Windows 10 local administrator deleted, can't log in

First of all I'm new here, i have been using Windows 10 for last 2 months and i had no issues with update but few days ago i had a problem with opening applications . It says "App cannot open ,you're using inbuilt account sign in with Microsoft account " something like that so i googled about this problem and i have followed all steps but accidentally i deleted the local administrator and now I can't sign in into my pc , i know my password and pin code but it says "Your password was changed on a different device.You must sign in to this device once with your new password,and then you can sign in with your PIN " I don'know how to fix this , please help me and sorry for my bad english :)

Hi There

If your account is a local account stored on the Computer you can get and Pc company to reset the password for you with simple software.

if the account is a microsoft account then you can use the microsoft website to reset the password via email or Phone.

Hope This Helps
