The operating system is one of the most important programs on your computer.
Every PC must have an operating system to run other programs. Operating systems perform basic tasks such as recognizing input from the keyboard, sending output to the monitor, keeping track of files and directories on the hard disk, and controlling devices such as optical drives and printers. Operating systems also manage how your computer accesses available networks.
Your new Dell system is offered with one or more versions of Microsoft Windows Vista®, touted by Microsoft as its most secure, highest quality release of a Windows operating system ever. You may also choose a version of Microsoft Windows XP, the previous generation of Windows operating system, which is still widely deployed in many business settings. Use the "Recommendations" and "Compare Side-by-Side" tabs to help make your selection.
Windows Vista® Downgrade Service
With Windows Vista® Downgrade Service from Dell, you get a simple way to migrate to Windows Vista on your schedule. Dell will automatically factory-install Windows XP Professional and give you the DVD to install Windows Vista Business or Windows Vista Ultimate when you’re ready (you will also receive the Vista Resource DVD). Dell will also support both operating systems on your PC throughout the limited warranty period.
