I am using Asus Notebook K60IJ Series and 64-bit Operating System with windows 7 as my operating system. First time when I got this I kept the wallpaper to some image under Scenes but I was bored of that so I just changed that wallpaper to some image under nature and the change was successful. But when I restart my system by shutting it down there was no change in wallpaper and I was able to see only the previous wallpaper. I have tried several things to resolve it as tried to save it as them but no help so I want to know what can be the problem with my system? So if anyone using Windows 7 please let me know the solution for this problem of mine.
