Delete old Lock Screen images in Windows 11/10

All Lock Screen background images you apply via Settings reside under a system folder at the following location –

C:\ProgramData\Microsoft\Windows\SystemData\<User_Account_Security_Identifier>\ReadOnly

Here User_Account_Security_Identifier is the number for your User Account. You will have to enable the Show Hidden Files option by opening File Explorer Options > ‘View’ tab and check the box against “Show hidden files, folders, and drives” option.

Also, you will notice that once you have access to the ProgramData folder, you cannot readily open SystemData folder since it is protected by Windows. If you try to, you’ll get the following prompt:

You don’t currently have permission to access this folder.

So it is essential that you first take Ownership of the folder manually. When done, you will be granted access to the ‘SystemData’ folder.

Open the folder, and you will see some folders listed instantly.

Find the folder that contains your use account SID (Security Identifier) number in its name and open that folder.

[To find your SID number, open CMD and run the following command – whoami /user].

This will open another folder with the name ‘ReadOnly’. Open it, and you’ll see a few other folders.

The number of these folders may vary on different computers. However, each of these folders will contain the Lock Screen background images in original resolution with the name “LockScreen.jpg” alongside other information.

Open the folder containing the Lock Screen image which you want to delete permanently, and then empty that folder.

The Lock Screen image will disappear from the Lock Screen background history list in the Settings app.
