"In addition, the Network Access Protection (NAP) framework enables system administrators to define and enforce policies that require network clients to establish their trustworthiness and compatibility with the network before being given a specified access. Developers use API-level access to NAP and the Windows Filtering Platform (WFP) to reduce user and administrator security workloads by providing application-specific security settings supporting Firewall and NAT transversal, allowing more detailed (down-to-packet-level) screening of data transmissions, and isolating and validating new tools and their configurations prior to fully installing and integrating them into a running system.
Reliability: Restart manager, I/O cancellation, app feedback
Windows Vista adds an extensive set of new APIs and developer services to make applications predictable and manageable including the Restart Manager, improved I/O cancellation support and the capability to integrate into the Windows Feedback Platform (WFP)."
