Can you help me with my software licensing question?

I am talking about during installation. Using regular licensing, not volume licensing.

Amongst OSes of the same class, are CD keys interchangeable or are they locked to a specific subset of CDs?

In other words: If I have 10 legally purchased copies of Windows 7 Professional, can I throw out the discs for all but one? And all the CD keys will work?

UPDATE: How about for service packs (when they come out). If I have Windows 7 Professional SP1 and a Windows 7 RTM original? Do they change CD keys between service packs?

Yes, you can interchange them. You can use a given license key with any media, 32 or 64-bit, for the same type of installation. If you try to activate a retail disk with an OEM key, or vice-versa, you may need to call the Microsoft activation hotline to complete the process. Service packs do not affect activation of legal copies of Windows.
