Windows XP SP2 RC1 Adds Features

“Microsoft made a lot of changes to Windows XP Service Pack 2 between the beta stage in December and the Release Candidate 1 version that became widely available for download last week.
Most of the changes involve security, which makes sense because Windows XP SP2 is primarily a security overhaul of the Windows XP client operating system. But a few new features found their way into the service pack’s first release candidate.”
