I am running Windows 7 Professional.
I have one admin account and two standard users. The admin account and one of the standard accounts are password protected. The other standard account is not password protected, nor has ever had a password.
This morning while attempting to login to the standard account without the password, it suddenly asked for a password. I tried entering several different passwords to no avail.
Can I please have a reason why it happened like this and how to fix it?
