Improved management mechanisms. Windows Vista and Windows Server Longhorn implement the Windows Hardware Error Architecture (WHEA) to provide a common operating system/hardware error-handling infrastructure that builds on PCI Express Advanced Error Reporting (AER). In addition, the registry and services model have both been enhanced for better performance, security, and manageability.
|
| • |
New mechanisms for controlling registry reflection. Windows Vista introduces the concept of ownership for registry keys to help reduce collisions between 32-bit and 64-bit applications.

I/O completion and cancellation routines are often difficult to implement and prone to race conditions. The Driver Hang Verification feature of Driver Verifier in Windows Vista Beta 1 measures how long it takes a driver to complete and cancel IRPs in user-mode applications.
Listen to Jeff Meng, Paul Sliwowicz, and Gerald Maffeo from the Windows Reliability team talk about I/O cancellation on Channel 9.
See also Kernel-Mode Fundamentals papers about cancel logic and handling IRPs.
