Start Menu is a part of the Windows user interface and was first introduced on Windows 95. Over the years, Start Menu provided quick access to installed applications and system settings. The Start Menu went through several changes, but it was completely redesigned for Windows 10.
The latest version of Start Menu comes with alphabetically organized installed applications in the left pane. The right pane is reserved for the pinned items and Universal apps. In order to organize your pinned apps batter, you can group them into folders or even resize the Start Menu in order to pin more Universal apps.
It’s worth mentioning that Start Menu on Windows 10 and 8 supports a full-screen mode that is optimized for tablet devices.
