Thanks it worked for me. I was looking for the solution while doing some of my Android development work in Windows 7 bootcamp.

Doesn't work for me. "Windows filesystem verification failed. Please repair windows volume and try again" . But my windows is new, never used

Camptune X supports only Lion and below, this tutorial is irrelevant for Mountain Lion, this is highly requested by many users but there is no solution. Be the 1st and get my full appreciation.
