We all love to customize or OS like changing its Boot screen, Logon Screen, themes, icons and so on. In past we had shared lots of tricks which allows you to change your Windows 7 Logon screen like 7LogonChanger.

But recently I am trying to change my Windows 7 logon screen but was unable, I tried all possible ways like registry trick, used different software’s but nothing worked.

Then think to closely take a look at my registry and luckily found the error, actually if you had installed TuneUp Utilities on your computer and used it to change your logon screen then it will secretly install a registry key which will disable all other program to change your Logon Screen.

Solution :-

  • Open your registry entry by typing regedit on your run command,
  • Now navigate to :-


  • Now on the right side pane by default you should see only one key, OEMBackground, but in our case you will find another key too, OEMBackgroundDisabledByTuneUpStyler,


  • To solve our problem you can either delete key or just disable the function of key, to disable its function double click on it and change its value from 1 to 0
  • That’s it, now you can change your logon screen using any trick.
