GoingDeep: ark Russinovich: Inside Windows 7

How has Windows evolved, as a general purpose operating system and at the lowest levels, in Windows 7? Who better to talk to than Technical Fellow and Windows Kernel guru Mark Russinovich? Here, Mark enlightens us on the new kernel constructs in Windows 7 (and, yeah, we do wander up into user mode, but only briefly). One very important change in the Windows 7 kernel is the dismantling of the dispatcher spin lock and redesign and implementation of its functionality. This great work was done by Arun Kishan (you've met him here on C9 last year). The direct result of the reworking of the dispatcher spin lock is that Windows 7 can scale to 256 processors. Further, this enabled the great Landy Wang to tune the Windows Memory Manager to be even more efficient than it already is. Mark also explains (again) what MinWin really is (heck, even I was confused. Not anymore...). MinWin is present in Windows 7. Native support for VHD (boot from VHD anyone?) is another very cool addition to our next general purpose OS. Yes, and there's more!

Tune in. This is a great conversation (if you're into operating systems). It's always great to chat with Mark.
