I'am not able to change my desktop background to any picture or windows 7's default aero themes.In brief, whenever I try to change themes from personalization option, icon type, top & bottom panes all sounds do take effect of new theme but the desktop background remains the same black solid color. Moreover, I can choose different solid colors e.g. white, blue, green etc, as my desktop background but unable to select any pictures or wallpapers instead. Could anyone please suggest me a solution to this problem?

Once you have changed your theme you need to SAVE it.

I always save the changes, mate but it doesn't work. I guess it's more serious than that.

No, it's my personal laptop and used solely my me. Does this have anything to do with Microsoft predefined policies? If so than what could I do to make it work?
