Windows 8.1

6

The second edition to the Windows 8 series (its predecesor was Windows 8), Windows 8.1 was released to address issues such as the Start menu,and user functionality between the desktop and touch-based systems like tablets.

This OS is more experimental as it attempted to adopt a new design language (Metro), styled after public transportation signs. Metro emphasized on simple, tiled geometric shapes, and large text to portray the idea of modernity and sleekness.

The Metro design language was outright distinct from the previous OS, estranging their audience from the familiar Windows Aero.
