Full Operating system Microsoft XP Pro

Designed for reliability, security and privacy, high performance, and ease of use, the Windows XP operating system provides a host of benefits for business and home users. A clean and simple desktop, rock-solid reliability, and easy-to-use features that take advantage of the digital age all contribute to the value of Windows XP. 
Enhancements in real-time voice, video, and data communications will allow the PC to become a center of communications and creativity beyond just e-mail and instant messaging. Windows XP will also allow the user to connect back to the desktop from any location, and support for new wireless networks will be built in.

FEATURES

Business-Level Reliability: Windows XP delivers a new level of stability, so you can focus on your work. For example, in most cases, if one program crashes, your computer will keep running. 

Advanced Performance: Windows XP manages system resources efficiently, to keep your system running as fast as possible even when you`re working with multiple programs at the same time.

Remote Desktop: Allows you to create a virtual session and use your desktop computer from another computer running Windows 95 or later, giving you access to all of your data and applications even when you`re not in your office.

New Task Based Visual Design: Get to your most commonly used tasks quickly, thanks to a cleaner design and new visual cues.

Wireless 802.1x Networking Support: Provides support for secured access, as well as performance improvements for wireless networks.

Windows Messenger: The easy way to communicate and collaborate in real time on your computer. You can see the online status of your contacts and choose to communicate with them through text, voice, or video with better performance and higher quality.

Encrypting File System: Provides a high level of protection from hackers and data theft by transparently encrypting files with a randomly generated key.

Fast Resume from Hibernation or Standby: Save battery power when you`re working on the road. With Windows XP your laptop can enter Standby or Hibernate faster, and it can start working again faster after resuming from Standby or Hibernation.

Help and Support Center with Remote Assistance: In addition to a comprehensive set of documentation, Help and Support Center in Windows XP includes Remote Assistance, which allows you to have a friend or IT professional who is also running Windows XP remotely control your computer to demonstrate a process or help solve a problem.

System Restore: If something goes wrong with your computer, you can revert the system back to a previous state.
