The scenario is as follows:
I have one genuine "Ultimate" pre SP1 product key and one genuine "Home
Premium" pre SP1 Product key.
Both machines have the RC2-SP1 installed and the key were of course
activated before the RC2-PS1 install.
I am told RC2SP1=SP1 final release but some sources state this not to be the
case.
Therefore what I'd like to do is to start afresh with both machines
utilising the new SP1-DVD and use the "old" product keys to activate.
