Windows 11 launched on Oct. 5, 2021.

The biggest change seems to be the new look 'Taskbar icons' in the middle & the rounded edges of the windows, otherwise Windows 11 remains operationally the same as Windows 10.

The 'Start Menu' has also changed as has the simplified ribbon along the top of the 'File Explorer'.
