title: Reassociate files types for visual studio 2012
body: <p>I've had an install of 2012 for a while, but I've had to also just install VS 2010. As expected, all my file associations now point to VS2010 and the icons aren't so intuitive. Without doing each file manually through the explorer menu, how can I quickly revert/change the associations back to VS2012?</p>
