Disable CTRL+ALT+DEL requirement for logon
Computer Configuration\Windows Settings\Security Settings\Local Policies\Security Options
Determines whether pressing CTRL+ALT+DEL is required before a user can log on.
If this policy is enabled on a computer, a user is not required to press CTRL+ALT+DEL in order to log on. Not having to press CTRL+ALT+DEL leaves the user susceptible to attacks that attempt to intercept the user's password. Requiring CTRL+ALT+DEL before logon ensures that the user is communicating by means of a trusted path when entering their password.
If this policy is disabled, then any user is required to press CTRL+ALT+DEL before logging on to Windows (unless they are using a smart card for Windows logon).
This policy is disabled by default on workstations and servers that are joined to a domain. It is enabled by default on stand-alone workstations.
