What is the diffrence between win2000 and windows XP

Windows 2000 is an earlier version of the Microsoft Windows operating system than Windows XP and is no longer supported by Microsoft. Generally, XP has better built-in device support, a snazzier user interface, and additional functionality. It is also the first Windows OS I've used that hasn't required the computer to be rebooted on a daily or weekly basis to resume normal operation. The differences are numerous. Is there something specific you're wondering about?
