(a) If you've just installed Win 7 - why would you bother? The registry is new. What's the problem?
(b) why would you bother defragging the registry anyway? The hives sit tight - changes are a minute line of text here and there. Way over-kill
(c) I have never seen a tiny bit of data or research which indicates a registry defrag serves any purpose whatsoever - neither that it speeds anything up nor that it avoids problems - the best it can do is probably CREATE problems.
Be happy - leave the registry alone!
