It's not that strange, because I only recently (within the last month), deleted all of my shadow copies in order to best organize C: for defragging, and then made a new one. While checking for this thread, I saw that I had 19 ghosts collected, and only 1 valid shadow copy. It is not totally clear to me, but it seems that any time that files are altered on C: to any extent, the system makes a new shadow copy, some of which are just added to other valid shadow copies. What causes a shadow copy to become a ghost is unknown to me as supernatural ghosts.
EDIT: I know that Windows Updates often creates a new restore point, which I assume means a new shadow copy, as well as some programs when they are installed do the same. This accounts for multiple valid shadows, but again, I'm uncertain about the ghosts.
