In windows you can disable the usage of ctrl+alt+delete before logging in.
{Via netplwiz or user controlpasswords2 then advanced will give you a window with at the bottom of it this option}.
Is there any possibility that this is able to be done using cmd or powershell?
I have been looking for a solution for about 3 weeks without any success.
Method 3: Via User Accounts Advanced Settings. Click on Start button, and type netplwiz into Start Search box, and hit Enter to open the User Accounts dialog box. Go to Advanced tab. Under “Secure logon” section, select and check the checkbox for Require users to press Ctrl+Alt+Delete option. Click Apply or OK.
mic84From TechNet: You need to change the registry value

Registry values can be set by reg.exe (via cmd.exe) or with built-in mechanisms in PowerShell (Set-Location, Set-ItemProperty).
