So, if you are seeing the message 'Press Ctrl+Alt+Delete or use the Windows Security Button to sign in' it looks like that is the best you can do. To try to simulate your problem scenario. In fact, my TK had popped up earlier in a simpler scenario but I arranged this
Then I was able to close the OSK and when I had chosen my account (with my mouse ICIM) then the TK popped up for me to use. To unlock my tablet now, I have to press the icon in the lower left of the lock page and have the native 'on screen keyboard' pop up and use that, however it's really awkward to use.įWIW I only had to use that to do a Ctrl-Alt-Delete.
