How to Add or Remove the Sign-In Screen Power Button in Windows 11

This guide explains how to show or hide the Windows 11 power button on your sign-in screen. By default, Windows lets you shut down your computer before you even log in. This button allows you to access sign-in screen, sleep, hibernate, or shut down options quickly.

Why do this? You might want to hide the power button to prevent unauthorized people from turning off your computer while it is locked.

What happens when done? The power icon will either appear or disappear from the bottom-right corner of your login screen.

Method 1: Local Security Policy (Requires Admin Privileges)

You can use the Local Security Policy tool to change this setting easily.

1. Open the Start menu, type secpol.msc, and press Enter.

2. In the window that opens, click on Local Policies on the left, then select Security Options.
3. On the right side, find and double-click the policy named: Shutdown: Allow the system to be shut down without having to log on.

4. Choose Enabled to show the power button, or Disabled to hide it.

Click OK to save your changes.

Method 2: Windows Registry (Requires Admin Privileges)

If you prefer using the Windows registry editor, you can edit the registry settings. First, open the Windows Registry by searching for it in the Start menu.

1. Navigate to this path: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System
2. If you do not see the System folder, right-click the Policies folder, select New, then Key, and name it System.

3. Right-click in the empty space on the right side, select New, then DWORD (32-bit) Value.
4. Name this new value shutdownwithoutlogon.
5. Double-click shutdownwithoutlogon and change the Value data to 1 to show the button, or 0 to hide it.

Restart your computer to see the changes. You will see the power button appear or disappear as shown below:

Customizing the Start Menu Power Button

You can choose which options appear in your Start menu power list. Why do this? To keep your menu clean or add Hibernate for faster wake times. What happens when done? Your Start menu power icon will show your preferred options like Sleep, Hibernate, or Shut down.

1. Open Control Panel and go to Hardware and Sound > Power Options.
2. Click Choose what the power buttons do.
3. Click Change settings that are currently unavailable (Requires Admin Privileges).
4. Check the boxes for the options you want to see in the menu.

Changing Physical Power Button Behavior

You can decide what happens when you press the physical button on your PC. Why do this? To prevent accidental shutdowns. What happens when done? Your PC will perform the action you selected, such as Sleep or Do nothing.

In the same Power Options menu, use the dropdowns next to When I press the power button to select your preferred action for both battery and plugged-in states.

Troubleshooting Power Button Issues

If your power button is missing from the Start menu, it is often due to a corrupted power plan or a disabled policy. Try running the Power Troubleshooter in Settings > System > Troubleshoot > Other troubleshooters. If that fails, check your Fast Startup settings in the Control Panel as it can sometimes conflict with power states.

Summary

Managing your Windows 11 power button settings allows you to customize your sign-in screen security and Start menu convenience. Whether using the Local Security Policy, Registry Editor, or Control Panel, these steps help you take full control of your PC’s power management. Always ensure you have administrative rights before modifying system policies or registry keys.
