After successful installation of Win 8 & several restarts, it comes up with a new log in screen.

The log in screen lists my name & under it my Email address.

It doesn't give me a chance to enter a user name or change user.

When I type in the password that worked before, it says it is invalid!

What do I do now?

I am 83 years old & have been on computers since DEC PDP 8e.
