Error message "User name or password is incorrect" at Win7 logon screen - three systems!

I have a home network with three Win7 machines. Today I introduced the third Win7 and replaced a WinXP machine. All three Win7 machines have been operating properly for months. Two machines had multiple admin users. One had an admin user added after the problem showed up.

There were some typical network issues - getting the machines to be able to access directories on other machines. That solved, I am now faced with this:

When each machine is turned on, we get a red cirle with an X, and this error message: "User name or password is incorrect."

Of course, at this point no one has tried to put in a password yet.

The system presents only one user account. It does recognize the correct password. When Win7 finishes load, we can then log off the initial user account and get to a proper user account choice page. At this point the system allows us to choose the account we want, accepts the appropriate password and lets the right user account load.

To recap. For All Three Machines:

Multiple user accounts

Choice of user accounts is not presented after bootup

Error message

Only one user account presented

After the first UA loads, the system behaves appropriately.

End of recap.

I have tried changing user accounts and network settings without success. Please help

Answer

Changing a user's password is trivial for malware or for a virus.

You can use the process below to invoke System Restore. This will set Windows (and its password file) back to the selected date:
System Restore
1. Set your BIOS so that it uses the DVD drive as its primary boot device.
2. Boot the machine with your Windows 7 Repair CD.
3. Press a key if prompted to boot from the DVD.
4. Select "Safe Mode Command Prompt" when prompted.
5. Log on as Administrator if prompted.
6. Select Repair when prompted.
7. Select System Restore when prompted.
8. Set Windows back to a point before this problem occurred.
9. When finished, remove the CD before rebooting the system.
In Step 2 you could also use your Windows 7 installation DVD. The subsequent steps are similar to the ones above.

A couple of observations:
- Rather than not setting a password, you should get Windows to remember your password. The process below lets you do this.
- Having a single account is obviously asking for trouble. After you have resolved the current problem you should create a second admin account, with a non-blank password, and record the details in a safe place.

Automatic logon
1. Click Start
2. Type the three letters cmd into the Search box and click OK.
3. Type this command and press Enter:
    control userpasswords2
4. Single-click your account name.
5. Untick the box that requires users to enter a password.
6. Click OK.
7. Enter your password when prompted.
