"This series has so far covered Windows Vista kernel enhancements related to processes, I/O, memory management, system startup, shutdown, and power management. In this third and final installment, I take a look at features and improvements in the areas of reliability, recovery, and security.

One feature I'm not covering in this series is User Account Control (UAC), which comprises several different technologies, including file system and registry virtualization for legacy applications, elevation consent for accessing administrative rights, and the Windows^® Integrity Level mechanism for isolating processes running with administrative rights from less-privileged processes running in the same account. Look for my in-depth coverage of UAC internals in a future issue of TechNet Magazine.

Windows Vista™ improves the reliability of your system and your ability to diagnose system and application problems through a number of new features and enhancements. For example, the kernel Event Tracing for Windows (ETW) logger is always active, generating trace events for file, registry, interrupt, and other types of activity into a circular buffer. When a problem occurs, the new Windows Diagnostic Infrastructure (WDI) can capture a snapshot of the buffer and analyze it locally or upload it to Microsoft support for troubleshooting."
