Windows 10: I'm locked out of my windows log in. How do I get back in?

I just reinstalled my windows back in my laptop after using Ubuntu. Now my laptop, in windows OS, has a password I did not set up. Now I am locked out and I don't even know the password "my account" had. To be able to change the password on my windows, it's asking me to enter the old password which I don't even know. I have the email. Can you guys just send me the windows account password change link to my email? This is such a hassle.
