Windows 2000

Windows 2000 (originally referred to as Windows NT 5.0 during beta) is an operating system released in February 2000 by Microsoft Corporation. It was the successor to Windows NT 4.0 and the predecessor to Windows XP and Windows Server 2003. Four editions were released: Professional, Server, Advanced Server, and Datacenter Server.

Features
Windows 2000 introduced NTFS 3.0, Encrypting File System (EFS), as well as basic and dynamic disk storage. A number of new assistive technologies were introduced for people with disabilities, and increased support for different languages was also introduced.

It also introduced many of the new features from Windows 98 and Windows 98 Second Edition that were previously unavailable to the Windows NT product line, such as the Windows Desktop Update, Internet Explorer 5.0, Outlook Express, NetMeeting, and native (albeit limited) FAT32 support among other features.

Windows 2000 also introduced to the Windows NT product line better support for DirectX, shipping with DirectX 7.0 as standard, but was ultimately capable of supporting up to DirectX 9.0c using the February 2010 redistributable, meaning it had limited capability for playing video games.
