The Security Center lets you check the status of your essential security settings.

XP certainly looks different, with rounded window corners, larger and more detailed icons, and a clean-look desktop that on first installation shows only the taskbar and Recycle Bin. XP is also more customizable than earlier versions of Windows, and includes visual themes that let you change the whole appearance of Windows in an instant. That is the window-dressing, but underneath are some significant improvements. One of the most interesting is Remote Desktop. A standard XP feature, this uses technology from Microsoft Terminal Server to enable users to access their computer over any connection; for example, by dialing into the office from home.

This is not just file access--this technology lets you run applications remotely as if you were sitting at your desk at work. This is mature technology, stable and carefully thought out. So, for example, you can print from a remote word processor to a local printer. A variation on the theme is Remote Assistance, where the user can allow a remote helper to view their desktop, or optionally gain control of the keyboard and mouse, in order to troubleshoot a problem. The feature can also be disabled to ease security concerns.

The Information Bar in Windows XP Professional Edition with Service Pack 2 notifies you when it blocks ActiveX control or active content and then lets you decide what to do.

The most significant new feature for Internet users is the built-in firewall. A firewall protects against one of the most disturbing security risks, in which other users unknown to you might connect to your computer while it is online, reading private files or causing other damage. XP's built-in firewall is a simple affair, but it does prevent most types of unauthorized connection.

Windows XP has strong multimedia features. The new Media Player lets you copy music from CD to hard disk, create your own playlist, and write your own music CDs if you have a CD writer. Although there is loss of quality as a result of compression, the process is easy and convenient. Media Player 8.0 can play back DVD video, but only if a hardware or software DVD decoder is already installed. You can also play MP3 audio files and MPEG videos, but sadly, not the popular RealMedia formats. In the end, Media Player does nothing that you cannot also do with free alternatives, but it is slick and nicely integrated.
