A short-cut icon has recently appeared on my desktop - a little green sphere with three smaller blue spheres orbiting it like planets. Says its a short-cut to Homegroup. I didn't consciously put it there - I don't want it - there's only me living here and I only use the one computer, but see no way of removing it as the usual 'right click - select delete' isn't on offer. So how do I get rid of it?
Windows 7, running as a 'User'.
