Microsoft has countless products, and literally hundreds of millions of users. Our goal is to scan the Microsoft knowledge base, every day, and keep you up-to-date when new information is published, in the technologies you are interested in.
Of course, you probably know that already, since you were looking for a specific technology and didn't find it on our site. :)
There are a couple of reasons for this. If Microsoft "retires" a technology, we remove it from our knowledge base as well. our service uses the same service that populates the drop down list, on support.microsoft.com. Click the link below, and you'll be taken to the Microsoft knowledge base. Check the drop down options of products they support in their knowledge base. These should match the products in our knowledge base.
