In an effort to make things easier, some things like a DLNA server can pop up in such an area. This is not a bug.
Your post makes me think you might be thinking it's time for the makers and retailers to offer more documentation. Do you feel like every question you ask is being googled?

Today I saw that suddenly there is this strange device in my "devices and printer" window. It has an icon that looks like a tablet (but my computer is a "normal" laptop) and although the manufacturer (Acer) is correct and the name does correspond to my computer's name in the network, it gives a "model" which doesn't have anything to do with my computer: "Iconia W511"... which would indeed be something like a tablet as the icon shows.
Along this strange device I also see my bluetooth mouse and my smartphone, both are displayed correctly, without any strange properties.
I didn't have any problems so far, but it's just not normal that this computer appears within "devices and printers" so I'd like to get rid of that before problems come up.
Note: Earlier today I had a complete "freeze" of my computer (not even Ctrl+Alt+Del worked) so I shut it down by pressing a couple of seconds on the power button. It is after this that I went into the "devices and printers" control panel and saw the strange device, but maybe it was there before.
Has anyone got any idea why this happened and how I can fix it?
