Windows 10's Tablet Mode provides a more touch-friendly experience by making all applications run at full screen (instead of in windows) and giving you a Start screen instead of a Start Menu. If you have a 2-in-1 device, Windows 10 asks you if you want to enter tablet mode any time you convert your notebook right into a slate.
However, if you want to switch between Tablet and Desktop modes manually, stick with Desktop mode even on a tablet or steer clear of the prompt and also have it change to tablet mode automatically, you can change the settings. And when you need to only use the on-screen keyboard, read this separate guide.
Configuring Tablet Mode involves three basic actions:
Go towards the Tablet Mode tab under Settings -> System.
Toggle the "make Windows more touch friendly" option on or off.
Select whether the device switches modes automatically, prompts you or never switches.
