Two ways of disabling Ctrl-Alt-Delete on logon

Especially in domain environments users are forced to press Ctrl-Alt-Delete (German: Strg-Alt-Enf) to logon any machine by default.

Some like this feature, I not.

I have found two ways to disable this on Windows 7® and Vista®.

Not Requiring Ctrl-ALT-DEL at logon
Vista requiring ctrl-alt-del before login

The two ways are:
  1. Advanced User Accounts Control Panel (NETPLWIZ; %systemroot%\system32\netplWiz.exe)
  2. Local Security Policy

The Advanced User Accounts Control Panel is reachable via
  • <Win> + <R> ⇒ type Netplwiz ⇒ hit <Enter>
  • Start button or <Win> ⇒ press Run ⇒ type Netplwiz ⇒ hit <Enter>
  • Start button or <Win> ⇒ press "Help and Support" ⇒ search for "Secure Login" or Ctrl-Alt-Del ⇒ usually the first result ⇒ hit "Click here to open Advanced User Accounts"
  • Control Panel ⇒ User Accounts ⇒ User Accounts ⇒ Manage User Accounts ⇒ Advanced
    [not reproduceable]
If Panel is open switch to Advanced Tab and under Secure Logon tick the checkbox right before Require Users to Press Ctrl-Alt-Delete.

The Local Security Policy is reachable via
  • Start or <Win> ⇒ Control Panel ⇒ System and Maintenance ⇒ Administrative Tools ⇒ Local Security Policy ⇒ Local Policies
  • <Win> + <R> ⇒ Type gpedit.msc ⇒hit <Enter> ⇒ Local Computer Policy ⇒ Computer Configuration ⇒ Windows Settings ⇒ Security Settings ⇒ Local Policies
Select Security Options and double click on Interactive logon: Do not require CTRL+ALT+DEL and select Enabled.

Have fun.
