Windows 2000 build 2195.1

This is the official RTM build for Windows 2000, the last NT-based operating system geared solely at small business and enterprise. Five service packs were planned, however, only four were actually released followed by an Update Rollup. This release includes Internet Explorer 5 (upgradable up to IE 6) and DirectX 7.0 (upgradable to 9.0c). It was supported up until 2010.
