Technical reference for developers and articles for various Microsoft magazines such as Microsoft Systems Journal (or MSJ) is available through Microsoft's MSDN site, short for Microsoft Developer Network. MSDN also offers subscriptions for companies and individuals, and the more expensive subscriptions usually offer access to pre-release beta versions of Microsoft software. In recent years, Microsoft launched a community site for developers and users, entitled Channel9, which provides many modern features such as a wiki and an Internet forum.

Most free technical support available through Microsoft is provided through online Usenet newsgroups (in the early days it was also provided on Compuserve). There are several of these newsgroups for nearly every product Microsoft provides, and often they are monitored by Microsoft employees. People who are helpful on the newsgroups can be elected by other peers or Microsoft employees for Microsoft Most Valuable Professional (MVP) status, which entitles people to a sort of special social status, in addition to possibilities for awards and other benefits.
