Microsoft Office XP is a productivity suite written and distributed by Microsoft for their Windows operating system. Released on March 5, 2001, it is the successor to Office 2000 and the predecessor to Office 2003, and was known as Office 10 in the early stages of its development cycle. Despite the "XP" branding, Office XP does not require Windows XP or higher; rather, "XP" was a marketing term for its era.
