With Windows 10, Microsoft has tried once again to create a universal OS for tablets, smartphones and the classic Desktop PC. This unification started earlier with Windows 8, but it was not a successful attempt. With Windows 10, Microsoft has only slightly tweaked the UI but hopes to achieve success again. To achieve that goal, Microsoft has added the ability to detect on which display Windows is being used and switch between tablet and desktop mode.
What is Tablet mode in Windows 10
With Tablet mode enabled, Windows 10 becomes more touch screen oriented. For instance, it changes the behavior of the Start menu and turns it into a fullscreen Start experience. Take a look at the pictures below.
The "Desktop" Start menu in Windows 10 looks like this:
Compare it with the one when Tablet mode is enabled:
It also changes the behavior of the Notification Center. In Desktop mode, it pops up from the bottom, but in Tablet mode it appears from the right, like the Charms bar in Windows 8.
When you start some modern app in Tablet mode, e.g. the Settings app, it will be opened full screen:
Unlike Desktop mode, in Tablet mode, Modern apps do not have minimize, maximize and close buttons visible on the screen. To show them, you need to move your mouse pointer to the top edge of the screen. It will make the titlebar visible:
And so on. So, Tablet mode is designed to replace the Modern/Metro part of the Windows 8 UX.
How to enable or disable Tablet mode in Windows 10
You can switch between Tablet mode and Desktop mode in Windows 10 using two ways:
Enable Tablet mode via the Settings app
You can enable Tablet mode via the Settings app. Open it and go to System -> Tablet Mode. There you will find the appropriate switch:
The second option is the new Notification center feature.
Enable Tablet mode using Notification Center
Click the Notification Center icon on the taskbar to open it. There you will find the "Tablet mode" button which is a part of Quick Actions. Toggle that button to switch between Tablet mode and Desktop mode in Windows 10.
Tablet mode in Windows 10 looks like a good replacement for the Modern UI implemented in Windows 8. Finally, the end user can choose between a full screen UI vs a non-full screen UI. In Windows 8/8.1, the Start screen was always full screen and could not be disabled natively.
