Description:  

Determines whether screen savers used on the computer are password protected.

If you enable this setting, all screen savers are password protected. If you disable this setting, password
protection cannot be set on any screen saver.

This setting also disables the "Password protected" checkbox on the Screen Saver dialog in the
Personalization or Display Control Panel, preventing users from changing the password protection setting.

If you do not configure this setting, users can choose whether or not to set password protection on each
screen saver.

To ensure that a computer will be password protected, enable the "Enable Screen Saver" setting and specify
a timeout via the "Screen Saver timeout" setting.

Note: To remove the Screen Saver dialog, use the "Prevent changing Screen Saver" setting.

Supported on: At least Windows 2000 Service Pack 1.

Result
By Default you have access to "On resume, display logon screen" under Start -> Control Panel ->
Personalization -> Screen Saver.
You can prevent users from using "On resume, display logon screen" using Group Policy or modify the
specific
registry key.  

Note: If you want to prevent a specific user from using "On resume, display logon screen" you need to
modify or add the
registry key under his SID.
