Today, support for Windows 2000 from Microsoft ends. Windows 2000 was released over ten years ago, on February 17, 2000. Although it may have had a shaky start as far as application compatibility goes, it is renowned as one of the most stable operating systems ever to come out of Microsoft, and it paved the way for Microsoft to merge the “home” (9x) and “business” (NT) lines of Windows with Windows XP, the following year.
