OS

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…

Here, we continue our exploration of the morphology of Windows 7 on Going Deep with windows kernel architect Dave Probert. You may remember him from an early four part episode of Going Deep where he teaches us about general purpose operating system architectures and history: Part 1,…

Charles Torre (interviewer) and Michael Lehman (cameraman) continue the "Going Deep: Windows" series with a discussion with Landy Wang, a developer of the oh so important Windows Memory Manager.Sorry for the low audio volume.EDIT November 2, 2008: There is no streaming video for this…

Drawbridge is a research prototype of a new form of virtualization for application sandboxing. Drawbridge combines two core technologies: First, a picoprocess, which is a process-based isolation container with a minimal kernel API surface. Second, a library OS, which is a version of Windows…

File System Filters are kernel-mode non-device drivers that monitor inbound and outbound FileSystem IO.A prime example of an FSM is anti-virus software (the primary function of an AV app is to monitor IO stream content looking for virus patterns, after…

What happens, exactly, when you turn your computer on? Yeah, you see the black screen and words scroll by, then, finally, the Vista startup sound... But, there's a good deal of code that runs in this preOS environment, much of it composed in languages you've probably never written (like 16-Bit…

In this second part of the video with Windows' kernel architect Dave Probert, we get a little tour of multi-threading and how Windows works at a deep level.

Dave Probert is an architect on the Windows Kernel team. This is the first time we've had an architect from the kernel team on Channel 9.You'll hear from Dave over the next week or so (we split the interview up into four parts).This is also the first of a series of deep looks inside Windows.

Charles Torre again sits down with some of the people behind MSR's Singularity research OS. This time, we drill down into the architecture of Singularity and discuss design decisions, usage of safe code, Channels, SIPs, etc. We even manage to get Galen Hunt, the OS Guy, up to the white…

At any given point, Windows is executing a lot of code. Some of this code runs in the background as services. In pre Windows 7 operating systems some services were set to auto run even though the configuration of the system (installed apps, hardware, etc) did not warrant them running. This had a…
