For most people who have fast (broadband) connexions to the Internet, and have called their ISP’s tech support, that line is quite ubiquitous. However, I have to report that doing it actually solved something for me!
Playing around with a new tablet, I made a discovery: If you press the “volume up” button and find that Microsoft Narrator opens for no reason, that means the Windows button on the front of the bezel is “stuck”.
Press the volume up button again to close Narrator. Then, tap the Windows logo on the case several times (you should switch back and forth between the Start screen and Desktop) to clear its state. Press volume up again and it should work normally.
