Windows XP analyzed the performance impact of visual effects and used this to determine whether to enable them, so as to prevent the new
functionality from consuming excessive additional processing overhead. You had the ability to lock the taskbar to prevent accidental changes. Fast user
switching allows users to save the current state and open applications of their desktop and allows another user to log on without losing that information.
The ClearType font rendering mechanism was designed to improve text readability on liquid crystal display (LCD) and similar monitors, especially
laptops. There were several features removed from Windows XP like. CD Player, DVD Player and Imaging for Windows were removed. Windows
Picture, Fax Viewer, Windows Media Player and Windows shell took over their duties. NetBEUI and NetDDE were not installed by default. Data Link
Control (DLC) and AppleTalk network protocols were removed. Plug-and-play–incompatible communication devices are no longer supported.
As Windows XP became popular with consumers, Microsoft began releasing Service Packs to add/remove features and install bug fixes. Service pack 1
added USB 2.0 Support, Microsoft's Java Virtual Machine (later removed in SP1a due to a lawsuit with Sun Microsystems), .NET Framework and
additions to the upcoming Windows XP Media Center Edition. The most important addition was the Default Programs section in control panel. In the
case United States vs. Microsoft Corporation, the court ruled Microsoft had to provide the ability for OEMs to bundle 3rd-party software with the same

Service Pack 2 was released to focus on Privacy and Security. Wireless Protected Access (WPA) encryption compatibility, improved Wi-Fi support (with
a wizard utility), pop-up ad blocker, Windows Firewall, Security Center, and partial Bluetooth support were added to Windows XP. Messenger was
disabled by default to prevent Ads from popping up through the Messager Service. Security Center could now monitor 3rd-party security programs.
Service Pack 2 removed Program Manager and support for TCP half-open.
Service Pack 3 was released to focus on the Windows XP 32-bit operating system. It added more features like the NX APIs for application developers
that enabled Data Execution Prevention for their code, independent of system-wide compatibility enforcement settings. Turned on the black hole router
by default to help prevent Denial of Service (DoS) attacks. Network Access Protect was included that would check if the OS, Anti-Virus, and Firewall are
up to date to allow access to the network. If NAP found an issue, it would prevent the PC from accessing the network. This was an added security to
ensure the PC had the latest security patches. The Energy Star logo and the address bar on the task bar were removed. There have been many other
fixes and updates.
Windows XP was a major advance from the MS-DOS based versions of Windows in security, stability
and efficiency. It introduced a significantly redesigned graphical user interface and was the first
version of Windows to use product activation in an effort to reduce copyright infringement. The
operating system was codenamed "Whistler" until early 2001 when Microsoft announced they were
going to name it "Windows XP", which is short for "Windows eXPerience" to highlight the user's
