Microsoft Windows XP Professional Upgrade with Service Pack 2 - PC Games

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 Home Edition with Service Pack 2 notifies you when it blocks ActiveX control or active content and then lets you decide what to do.

For Web browsing, XP comes with Internet Explorer 6.0. The enhancements in IE 6.0 are mainly of interest to Web developers, and in any case Microsoft makes IE freely available to all Windows users. Although Java is not installed by default, it is not difficult to download a Java Virtual Machine (JVM). Windows Messenger, originally a chat client, has evolved into a collaboration tool that allows for video conferencing and application sharing.

Service Pack 2 allows users to instruct Internet Explorer how to handle downloads from a specific publisher

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.

The XP user interface is not a radical departure from earlier versions of Windows, but there are a number of small changes that together add up to a significant improvement. The Start menu now automatically features the most frequently used programs at the top of the list, and you can add and remove shortcuts by right-clicking the icon and selecting Pin or Unpin from the pop-up menu. Windows online help is integrated into a Help and Support Center that works like an internal Web site, with searchable help, tutorials, and walk-throughs.

Windows XP Professional includes all the features of Windows XP Home, and adds support for dual processors, encryptable file systems, offline folders, the Remote Desktop as described above, and extra administration features that come into play when connected to a Windows server domain. XP is demanding on hardware, and it would be a mistake to install it on less than Microsoft's recommended minimum requirements. There is also activation to consider, a mildly annoying anti-piracy measure that requires you to obtain a code from Microsoft for full installation, and in the future if you reinstall or make major system changes.
