Microsoft's Overview of Windows XP
Windows 2000 represented an important milestone in operating
system reliability and availability, due in large part to its 32-bit
computing architecture and fully protected memory model. With Windows
XP, Microsoft builds on that foundation by adding features and improvements,
such as better application and hardware compatibility, and new features
like shared DLL support, system restore, and device driver rollback.
The benefits to home users and system administrators alike are clear:
Fewer critical problems occur, problem resolution is faster and easier,
and personal computing is a more reliable and productive experience.
