Microsoft is taking action to thwart a possible hole in its Vista anti-piracy measures.

Users of the new operating system have to register their software in order to activate it. If that doesn't happen within a set time the software will lock-down giving limited functions until it is officially registered. But pirates have reportedly used bits of previous beta releases to create a version of the software which doesn't need to be activated. Another workaround uses the method Microsoft uses for activating software for enterprise clients.

Failing the test means your machine loses some functions, after thirty days if you do not produce a correct key you will only be able to use your default web browser for an hour. But you can still access you files by booting in Safe Mode.

There is also a comment from a deeply irritated user annoyed that his computer told him it was running counterfeit software and requiring him to spend an hour on the phone to support getting another activation key.
