I upgraded windows and after all installations it required to enter the PIN code but the keyboard does not appear on screen. What to do?
Have a look at the bottom left of your Task bar for the touch keyboard, if it isn\’t there right click on the taskbar and choose show touch keyboard, then launch from there. All of this is assuming you mean Windows 10 on PC as this is where you posted, and you are doing it on a tablet with no inbuilt keyboard, If you mean mobile, normally clicking in any place you type brings up the keyboard. Always helps to post in the right forum.
