"but since when do I need to acquire a right..."
That depends on what you mean.
If you mean downgrade using media you have with an unused key, this
does not apply since you already have an unused license for Windows
XP.
An example:
I have a retail Windows XP Pro installed on my kids computer thus the
license is in use and not available to install on another computer.
But if I have a Windows Vista computer with the downgrade rights, I
can install my Windows XP also on the Vista computer, replacing Vista.
I end up the single Windows XP license installed on two computers with
the Vista not installed but the license accounts for the second
Windows XP installation.
