Wasn't it somehow possible to go to "Installed Updates" and select Windows 7 and de-install it? And then Windows Vista would be back?
Or was that only in the Beta or was that even possible at all...?

No, it's not a software update, it's the entire operating system. When you upgrade from Vista to Win 7 there is nothing left of the Vista operating system to go back to. You'll have to save your data and do a clean install of Vista.
But, by the time the RC expires next year you should be able to buy an upgrade license for less than $200. Even an OEM copy of Vista Ultimate is only about $180 right now. Besides, 1 year is plenty of time to save up $200-300.
