The application process for Microsoft Research PhD Scholarships is open until 16th of September. The projects should be related to the following research fields by Microsoft Research in Cambridge:

As previous years, applications must be made by PhD supervisors not by students. Supervisors will be informed of the decision in January 2012 and will then have up to one year to find the best student for the proposed project. Students will typically start their PhD in October 2012.

You’ll find more information to PhD Scholarship here and a number of currently open PhD positions sponsored by Microsoft Research here.
