You will restore the device to its default settings and erase the internal storage. Before restoring the device, save your data and charge fully the device's battery.


Caution: if you reset your tablet without activating the Office license, you will lose the free license that was included with your device. You will need then to purchase a new license to use Office. So make sure to activate the provided license before you start resetting the device.
