Going deep into Windows

Microsoft has a discussion forum called Channel 9 where MS developers discuss about MS products. this really is a cool place to know these products from perceptive of the people who have developed them. It include videos as well. I just visited a topic called "Going deep into Windows". this is a 4 part video series. If you want to understand how Windows works, you must see this. The video features Dave Probert, Windows Kernel architect who explains the Windows NT architecture in very detailed and sophisticated manner. This is the best explanation i have seen so far. Dave here explains the architecture in comparison with UNIX. Processes, threads, multiprocessing, concurrency ... I wonder how these concepts can be so simple. Dave really is a great teacher. This video has really changed my thinking in looking at OSs. great job done , Dave !
