Log Into Windows 10 Without A Keyboard
Sometimes you might need to log into a Windows machine without a keyboard. A damaged keyboard, non-functioning ports for connecting an external keyboard, or a faulty keyboard driver could put you in this predicament.
Windows 10 includes an accessibility menu called 'Ease of Access', located in the lower righthand corner of the screen. This menu includes an on-screen keyboard. Use it to log in when your keyboard doesn't work.
