How do you select an iTunes library on a PC?

[EatMoreCarrots]

I know the trick on a Mac is to hold the Option button while starting iTunes... but can anyone tell me how you do this in iTunes on a Windows machine? I'm sure the answer is already somewhere in this forum, but I've searched for a while now without finding it...

Try holding the shift key down when you launch iTunes. Then select "Choose library-" button.
