List of Microsoft Windows versions

It was first launched in 1985 as a graphical operating system built on MS-DOS.

Upon the release of Windows 10 in 2015, the ARM-specific version for large tablets was discontinued; large tablets (such as the Surface Pro 4) were only released with x86 processors and could run the full version of Windows 10.

Windows 10 Mobile had the ability to be installed on smaller tablets (up to nine inches);[16] however, very few such tablets were released, and Windows 10 Mobile primarily ended up only running on smartphones until its discontinuation.

Microsoft originally announced the Surface Hub, an interactive whiteboard, in January 2015.

Beginning with Windows Vista, all tablet-specific components were included in the main version of the operating system.
