Occasionally the office of the CTO, David Vaskevitch, sits down with some of Microsoft’s most influential technical employees to capture their stories. Instead of examining specific technologies, BTC takes a closer look at the person, the career and what it takes to produce world-class software.  Rob Short is an operating system pioneer. He helped Microsoft transition from the 1980s with DOS and 16 bit windows into the 32 bit world with Windows NT in the 1990s. More recently, Rob was part of the team that further enhanced windows to take advantage of the 64 bit processors of the new millennium. Today he is the Vice President overseeing development of windows kernel and virtualization technologies. This episode of "Behind the Code" is hosted by software architect, Keith Kaplan.
