Prevent users from changing the lock screen in Windows
In this article, I will tell you how to set a constant image for Lock Screen so that others cannot make changes to it.
NOTE: These settings only work on Windows 10/8 Enterprise, Windows 10/8 and Windows Server Editions. It does not work on Windows 8/10 Pro and Windows 8 RT editions.
Using the Registry Editor
1 Press Windows + R simultaneously and set regedit in the Run dialog box.
2 Navigate to the next registry key :
3 Create a string with the name LockScreenImage in the right area of this location if not present. Double-click it and enter the position of the required lock screen as value data (16).
4 That’s it! Close and restart the Registry Editor (16) to get results.
Using the Group Policy Editor
NOTE : This group policy option is only available in Windows 10/8 Pro and Windows 10/8 Enterprise Editions editions.
1 Press Windows + R combination and place gpedit.msc in the Run dialog box.
2 In the left pane, navigate to :
Computer Configuration -> Administrative Templates -> Control Panel -> Customization
3 Now look in the right pane to get the named policy Force a specific default lock screenshot as shown above.
4 Double-click this policy to open the window below.
5 You can now make the following settings :
Allow Lock Screen Background Change = Disable/not configured (default)
Disable Screen Lock Change Background = Enabled
If you select Enabled, specify the path of the unquoted image in the window box.
This setting allows you to force a default lock screen by entering the path (location) of the image file. This setting allows you to set the default lock screen that appears when no user is logged in and set the specified screen as the default screen for all users (it replaces the default inbox screen).
After the changes, click Apply followed by OK.
Here you can also see Prevent changing the lock screen setting . Activate it.
This setting prevents users from changing the displayed background image when the camera is locked. By default, the user can change the background image that appears when the device is locked. If you enable this option, the user cannot change his screen and sees the standard screen instead.
If Force uses a specific default lock screen in conjunction with the setting Prevent the lock screen image from being changed, you can always force the specified lock screen image to be displayed.
