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. It’s early yet, and things will no doubt change, so I’ll be updating these tables as needed going forward. But even at this early stage, 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.
