Lock Screen Customizer for Windows 8.1 and Windows 8

Lock Screen Customizer is a new software by Winaero. It allows you to tweak and extend
the options of the Lock Screen in Windows 8. It has nice UI with live preview of the changes you made:

Windows 8.1 users, a new version for you is ready. Check it out below!

It allows you to change the following options of the Lock Screen:
in Windows 8
  • background image;
  • date language;
  • time format (12/24 hours)
  • color set for sign in screen;
  • add Lock Screen Slideshow with autochanging background images every time you sign in.
  • enable verbose logon messages (see video below);
  • disable Lock Screen.

in Windows 8.1
  • the background image of the default Lock Screen;
  • the background color of the default Lock Screen;
  • date language;
  • time format (12/24 hours)
  • enable verbose logon messages (see video below);
  • disable Lock Screen.

Overview of the Windows 8 version:

While some of those settings like background image or color set are available via the Modern Control panel of Windows 8, others are inaccessible and have no user interface.
Lock Screen Customizer tries to fix this and provide to you options to take the full control of your Lock Screen.

For example, you can change the background image of the Lock Screen. However, when you sign out, you will see not your image but that green Seattle picture. This is the "default" Lock Screen, which has no customization options!

With help of Lock Screen Customizer you will be able to apply all your preferences to that default Lock Screen.

Lock Screen Slideshow
Lock Screen Customizer has a nice feature that I called as "Lock Screen Slideshow". If enabled, it will change Lock Screen background image every time you sign in. So every time you logged in you will get the new image at Lock Screen.

You can also enable this feature for the default Lock Screen, so it's background will be also changed with image of your Lock Screen.

Overview of the Windows 8.1 version:

Lock Screen Customizer for Windows 8.1, along with date and time formats tweaking, allows you to change the sign in color and the background image of the default Lock Screen. Please note that you don't need 3rd party lock screen slideshow anymore, Windows 8.1 provides the native one.

  • Windows 8 x64
  • Windows 8.1 x86
  • Windows 8.1 x64.
It is portable, freeware and supports multi-language UI.

    3. Right click on the Lock Screen Image in PC Settings and choose "Reset"
    4. Run the Lock Screen Customizer app.
    This should help.

    This program doesn't work on Windows 8.1. I can't change default Color Scheme and default Lock Screen image. It gives me an error.

    Maybe beacuse it was not designed for Windows 8.1 and was not updated yet?
    Don't you think this way, uh?

    Seems that a reboot is required to change the default lock screen on Win 8.1 Enterprise with an AD. Just spent an hour changing and changing...without rebooting and without any visible effects. ^^

    I was wondering what exactly this is doing to my computer. What is it changing and where is it changing it? Is it dangerous to the stability of the OS? I looked up a way to do it without a program and it required taking ownership of system files, does your program do that?

    This tool works great for getting the default lock screen in Windows 8.1, but it's doesn't seem to set the "accent" color. Please see the below registry file contents for how I set my default lock screen back (in addition to running WinAero Lock Screen Customizer). Change the DWORD hex value to the color you'd like (see the Microsoft chart for allowed colors).

    Windows Registry Editor Version 5.00

    Is there a way to use this app in command line. I want to change the lock screen in a Windows 8.1 Deployment.

    In order to resolve the "Failed to retrieve user SID" error, run the Lock Screen Customizer as a local user (not a domain user). You can either log in as the local user, open a Command Prompt as the local user, or just run the app in the context of a local user.

    Doesn‘t work, says “Failed to retrive current user SID”. Tried with non-Microsoft account too.

    Can you please figure out a way to disable the Network icon picture in the bottom left from the lock screen? (The one I'm referring to, for example, is the icon in your first video (4:43 minutes long) @ 3:13 (pink flower) & 3:20 (green leaf), etc.

    If you figured out a way, can you please update me at: pepanee@hotmail.com

    Thanks so much!

    How do I use the program to disable the lock screen so that the lock screen never shows? I ticked the option to disable the lock screen. Now what do I do. Do I just close the program? I did that and the lock screen still shows. I have Windows 8.1 64-bit.

    Looks like another great tool by Winaero, but when I click on "Change background image", the application nearly always crashes - but after starting the x86 version and getting the error message (wrong version) and restarting the x64 version it worked!


    PS: The app icon has white pixel borders instead of transparency.
