Windows Me (Millennium Edition) is an operating system from Microsoft, released commercially September 14, 2000. Windows Me was developed specifically for the home user, just as their Windows 2000 version was developed specifically for the business user. Microsoft claims that this Windows 98 update (which has a very similar look-and-feel to the earlier version) combines a more intuitive interface for the new user with added functionality for the experienced user.

Designed to be backwards compatible with Windows 98, Windows Me works with the earlier version's applications and drivers. Improvements over Windows 98 include functions to enhance system stability and error correction (what Microsoft is calling "PC health"), as well as features designed for digital media, home networking, and online experience:
