Enabling tablet mode with Continuum in Windows 10 applies more to those who own a Microsoft Surface Pro 3 and you want to use it as a tablet. If you wish to use it in this way, you can open the Action Center icon that is on the lower right corner of the screen. There is a Tablet Mode button that will suddenly switch you to tablet mode. It’s like using Metro UI, but those that prefer to use their Surface Pro 3 as a desktop never go into Tablet Mode. It’s completely optional.
