I rebooted my win 10 computer and when attempting to enter the pw, i could only enter the #'s in the pw. I figured a KB fail, checked for stuck keys...no luck, then opened the onscreen KB. Same problem. After trying and failing to enter the pw, windows 10 made me rebook and type a code: A1B2C3 which i did with no 6. I erased the code and entered my PW...the entire thing with no problems. But windows wanted the A1B2C3 code so i entered it. After, i tried to entery my but it would not let me entets the letters. Can anyone please help me or point me in a direction. I am clueless on where to start. No new hardware. The only software i added recently was trying to connect my phone to my computer.
