forgot username password, what now?

Hi guys.
On my Surface Book after booting it asks me to input old password and new password, but I forgot old password so I am stuck at username welcome screen.
I found one trick which has to do with booting to safe mode,but for some reason my Surface Book is not showing picture in safe mode.
So is there a way to delete/ reset completly password input request, or any trick so I can log to Windows normally without asking for password?
I don't need, and want any more passwords.
Probably previous owner had password and I input my own one but forgot which I input.

Hmm I don't see how this is helpful, cuz it asks me to know my current password, which I don't know.

No, it doesn't in the relevant option.

Read carefully. Option 2 local accounts- via built-in administrator acct.

Else MS account as appropriate.

Which do you use?

And thank you for your reply.

It is not Microsoft account password it's a password to login to laptop.
I simply forgot what password did I input.
Strange, I just turned it on, and did not asked to input password.
So Surface Book is goging crazy.

So, I want to delete any password request at login, don't need it, how do I do it?

From the searchable Tutorials section (do feel free to have a look) I found this for you:
Sign in User Account Automatically at Windows 10 Startup

Thank you...Surface is going crazy, now not getting picture at all, just black screen....
