The main difference with Windows 10, which is first visible to the user, is the renewed visual appearance.
Applications, settings and file explorer can all be found in the Start menu at the bottom center of the screen.
The most important basic programs are attached pinned directly to the start view of the Start menu. All software installed on the computer can be found in the All > button in the upper right corner of the start menu.
You can pin your favorite app to the Start menu by right-clicking on it and selecting Pin to Start.
Logging out of Windows is done by clicking on the personal picture/name button in the lower left corner of the start screen of the Start menu.
