Registry errors in computers...What exactly causes these errors? Why do they occur so often? I've always had some kind of program running in my computer that delete these errors. I have PC Tools Registry Mechanic which apparently do find these errors and repairs 'em for me but, my question is not about the program, these do a fine job...my question is about these so-called registry errors. How come these occur so often? What exactly causes these errors?? It seems as though everyday I turn on my compuer there always seems to be a new list of registry errors to be cleaned out.
