Im having the same problem, I have a TOSHIBA laptop satellite L355 S7915. I remember the good ol days when i could just simply choose a background. Now, its just black. I can change it or choose a different one, but the background continues to be black.

There is a chance your Win7 background to go black (without a possibility to add a background picture) if your Windows is not activated.
Did you have a non-genuine copy of Windows activated in some kind of non-Microsoft (illegitimate) way. If this was the case, and you recently effectuated Windows Update + restarted, your copy of Windows will go back to non-activated mode where the background is black with no possibility to change it.
Easy way out - register your copy ow Windows with a legitimate Windows key.
