What does the Windows Security button do? how does it use?

The Windows Security button is a physical button on some Windows tablets that lets you get to the sign-in menu screen without the keyboard. It works the same as when you press Ctrl + Alt + Del on a desktop or laptop. If this button is available on your tablet, it will be enabled by default.

What is 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 takes you to the login screen. On smartphones, it will take you to the lock screen to enter your password.

This button provides an additional layer of security on tablets not equipped with an external keyboard. Secure Attention Sequence (SAS) requires you to enter a username/password, just like when you log in to the desktop.

Because desktops and laptops are designed to work with physical keyboards, the sign-in process is simple. On tablets, the virtual keyboard does not load before the login screen.

The solution is the Windows Security button, which starts the security process and provides a keyboard for you to enter your username/password. It essentially gives you the same level of security as a standard PC. Press this physical key at any time to lock your tablet and return to the sign-in screen.

Use the Windows Security button on your tablet

Before continuing, please note that not all Windows tablets have a Windows Security button. For some tablets, it's a button combination instead of a single dedicated button. If you have trouble finding the button, refer to your tablet's user guide for more details.

For most Windows tablets with a Windows Security button, this button is already enabled. You will see a screen during startup asking you to press Ctrl + Alt + Del or the Windows Security button to log in. The screen may only show this button as a sign-in option, depending on the device.

The physical button usually looks like a small window, lock, or key. It can 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 may look like the Windows key on your keyboard.
