As I was at a friend’s place a while ago, she asked me:
“Can you take a look at my new laptop? I want to set this picture as my wallpaper, but I can’t find how to do that…”
I was like: “What? That’s supposed to be easy!”
So, I had a look had her laptop and turns out, that when running WIndows 7 starter edition, you are simply not able to change your wallpaper. WTF?!?! Luckily there are a few apps floating around that allow you to change your wallpaper after all.
