From Microsoft:

Today Microsoft launched @MicrosoftHelps, a new Twitter handle that provides customers around the world with help and information on Windows 7, in English.  Through this social medium, Microsoft will monitor and respond to real-time Windows 7 tweets and use them to improve the information, support and experience customers have with Windows 7.

Through Twitter, customers will have better access to help when, how and where they need it, key to Microsoft’s vision for customer support.  The @MicrosoftHelps team consists of experienced social media agents with extensive knowledge about support resources to get answers to customers questions. In addition to responding to direct tweets, they will monitor the Twittersphere and suggest resources to tweets about Windows 7 problems, issues or questions.

If anyone gets the Internet, it's Microsoft. :)
