Computer Configuration\Administrative Templates\Windows Components\Windows Logon Options Description
This policy controls whether the user's password is included in the content of MPR notifications sent by winlogon in the system. If you disable this setting or do not configure it, winlogon sends MPR notifications with empty password fields of the user's authentication info. If you enable this setting, winlogon sends MPR notifications containing the user's password in the authentication info.
