Topic: How to install a Vista upgrade on any PC

Unadvertised sale: Buy an upgrade, get a stand-alone version
The Register

Microsoft is running an unadvertised sale on Windows Vista. For the price of an upgrade edition requiring an existing copy of Windows, anyone can have a stand-alone version of Vista that will run on any PC. Indeed, the upgrade editions are full versions, simply waiting to be told to install themselves regardless of what OS is currently on the system, if any. The trick is all in how you interact with the setup program.

So in reading this and the LINK (this recent article) in the story, does it mean that you can install Vista from the CD, and I'm assuming that it means anyones, and if you follow the instructions, you can have Vista installed for 30 days without having to validate it, before you start losing bits of it.
As you all can see, I'm a complete "numpty" when it comes to software, (stop laughing) at least I admit it.

What's the point of using someone else's copy of Vista for 30 days, or am I missing something?
