One of the many nice features in windows 7 is the Desktop Slideshow. You can choose more than one wallpaper and a duration to cycle wallpapers.

You can also change your wallpaper manually by right clicking on the desktop and clicking the Next Desktop Background command from the context menu.

The Bug

If you delete/rename the current wallpaper and then try changing the wallpaper manually by clicking on Next Desktop Background from the desktop context menu, the wallpaper doesn’t change.

If you are on windows 7 please try it and confirm whether this happens on your machine or not.

Update

I posted the same to windows7update.com and they accepted it as a bug.  Here is the link to the post http://www.windows7update.com/desktop-slideshow-bug.html.
