Back in February, I wrote an article, Windows 7 Product Editions, in which I discussed the various SKUs (stock keeping units, or product editions) that Microsoft would provide with its next operating system. Now, with nearly fully-functional versions of each product edition available to the public, I thought I'd provide a series of tables comparing each Windows 7 product editon, similar in scope to the work I did documenting Windows Vista.

I believe these tables will help you pick which Windows 7 product edition makes the most sense for you, based on your needs and wants. Let's dive right in.


Note: This set of tables has been updated for the final, shipping versions of Windows 7. Unlike similar comparisons, these tables were generated using not by simply observering each product edition, but also by using Microsoft's internal reporting mechanisms to determine exactly which features are, in fact, available in each version. For this reason, I can reasonably state that this is the most complete and accurate list of Windows 7 features anywhere. That said, I'm still human and could have made mistakes transcribing the information. If you see anything wrong or missing, or would like to see a certain feature added, please contact me.
