do this, when your computer is booting up and loading press f8 a bunch of times and go into safe mode when you get to the login screen click the administrator icon and you can login and change the pass like that

I discovered that the reason I couldnt get in was because I use numerals. I had to hit the Num lock keys in order to type in my pass. For some reason in the past, I never had that problem. But, it was by accident that I discovered that when id did not press num lock key, my typing would bounce off my login icon and go to someone elses. Pressing num lock resolved my issue.
