What the Windows Security Button Does and How to Use It

What The Windows Security Button Does And How To Use It Featured Image

The Windows Security button is a physical button on some Windows tablets that lets you enter the login menu screen without a keyboard. It functions the same as if you pressed Ctrl + Alt + Del on a desktop or laptop. If the button is available on your tablet, it should be enabled by default.

Note: Windows Security is also the system default antivirus app for Windows 10 and 11. Let us show you which settings to enable within Windows Security to secure your PC.

What’s the Purpose of the Windows Security Button

The easiest way to understand the Windows Security button is to think of it like the unlock button on your smartphone. It’s a physical button that, when pressed, brings you to the login screen. On a smartphone, it would take you to your lock screen to enter your password.

The button offers an extra layer of security on tablets that aren’t built with an external keyboard. The secure attention sequence (SAS) requires you to enter a username/password, just as you would when logging in to a desktop PC.

Since desktops and laptops are built to work with a physical keyboard, the sign-in process is straightforward. On tablets, the on-screen keyboard doesn’t load before the sign-on screen.

The solution is the Windows Security button, which initiates the security process and provides the keyboard for you to enter a username/password. Essentially, it gives you the same level of security as a standard PC. Press this physical key at any time to lock your tablet and go back to the login screen.

FYI: check these privacy settings you should know about in Windows.

Use the Windows Security Button on Tablets

Before proceeding, please be aware that not all Windows tablets have a Windows Security button. For some tablets, it’s a button combination versus a single dedicated button. If you have trouble finding the button, please consult your tablet’s user manual for more details.

For most Windows tablets with a Windows Security button, it’s already enabled. You should see a screen during the boot process that asks you to press Ctrl + Alt + Del or the Windows Security button to log in. The screen may only display the button as the login option, depending on the device.

The physical button usually looks like a small window, a lock, or a key. It may be located along the sides or back of your device.

For example, in the image below, the Windows Security button on this HP Compaq tablet is just a small key that you press with a pen or paperclip. On other devices, it can look similar to the Windows key on your keyboard.

In some cases, your tablet may require you to press the Windows Security button + the Power key or Volume +/- keys. It really does vary greatly between manufacturers.

Enable/Disable the Security Button on Tablets

If the button doesn’t work, or you want to disable it, you can do this via your tablet’s settings. Please note that the steps below will vary based on the device. For instance, our Windows tablet doesn’t have a setting to disable the button.

Tap Start -> Settings -> Control Panel.

Go to Mobile PC -> Tablet PC Setting. For some tablets, you may need to go directly to Tablet PC Setting.

Accessing "Tablet PC Settings" in Control Panel on tablet.

Open Buttons -> Button Settings For, then tap Windows Security and select Change.

Finally, select Nothing in the Press list to disable the button. Tap OK to save your settings. If you want to enable the button again, switch to Log On.

Use the Windows Security Button on a Desktop

Laptops and desktops do not have physical Windows security buttons. Instead, you press Ctrl + Alt + Del to access the login menu screen. Depending on the device, you may also have to use this keyboard combo when your PC boots to enter the login screen.

If you prefer the key combo to lock your screen and take you directly to the login window, there are several ways to do this. You can also follow the directions below to disable this if you want.

Enable/Disable the Windows Security Button on Desktops

For desktops and laptops, it’s a little more complex than just toggling the physical Windows security button on/off. If you’re on a network computer, you may not have access to change anything about the user login process. For personal PCs, you should have permission, as long as you’re using an administrator account.

Registry Editor

Press Win + R, enter regedit.exe, and press OK. Navigate to the following path:

Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System
Navigating to location in Registry Editor.

Right-click DisableCAD, and select Modify. If you don’t see this option, you’ll need to use another method to enable/disable Ctrl + Alt + Del.

Selecting "Modify" from context menu in Registry Editor.

Change the Value data to 0 to enable the security key combo, or change it to 1 to disable it.

Changing value data for key in Registry Editor.

Press OK to save your changes, and exit the Registry Editor. Restart your PC for the changes to take effect.

Group Policy Editor

If you are running Windows Home Edition, you may need to enable the local Group Policy Editor before proceeding with this method. If you get an error when trying to open the editor, enable it and try again. If it still doesn’t work, you may not have administrative rights on your account.

Press Win + R and enter gpedit.msc. Press OK to open the Group Policy Editor.

Typing command in Run window.

Expand Windows Settings -> Security Settings -> Local Policies.

Navigating to Local Policies in Group Policy Editor.

Select Security Options. Scroll down in the right pane and double-click Interactive logon: Do not require CTRL+ALT+DEL.

Clicking "Interactive logon: Do not require CTRL+ALT+DEL" policy in Group Policy Editor.

Select Disabled to enable the key combo. Select Enabled or leave the setting as Not Defined to disable it. Click Apply to save your settings.

Setting policy to "Enabled" in Group Policy Editor.

netplwiz

A final method is to use the netplwiz command, which allows you to edit the user accounts to enable or disable the Ctrl + Alt + Del Windows Security function.

Press Win + R and enter netplwiz. Click OK to open the User Account window.

Select the Advanced tab. Check the Require users to press Ctrl+Alt+Delete box to enable the Security function. Or, uncheck it to disable it. If the box is greyed out, you don’t have permission to change this.
