How to Enable CTRL+ALT+DEL for Windows 11 Sign-in

This guide shows you how to add extra security to your Windows 11 sign-in. You will learn how to make your computer require the CTRL+ALT+DEL keys before you sign in.

Requiring the CTRL+ALT+DEL command creates a ‘secure sign-in’ path. This ensures that the login screen you see is genuine. It prevents malicious software from showing you a fake login screen to steal your password. This is a standard security practice for businesses.

What happens when done?

Once you enable this, your computer will not show the password box immediately. You must press CTRL+ALT+DEL first. This confirms you are physically at the computer and ready to log in securely.

Method 1: Local Security Policy (For Pro, Enterprise, and Education editions)

Note: This step requires admin privileges.

1. Open the Start Menu and search for secpol.msc to open the Local Security Policy editor.

2. In the left menu, click on Local Policies and then select Security Options.

3. On the right side, find and double-click the setting named: Interactive logon: Do not require CTRL+ALT+DEL.

4. To enable the security check, select Disabled. To turn it off, select Enabled. Click OK when finished.

Method 2: Windows Registry (For Home edition)

Note: This step requires admin privileges.

Windows 11 Home does not include the Local Security Policy editor. You can use the registry instead.

1. Press the Windows key + R, type regedit, and hit Enter.

2. Navigate to this path in the address bar:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon

3. Look for a value on the right side named DisableCAD. If it is not there, right-click in an empty space, select New, choose DWORD (32-bit) Value, and name it DisableCAD.

4. Double-click DisableCAD and set the value to 0 to require the keys, or 1 to disable the requirement. Click OK.

Method 3: PowerShell Automation

Note: This step requires admin privileges.

IT administrators can use this script to enable secure sign-in across multiple machines:

Set-ItemProperty -Path 'HKLM:\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon' -Name 'DisableCAD' -Value 0

Summary

Enabling CTRL+ALT+DEL adds a ‘secure sign-in’ layer to your Windows 11 PC. While Pro users can use the Local Security Policy, Home users can modify the registry. This protects you from fake login screens and is a recommended security best practice.
