Here is the deal. Long time ago (6 months or so) I installed windows 10 on my old laptop. Today I accidentally locked my stuff (new laptop, everything) at the office, so decided to go home and use my old laptop for work. However, I have already updated my windows profile with a new email and password, so when I turn on my old laptop I see the old account (I recognize it by the old email address) - as you can imagine, this old local account doesn't match with a new login info I use, so I now can't login to my old win 10 laptop. And obviously I don't remember th at old local account password.

Resetting password online on WI does official site doesn't help because it is asking to reset the password for my new email, not the old one.

How to fix that?
