Wendell,
Can the Home versions be upgraded to the Pro versions.
Personally, this is a huge reason why I get frustrated with Microsoft. Make an OS. And, make it one size fits all. You know call it Windows 8 and be done with it. OK, so the bottom line, maybe you make more money. But, you make a lot of customers happy, and you avoid threads like this (a good thread and well done by Anil. If one day, Chris took over for Steven Ballmer or even better, Susan Bradley, the first thing they should do is get rid of the multiple OS. Or better yet, get ride of Windows 8 or put a start button on it or in the control button. Remember, Vista? What there were 76 versions? And, they were all on the same DVD.
