This guy has been around in the world of MS operating systems for a very long time, he developed one of the most useful suites for optimization, debugging and troubleshooting of windows OS the sysinternals suite, in fact his work is so important that despite having uncovered many flaws and pitfalls inside Windows he got a Job at the company and now is working full time at the Azure team. I highly recommend the article where he shares his view on the future of cloud computing between many other interesting facts.
