No, this is not a mistake: Microsoft offers a small tool for changing the product key of windows xp or vista. Ok, they call it ‘updating the product key’, but that’s just a different word for it. In general, I like the idea.
More and more computers come preinstalled, having a recovery cd which is more or less just a disc image or an automated installer. But sometimes CDs break and/or you’re forced to use another installation medium.
As I’m trying to keep things legal, I need to activate windows for getting all the required updates. So I need to insert the right key. A small recherche took me to the following Link
This is the Microsoft Product Key-Updater which even activates your windows using the newly inserted key. Full service to get things right.
