My administrative password is right, but startup repair says it's wrong

Hi,

A couple days ago, I updated my laptop by automatic online updates, and after that the startup screen (where I enter my login information) went dark, so I can't enter to my windows 10.

I proceeded to the boot section where I chose the advanced options for repair. All the options ask for my adminstrative acount's password. I entered the correct password, but it kept saying it's wrong. Using my cellphone I changed my microsoft password and
entered the new password several times running the boot, still it insists it's a wrong password!

I read lots of articles and troubleshooting advices, but none is working. I just want to enter to my Windows and I don't understand why it doesn't recognize the right password.

Could you please help me? Thank you.

Nice regards,

Hannaneh
