How to Change Your Lock Screen Background Image in Windows 8 and Windows 8.1

In Windows 8 and 8.1 there are two "Lock" screens.
This tutorial will show you how to change the lock screen background image for your user account to be any image you would like when you lock the PC while signed in to Windows 8 and Windows 8.1.
If you are using a Microsoft account and have the Personalize setting turned on to sync, then the lock screen background you currently have set will also be displayed on any PC that you sign in to with the same Microsoft account.
- The user lock screen is the one that displays when a user locks the PC while still signed in to Windows, and when the user is selected on the sign in screen, times out, and returns to the lock screen. Each user is able to change their lock screen background image to an image of their choice.
- The default Lock screen image is the one that displays when there are no users currently signed in to Windows or selected on the sign in screen.
This tutorial will show you how to change the lock screen background image for your user account to be any image you would like when you lock the PC while signed in to Windows 8 and Windows 8.1.
If you are using a Microsoft account and have the Personalize setting turned on to sync, then the lock screen background you currently have set will also be displayed on any PC that you sign in to with the same Microsoft account.

The default background images used for the lock screen are located in the Screen folder below. If you delete any of the default image in the Screen folder below, you will no longer see recent background images under the current lock screen image.
C:\Windows\Web\Screen
C:\Windows\Web\Screen

When you use choose to use a custom image for your lock screen instead of one of the default images, Windows will save this image in the hidden system LockScreen_(letter) folder location below to open it from. This way if you should lose your original image, you could get a copy of it from here.
Here's how to be able to open it and view the image if needed:
NOTE: You must be signed in as an administrator to be able to do this.
1. You will need to take ownership (option four at link) of the hidden SystemData folder with "Administrators" or your user account, and check the Replace owner of subcontainers and objects box.
2. Open the SystemData folder, and open the S-1-5-21-.....(long number) folder for the user account that set this custom lock screen image. Each user account on the PC that uses a custom lock screen image will have it's own S-1-5-21-.....(long number) folder, so you may need to go in each one to find yours.
3. Open the ReadOnly folder, then open and look in each LockScreen_(letter) folder for the custom image. Each time you choose a custom image, a new LockScreen_(letter) folder is created in alphabetical order for each image.
Code:
C:\ProgramData\Microsoft\Windows\[B]SystemData[/B]\[COLOR=#ff0000][B]S-1-5-21...[/B][/COLOR]\ReadOnly\[B]LockScreen_[COLOR=#ff0000](letter)[/COLOR][/B]
