What if you can you use a keyboard shortcut to switch to next desktop background wallpaper, yes it is possible via AutoHotKey script executable we have created for you. You just need to press Win+n keys to change the desktop background instantly with the new one.
I found this tip searching the internet: It can be found here – http://www.facebook.com/note.php?note_id=234974903408
Now instead of right clicking you desktop to change your wallpaper ,you can press your “Windows Key + N”.
Now go ahead and download the file, run it and try it for yourself. This is a cool little program that saves a lot of hassle just to change the background wallpaper in Windows 7. I like it I hope you will too.
