Since I can remember, my Windows 7 always shows 6 icons for fictitious Removable Disks. They aren't a problem, really - when I insert a real USB stick, it shows as yet another icon (but working).
But they are a mystery, and I've always wondered where they come from, why are there 6 Removable Disk icons for disks that don't really exist. If I try to open any of them, I only get this dialog saying:
Please insert a disk into Removable Disk K:
So where do these icons come from? I most definitely don't have 6 USBs attached to my computer, or anything like that.

is great for something like that even allows you to link to all the information after you have copied the relevant details into the question.
