Custom Log-on Screen Background on Win-7

How to Set a Custom Log-on Screen Background on Win-7

Step 1: Click start menu and type regedit in search box.

Step2: Navigate to 

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Authentication\LogonUI\Background

 

Step 3: Double-click the OEMBackground value and set its- value to 1.

 

   

If you doesnt found OEMBackground right click in the right pane and point to new submenu and select create new DWORD(32-bit)Value and name it as OEMBackground.

Note that selecting a new theme in the Appearance and Personalization window will “unset” this registry value. Selecting a theme will change the value of the key to the value stored in the theme’s .ini file, which is probably 0 – if you change your theme, you’ll have to perform this registry tweak again.

Step 4: In search box type gpedit.msc( group policy editor )

Navigate to

Computer Configuration\Administrative Templates\System\Logon

You’ll find a setting named “Always use custom login background.” Double-click it and set it to Enabled.

 

Step 5: Setting required image 

Note: your image file should be less than 256KB in size. 

Open this directory 

C:\Windows\System32\oobe\info\backgrounds

By default, the info and backgrounds folders don’t exist. Navigate to the C:\Windows\System32\oobe folder and create them yourself by right-clicking inside the folder, pointing to New, and selecting New Folder.

Copy your desired background image to the backgrounds folder and name it backgroundDefault.jpg.

The change will take effect immediately – no need to  reboot your system. Now you have to  log out or lock your screen (WinKey-L keyboard shortcut), you’ll see your new background.
