Today, there were numerous short power outages in my area. About 7 over 20 minute period. Tried to start windows 7 pro and would not start. Automatic diagnostics could not fix the issue. I declined system restore and did hard reboot instead.
Windows 7 pro loaded but asked me for a password. I did not have a password set up. Before, when promoted for a password to perform changes, the screen would display my user name (Dell T7500) and a blank password field. Pressing enter with that blank password field allowed for changes as administrator.
I don't think that I had to enter user name and password to get in after Windows loaded before. Now I do. Again, no password was set for the only user. I am now presented with a user login screen for user Dell T7500. Now when I hit enter with a blank password field I get message that says user or password incorrect. No other user is set up and no password should be required for user Dell T7500.
Perhaps the auto startup diagnostics routine and the subsequent windows diagnostics caused this issue.
I hate to take the thing apart and cancel bios/cmos passwords by taking out the module and not sure that is what is needed. I think I need password help at the OS level. Help!
