I have been using Office 2007 for several years.
I have a new laptop being built and want to get a copy of 2007 as I know it and it fills all my needs.

However, I'm concerned that some which are offered on ebay that "are no longer used", etc. have been activated / registered and can't be used again even though the sellers assure that they have the product key.

My experience has been that once a MS product has been activated / registered it can't be used on another computer unless it is deactivated / de-registered.

What say the folks in the know?

Thanks
