Windows 2.0, released in 1987, was a version of Microsoft Windows graphical user interface that was said to look similar to the Mac OS, but was somewhat more primitive in comparison. The user interface was similar to the more recent Windows 3.0, and it had much more functionality than Windows 1.0. Specifically, version 2.0 allowed for windows to overlap each other, as Windows 1.0 required all windows to be tiled on screen. File management tasks in Windows 2 were still managed by use of the MS-DOS Executive program introduced in Windows 1, which was more list-driven than icon oriented.

Windows 2.0, also known as both Windows/286 and Windows/386, was soon followed by the more popular 3.0 version.

The first versions of Microsoft Word and Microsoft Excel ran on Windows 2.0.
