If you are upgrading your computers from XP or Vista to Windows 7, look for
the Family Pack. It has three licenses (i.e. for three computers) and
steeply discounts the upgrade price:

For example in Canada.:

Windows 7 can be obtained at around 65 bucks a copy Canadian.

Whereas in the United States for example:

You can get Windows for around 49 bucks a copy. Less than $50 USD for a copy
of Windows 7.

So if you have more than one computer you want to upgrade, look into the
Family Pack. You *can* use the upgrade media to do a clean install and still
get Windows to Activate and pass Genuine Advantage. Just check Paul
Thurrott's website for the simple instructions:
