All listed Defrag Apps such as JK, Smart..etc. are of No Good if the Activity of De-fragmentation in itself remains blocked from the end of an Administrator! Hence, I would urge you to please issue a Note or a Proactive Advisory in this regard to prevent a further harassment of the intended User. Secondly, can anyone explain that Why on Earth the "harm free" activity of De-fragmentation remain at the privilege of an Administrator's nod? Suggestions will be appreciated!
