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.
