Kernel

The Windows 7 project involved very efficient software engineering planning and execution. It is no surprise that an equivalent level of efficiency exists throughout the OS (efficiency in how the OS deals with faults, threads, memory management, power management, process…

Dave Probert Windows Kernel Achitect Until recently Dave managed kernel development for Windows, including Windows 2000, XP, Server 2003, and early phases of XPSP2 and Vista.  Dave is currently working on a project to release kernel sources to universities and developing ProjectOZ, an…

Here's the second part of the interview with Neal Christiansen. He talks about the internals of Windows and how File System Filters work.Here's the first part of the interview in case you missed that.

The Fault Tolerant Heap (FTH) is a subsystem of Windows 7 responsible for monitoring application crashes and autonomously applying mitigations to prevent future crashes on a per application basis. For the vast majority of users, FTH will function with no need for intervention or change on their…

Here is the long-awaited demo of the latest incarnation of Singularity, a research operating system written primarily in safe C#. See Singularity III: Return of the SIP, here.

Here's the second part of Molly's interview, where she dives down deeper into Windows' cache manager.

In developing Windows 8, power efficiency was a primary engineering theme. This means that all aspects of the system were designed and developed with efficient power usage in mind. It's paid off—Windows 8 is the most power efficient version of Windows to date. In this video,…

A great deal of data is collected during the alpha and beta phases (aka the Developer Preview and the Customer Preview) of Windows. As with Windows 7, Windows 8 performance telemetry is invaluable for identifying performance bottlenecks and bugs in Windows running in the real world. There…

Charles Torre continues his series of "going deep in Windows" with an interview of Nar Ganapathy, an architect on the I/O Manager in Windows (part of the Windows Kernel).

Almost everything you do on your PC requires the assistance of NT's Object Manager. The Object Manager is a shared resource; a subsystem upon which all other executive kernel subsystems rely on to get their jobs done. That said, among NT's kernel components, the OM receives the least amount of…
