No, that's not a bug. There is no fix planned. For those that must have every file defragmented they need to find other solutions.

After I downloaded and installed Windows Live Messenger the defrag process wouldn't defrag all the files. I reformatted my computer without WLM and defragging was not a problem, worked like a charm. So, I downloaded and installed WLM again, and lo and behold the same problem occurred, the defrag program would not defrag all the files. I uninstalled WLM and defrag process still wouldn't defrag all the files. How do I solve this problem of not being able to defrag all of my files without reformatting my computer.
