SUMMARY

One can use CTRL +ALT + DELETE keys to log on to a computer before users log on ensures that users are communicating by means of a trusted path when entering their passwords.

SYMPTOMS

Requiring CTRL +ALT +DEL before users log on ensures that users are communicating by means of a trusted path when entering their passwords.
If this policy is disabled, any user is required to press CTRL +ALT +DEL before logging on to Windows (unless they are using a smart card for Windows logon).On the other hand if this policy is enabled a user is not required to press CTRL +ALT +DEL to log on, but this  leaves users susceptible to attacks.

RESOLUTION

1.Click Start button and then click the Run menu.
2.In the Run menu, type-control userpasswords2 and click OK or, press the Enter key.
3.Click the Advanced tab.
4.Put a tick mark against the box with a dialog Require users to press Ctrl + Alt +Delete under Secure logon.
5.Click OK or, Apply.
6 Restart computer.

MORE INFORMATION

One can also try by turning off using the Welcome Screen [ Uncheck the box against the dialog Use the Welcome Screen. To do so open Control Panel, click User Accounts>Change the way users log on or off under Pick a task. This will lead to use a classic log on prompt which requires users to type a user account name.
