Following are some of the Windows XP key features:

• The Internet's online environment is more closely associated with the
  Windows desktop.
  
• Windows XP provides extensive support for multimedia and digital imaging.
  
• The Start menu is more operational and hides little-used programs until
  you're ready to access them. The items you need are always at your
  fingertips. You can make menu changes on-the-fly without messy dialog boxes.
  
• Advanced system tools, such as the automatic update of Windows system
  files when they become damaged and a rollback feature that enables you to
  return to a more stable point in time, help protect your computer files and
  monitor your hardware.
  
• Improved hardware support features enable you to attach new devices, such
  as FireWire cameras, into your computer without having to set hardware
  switches or determine appropriate interrupt settings.
  
• Windows XP continues the tradition of online support and provides firewall
  protection from unauthorized access into your computer.
  
• Windows XP does most of the setup work for you when you want to network
  another computer to yours.
  
• You can monitor newsgroups and make postings from Outlook Express's common
  interface.
  
• Your desktop now becomes an online access tool that lets you access
  Internet Web pages as easily as you access your own PC's files.
