Windows Vista will have new antipiracy technology that locks people out their PCs if the operating system isn't activated within 30 days after installation.
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.
