How to Enable or Disable Ctrl+Alt+Del Secure Sign-in in Windows

Windows has had a longstanding security feature where administrators can require users to use Ctrl+Alt+Del at sign-in. This ensures that user credentials are entered in the trusted Windows logon screen instead of a fake or spoofed alternative. It’s a very useful tool for high-security enterprise environments.

However, in some setups, this may not be ideal. For kiosk, VDI, or single-user setups, it might be more convenient to disable this security feature to streamline the logon process. Whatever the case, it’s important for IT administrators to manage this setting and ensure that all their devices are aligned with their organization’s security policies and system requirements.

Ways to enable or disable secure sign-in in Windows

Individual users can manage this setting using netplwiz, a.k.a. the User Accounts window. For enterprise setups, you can use the Local Group Policy Editor, make edits to the Windows Registry, or deploy a PowerShell script.

📌 Prerequisites:

• Administrator privileges: Changing group policies or making edits to the Windows Registry will require administrator privileges. To check if you have the necessary permissions, go to Start Menu > Settings > Accounts. The word “Administrator” should be printed under your username.
• Password log-in prompt: This guide is not applicable if the user is using biometric or PIN-only login. It will only work if they are prompted to enter their password to log in.

📌 Recommended deployment strategies:

💡 Tip: General users can use netplwiz or the Legacy Control Panel to change the settings.

Method 1: Enable or disable via netplwiz (GUI)

📌 Use case: This method is ideal for individual users.

1. Press Win+R, type netplwiz, and press OK. This will open the User Accounts window.
2. Go to the Advanced tab.
3. Under the Secure sign-in section, check or uncheck the Require users to press Ctrl+Alt+Delete box, according to your needs.
4. Click Apply > OK.

Method 2: Enable or disable via Group Policy

📌 Use case: This method is ideal for enterprise setups and can be deployed using an endpoint management tool.

💡 Note: The Local Group Policy Editor is not available in Windows 10/11 Home. If that’s the version you’re using, you can make edits to the Windows Registry instead.

1. Press Win+R, type gpedit.msc, and press OK. This will open the User Accounts window.
2. Navigate to this address: Computer Configuration > Windows Settings > Security Settings > Local Policies > Security Options
3. Scroll down and locate the Interactive logon: Do not require CTRL+ALT+DEL policy.
4. Enable or disable the policy according to your needs. Enabling it means that users will no longer be required to press Ctrl+Alt+Del when signing in.
5. Click Apply > OK.
6. Restart the computer to apply the changes.

Method 3: Configure via Registry Editor

📌 Use case: This method is ideal for enterprise setups.

⚠️ Important: Remember to back up the Registry before proceeding to prevent unintended consequences.

1. Open the Start Menu and search for Registry Editor to open the program.
2. Navigate to this address: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System
3. Find the DisableCAD value. If it isn’t there, follow these steps to create it:
   • Right-click the System key > New > DWORD (32-bit) Value.
   • Name it DisableCAD.
4. Double-click DisableCAD.
5. Change the value according to your needs.
   • 0 – Users will be required to press Ctrl+Alt+Del when signing in.
   • 1 – Users will not be required to press Ctrl+Alt+Del when signing in.
6. Click OK.
7. Restart the computer to apply the changes.

Method 4: PowerShell Script for Automation

📌 This method can be used to deploy Windows Registry edits to all your managed devices in an enterprise setup using a remote PowerShell tool.

1. Open the Start Menu and search for Windows PowerShell to open the program.
2. To require users to press Ctrl+Alt+Del when signing in, type this command and press Enter:
   Set-ItemProperty -Path “HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System” `
   -Name “DisableCAD” -Value 0
3. To disable this feature and allow users to sign in without pressing Ctrl+Alt+Del, type this command and press Enter:
   Set-ItemProperty -Path “HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System” `
   -Name “DisableCAD” -Value 1
4. Restart the computer to apply the changes.

⚠️ Things to look out for

Additional considerations when managing Ctrl+Alt+Del sign-in

• The Group Policy Editor is not available in Windows 10/11 Home. If that’s the version you have, use the other methods instead.
• GPOs can override changes made through netplwiz and the Windows Registry.
• If users have biometric login enabled, they may not be prompted to press Ctrl+Alt+Del to sign in. This may only be effective using password login.
• These are system-wide changes, meaning they will apply to all device users.
• Enabling secure sign-in is recommended for multi-user devices or for sensitive and high-security environments.

Why enforce or disable secure sign-in?

Enabling secure sign-in can heighten device security by increasing protections against credential theft. Ctrl+Alt+Del will ensure that users will be signing in using the legitimate logon screen, and bad actors will have a harder time spoofing or tricking people to enter their username and password in fake logon screens.

However, this extra step may not be ideal for some users and environments. In kiosk, VDI, or single-user setups, it might be preferable to keep this feature disabled to streamline the logon process and make things easier for the end user.

Enhance security by enabling Ctrl+Alt+Del secure sign-in

Enabling or disabling the Ctrl+Alt+Del secure sign-in can help standardize logon procedures across your organization. It can be done using the Local Group Policy Editor or by making edits to the Windows Registry. Individual users can also manage this setting using netplwiz or the User Accounts Window.

This feature can help prevent spoofing and ensure that users are using the legitimate Windows logon screen when signing in instead of a fake or spoofed logon page. This feature can be critical in keeping your managed devices secure. However, in kiosk, VDI, or single-user setups, you may prefer to streamline the logon process instead to make things more convenient for the end user. Whatever the case, it’s important to assess your organization’s goals and requirements and apply what will work best for your current situation.
