Changing the Logon Screen of Windows 7

By tweaking the Windows Registry, you can change the logon screen.

To Open Registry: Press windows +r & type regedit & press enter.


  1. Open the Registry Editor.

  2. In left pane of Registry Editor, go to HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\Authentication\LogonUI\Background

  3. Double-click the OEMBackground DWORD key and Set value of the key to 1.

  4. Select a background image for logon screen with size less than 256 KB and rename that image as BackgroundDefault.

  5. Copy that image, Open My Computer and go to C:\Windows\system32\oobe\info\backgrounds folder

  6. Paste it and select Copy and Replace. Tips: Cut and paste the original log-on Screen image in a folder for further use.

  7. Reboot, and now your logon image would have changed.

Note: Modifying the registry can cause serious problems that may require you to reinstall your operating system. I cannot guarantee that problems resulting from modifications to the registry can be solved.
