If Vista is not activated with a legitimate product registration key in time, the system will run in 'reduced functionality mode' until it is activated, said Thomas Lindeman, a senior product manager at Microsoft. In this mode, people will be able to use a Web browser for up to an hour, after which time
the system will log them out, he said. On a related note, Microsoft later this month plans to roll out an Express Upgrade program that gives buyers of Windows XP-based PCs a
coupon for a free or discounted upgrade to Windows Vista through March 15.
