairs the Windows product key with information
about your computer's hardware. If you make a significant hardware
change, you might have to activate Windows again.
X What hardware changes may require re-activation?
The Windows Vista re-activation process may vary based on how you
acquired Windows Vista. For example:
If you acquired Windows Vista via retail purchase (boxed product) or
pre-installed on a computer from a local computer vendor, Windows Vista
will require re-activation if you, for example:
Replace the hard disk drive and memory at the same time.
Replace the motherboard.
If you acquired Windows Vista pre-installed on a computer from a
major manufacturer (sometimes referred to as an Original Equipment
Manufacturer or OEM), Windows Vista will require re-activation if you
replace the motherboard with a motherboard not provided by the OEM.
If you acquired Windows Vista via a volume license upgrade visit the
Windows Vista Volume Activation page.
X What hardware changes can be made without re-activating?
Hardware changes that do not invoke the Windows Vista re-activation
process may vary based on how you acquired Windows Vista. For example:
If you acquired Windows Vista via retail purchase (boxed product) or
pre-installed on a computer from a local computer vendor, Windows Vista
will not require re-activation if you, for example:
Replace the hard disk drive only.
Replace the video card and add system memory at the same time.
If you acquired Windows Vista pre-installed on a computer from a
major manufacturer (sometimes referred to as an Original Equipment
Manufacturer or OEM), Windows Vista will require re-activation if you
replace the motherboard with a motherboard not provided by the OEM.
If you acquired Windows Vista via a volume license upgrade visit the
Windows Vista Volume Activation page.

If I were not using Text Only I would be able to highlight better but
the Questions I've marked with an X and the two replies about pre-
installed and changing motherboard I've indented the first line.
Note that it says "re-activation" and NOT a new licence.
