Microsoft records the MAC address (Medium Access Control – each network card has a unique ‘DNA’ code that can be used to uniquely identify individual computers operating under the same IP address – but it can be faked).Microsoft records the IP address of each activation, and a reasonable number of activations allowed from up to 3 different IP addresses (not unlimited, but more than 3).The copy can only be activated 3 times – period.how do they implement the 3 copies restriction? Off the top of my head I can think of only three ways:. The answer is YES – you can use one copy of Microsoft Office on up to 3 personal computers – although each copy requires ‘activation’ over the internet, which probably means that Microsoft records information about each computer to make sure that the package is only installed the three times. I Googled to try and find this out, and turned up no answer, so like every good ‘experimenter’ I just went ahead and tried it. This is a really valid concern, as I understand Microsoft’s other new release, Vista is quite strictly a ‘one computer only’ package. One concern I did have was whether or not I’d be able to use Office 2007 on the various computers I have (for instance my laptop as well as my main desktop). Can Microsoft Office 2007 be used on Multiple Computers? The package as a whole installs very easily, and I really like the new ‘Web 2.0’ style interface.

I have to say, they have done a very good job.
