To answer your title question: No, Super User is open to any format, technology, company product, or anything computer related.
As to that question: Your original tone of the original post really gave off a rant feel. That is not accepted by users well and is discouraged on Super User. You are looking for help by asking a question, so it is a good thing to make people feel like they want to answer your question. We also want quality questions and answers on Super User.
As to the close reason: I have to agree with the close reason to a degree, because what you are asking for is pretty much a tech dictionary specific to Microsoft. I do not think something like that even exists. The best thing I can think of is their support forums and the related parts of their website and looking up a particular term or idea your looking for.
