Hi, I have a window 8.1 machine with only a local admin user. Accidentally, the user id got locked due to three incorrect attempts and not i cannot get in to the machine. To reset the password, i tried to use the password reset USB from other machine as i cannot create from the same machine but it didn't work. I also tried to change the password through command prompt but 

Please suggest how I can reset the Password or unlock the userID of the local admin user.

Thanks,

Hi,

A locked-out account cannot be used until it is reset by an administrator or until the lockout duration for the account has expired.

If you remember the password,you may type the password after the lockout duration for the account has expired.

If you forget the password,please refer to the link below:
