Hi,
The interface that you are seeing is the tablet mode. You may simply turn it off to get the normal desktop mode.
There are two ways you can do it.
1. From the action Centre, near the date and time, click on the notification center. Now click on tablet mode to turn it off.
2. By clicking the magnifying icon in the task bar, Type Tablet mode
and simply turn off the tablet mode settings.
Hope this helps. You may get back to us for any further queries that you face on the issue above. We are happy to help!
