 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. |
