I have a new laptop. it's sony vaio.. it's windows but i don't know what version...
I was wondering how could i change my desktop background? It's not like any normal laptop.. i know u can right click and click properties. but when i right click, there is no properties or so. And i tried searching how to change my desktop wallpaper in google but there's one answer, that says go to start then control panel, then go to appearance and click display . but when i click display, there's nothing that can change my wallpaper ... and i tried going to my documents and right click the photo to find some thing like "make this a desktop picture" but there's nothing like that...


So can anyone please help me please...Anyone who can help me gets 10 points
