The MCTS covering the configuration of Windows 7 is a great place to start your Microsoft certification path. That is because that exam applies to at least 3

PRO Exam 70-685: Windows 7, Enterprise Desktop Support Technician 7 on top of your MCTS in Windows 7 Configuration. The requirements to obtain the MCITP
Enterprise Desktop Administration 7 certifications are similar but you need to take the Microsoft PRO Exam 70-686: Windows 7, Enterprise Desktop
Administrator 7 exam on top of your MCTS in Windows 7 Configuration. I should note that both of these exams are listed as "in development" by Microsoft and
are expected to be released on November 16, 2009.
