How to change desktop background if "setting is disabled by an administrator"?

Question

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.

Solution

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.

It's critical to the functioning of the office that all screen backgrounds be identical. You wouldn't want to degrade the performance of the whole organization by changing your screen background, would you? :-)
