How to find the shutdown button on the Win10 lock screen login interface?

The root of the problem is that the Win10 Group Policy settings vary from user to user. Mention "Group Policy", users who are familiar with Win10 should know that this is a feature that is only available on Win10 Professional. So if you are a Win10 Home Edition user, then I am sorry that there is no other solution for this, and I will give you a specific method after finding the registry key of this project in the future.
For Win10 Professional users, you can add or remove the login interface power button in the following ways:
1, after entering "> group policy" in the Cortana search bar, click the first "best match" Result (or enter gpedit.msc after running and press Enter).

2. In the left directory, find the computer configuration → Windows Settings & Rarr; Security Settings & Rarr; Local Policies & Rarr; Security Options, then find in the right project "Shutdown: Allow the system to be logged in." Close down & rdquo;.

3. Double-click to open the project, and then select “Enabled” you can see the power button icon in the lower right corner of the login interface, select “disabled” will cancel the icon display.

4. After selecting it, click OK, then perform the lock screen operation (press Win+L), you can see the modified result, as shown below (to select “ Enabled) ).

Through the above steps, we can find the disappeared shutdown button on the Win10 lock screen login interface.
