Hello Tom, and welcome to Justanswer.com, my name is ***** ***** I will do my best to assist you.
Ive seen this happen before. To say the least, the Windows 10 initial setup can be a bit convoluted. Question, when you are being asked for your password.
Does it show an email address on the same page?
If so, who is that email account with. Gmail, hotmail, outlook.com, etc?
and also, have you tried using the same password ***** your email account uses to sign in?
Please test that out, and whether it works or not send a response.
I strive to provide great service, and greatly appreciate a rating of excellent ( 5 stars ) selected and submitted below this answer or at the top right of the screen. I always answer follow up questions.
