Speed up Defraggler in Defraggler Suggestions Posted April 1 · Report reply Or to try to answer Don's original post, dump Defraggler. If you're on Win 8 or 10 (and have sys restore enabled, and have more than 10% fragmentation) then you'll get the Windows defrag described above.

What was the fragmented percentage?
