If you write code on Windows or like to know what goes on under the hood in Windows, then you've no doubt heard of Mark Russinovich . He's an OS kernel expert and a co-founder of Winternals ; a company that produced must-have operating system and development utilities for Windows (Winternals is now a Microsoft subsidiary as we purchased them in July, 2006. Yay!).Mark is now a Technical Fellow in Windows and is a member of the Windows Core Architecture team (you met some of the other big brains on the CoreArch team last year).Here we talk frankly about Mark's history, his coming to Microsoft, Windows security, what the CoreArch team does, what his role is, etc. Tune in.
