Windows workstation operating systems: 7, 8, 10
The most striking and obvious difference between Windows 7, Windows 8, and Windows 10 is visual: the start menu. See the images in the section below for examples.

Aside from interface changes, each new version of Windows is more secure than the previous version, and ships with more security settings enabled by default, while at the same time adding new features and increasing performance.



Windows 7 retains the classic start menu but applies a modern transparent theme to it.

Windows 8 and 8.1 have replaced the start menu with a fullscreen start page consisting of tiles instead of shortcuts or links.

Windows 10 brings back the start menu due to popular demand, while retaining some of the aesthetic cues from the Windows 8.1 start page.
