Windows – How to change desktop background if “setting is disabled by an administrator”?

desktop-customizationwindowswindows 7

I use Windows 7 in an office. Over the weekend, our corporate overlords replaced everyone's desktop backgrounds (holiday photos, landscapes, family portraits) with company colours–lurid bright green. How can I change it?

I tried 'Personalize' but the desktop background setting is locked.

One or more of the settings is disabled by an administrator.

Is there anyway I can bypass the restriction? I have local admin rights on the computer.

Solved. Located lurid green background at C:\Windows\banner.bmp. Renamed background of my choice in Pictures to banner.bmp, then copied it to C:\Windows. Restarted explorer.exe, now shows my background.
