win 10 password problem

I updated to win 10 a couple of days ago and have been running OK until today. Now the machine will not start because the start up password will not be acceoted. When I enter the microsoft password to match the e-mail it says go to account.live,com/password/reset, but how do I do that if the computer will not sart.
.My wish now is to go back to windows 7 but this is impossible if the computer cannot be started.
Can anyone help

You are posting from another computer, it would seem, so you could access your Microsoft account there and check the password, or reset it if needed.

Thanks for your reply but the problem is now sorted This may sound strange but it was my wife who changed the password then went away for two days without keeping me informed. After a few words everything is back to normal and I am doing OK with win 10
