For customers who acquired a full or upgrade version of Windows Vista from retail or pre-installed, we've got a pretty sweet deal. We're announcing the Windows Vista Additional License program, which provides the ability to install the same edition of Windows Vista on any other additional computers you may own. The program allows customers to purchase up to 5 additional licenses for PCs they own at 10% off the suggested retail price.
Windows Vista requires 1 license per device. When attempting to install and activate the same licensed copy of Windows Vista on another PC, activation won't work. When the activation fails, the user is directed to purchase additional licenses online or by phone. Remember, not properly activating Windows Vista will lead to it running in reduced functionality mode, so this new program is a handy way to avoid that situation. With it, customers can use their original Windows Vista media for installation and activate each installation using the newly purchased licenses. This means there's no need to wait for new media to arrive in the mail -- although that option is available in case the original media is lost or otherwise unavailable.
For North America, Windows Vista Additional License online orders opened 19 March (yesterday) and phone orders were available as of 28 February. For our EMEA friends, online orders will be available on 26 March, with phone orders currently planned for a future date.

The program is designed to run through the entire product lifecycle of Windows Vista; thus, no end date has yet been established.
Note that other types of licenses such as Volume Licensing, MSDN, TechNet and evaluation copies do not qualify for the Additional License Program.
