PC World posted a news story that a web site that leaked details of Windows XP Service Pack 3 claims that the update includes several new features, including some borrowed from Windows Vista.

According to NeoSmart Technologies, Windows XP SP3 build 3205, which was released to beta testers on Sunday, includes four new features among the 1,000-plus individual hot fixes and patches that have been issued since XP2's debut three years ago.

Features backported from Vista, said NeoSmart, include Network Access Protection (NAP), an enterprise policy enforcement technology that inspects client PCs before they access a corporate network, then updates the machines if necessary or blocks them if they don't meet specified security criteria.
