The word 'upgrade' here doesn't mean anything. These are full ROMs. An 'upgrade' isn't really possible with any Windows PDA, only a full reinstall. So these are all full versions.
Just a suggestion, if your only answer to someone asking for help is going to be "use the search n00b!" then I would suggest simply not answering at all. One of two things will happen after that, either the person asking the question will use the search on their own and find the answer after no one responds to the question, or someone nicer will come along and go ahead and answer the question for them.
