  Ennek inkább utána kellett volna járnod...

  "[I]...Service Pack 1
  Set Program Access and Defaults was added in Service Pack 1.

  Service Pack 1 (SP1) for Windows XP was released on September 9, 2002. It contains post-RTM security fixes and hot-fixes, compatibility updates, optional .NET Framework support, enabling technologies for new devices such as Tablet PCs, and a new Windows Messenger 4.7 version. The most notable new features were USB 2.0 support and a Set Program Access and Defaults utility that aimed at hiding various middleware products. Users can control the default application for activities such as web browsing and instant messaging, as well as hide access to some of Microsoft's bundled programs. This utility was first brought into the older Windows 2000 operating system with its Service Pack 3. This Service Pack supported SATA and hard drives that were larger than 137GB (48-bit LBA support) by default. The Microsoft Java Virtual Machine, which was not in the RTM version, appeared in this Service Pack. Support for IPv6 was also introduced in this Service Pack.

  On February 3, 2003, Microsoft released Service Pack 1a (SP1a). This release removed Microsoft's Java virtual machine as a result of a lawsuit with Sun Microsystems.

  Service Pack 2
  Windows Security Center was added in Service Pack 2.

  Service Pack 2 (SP2) (codenamed "Springboard") was released on August 6, 2004 after several delays, with an emphasis on security. Unlike the previous service pack, SP2 added new functionality to Windows XP, including a firewall, improved Wi-Fi support, such as WPA encryption compatibility, with a wizard utility, a pop-up ad blocker for Internet Explorer 6, and Bluetooth support. The new welcome screen during the kernel boot removes the subtitles "Professional", "Home Edition" and "Embedded" since Microsoft introduced new Windows XP editions prior to the release of SP2. The green loading bar in Home Edition and the yellow one in Embedded were replaced with the blue bar, seen in Professional and other versions of Windows XP, making the boot-screen of operating systems resemble each other. Colors in other areas, such as Control Panel and the Help and Support tool, remained as before.

  Service Pack 2 also added new security enhancements, which included a major revision to the included firewall that was renamed to Windows Firewall and is enabled by default, Data Execution Prevention, which can be weakly emulated, gains hardware support in the NX bit that can stop some forms of buffer overflow attacks. Also raw socket support is removed (which supposedly limits the damage done by zombie machines). Additionally, security-related improvements were made to e-mail and web browsing. Windows XP Service Pack 2 includes the Windows Security Center, which provides a general overview of security on the system, including the state of antivirus software, Windows Update, and the new Windows Firewall. Third-party anti-virus and firewall applications can interface with the new Security Center...[/I] forrás: http://en.wikipedia.org/wiki/Windows_XP"
