Windows XP Professional integrates the strengths of Windows 2000 Professional， such as standards-based security， manageability， and reliability， with the best business features of Windows 98 and Windows Millennium Edition， such as Plug and Play， simplified user interface， and innovative support services. This combination creates the best desktop operating system for business. Whether your business deploys Windows XP Professional on a single computer or throughout a worldwide network， this new operating system increases your computing power while lowering cost of ownership for desktop computers.
For instance， by intelligently monitoring CPU state， Windows XP Professional can reduce the amount of power it is using. The operating system will provide more accurate data on the amount of power left； this will prevent the system from shutting down prematurely. Also， by allowing for the system to wake up as the battery nears a drained state， the computer can be put into hibernation， and save work in progress. Power management can now be set for each computer， or each user on a computer.
Improved security features in Windows XP help you protect yourself and your computer when you are online. With support for the latest security standards and enhanced virus protection， Windows XP protects you from some of the more common types of Internet attacks. As new viruses and problems arise， Microsoft is committed to delivering timely updates to help maintain the security of your computer.
It's a good idea to install Windows XP while you are connected to the Internet. This way， you have immediate access to all the current security updates available from Microsoft. During installation， you are prompted to download the latest updates to Windows XP.
