If the account your currently using is admin open an elevated command prompt and enter the following command
Code:
net user ("enter username") *
replace enter username with the username and remove parenthesis. after this enter new password twice.
If your account uses a Microsoft account use the password of the Microsoft account or reset it.
If none of these are available youtube's always a great source for ways to get into your account.
hopefully I could help sorry if I couldn't hope you have a great day,
