    Following your instructions above I cannot see the RUN AUTOMATICALLY box.

    I have Windows Vista and I followed the above steps and do not see a selection for run automaticaly. I see run on a schedule. Is that what you mean by automatically? I am looking for something to defrag constantly/

    I did that a year ago to have automatic defrag of my hard drive.
    Yesterday I downloaded defraggler to check that it was doing the work properly and I have more than 40% fragmented files for a total of 90.4 Gb !!!

    I usd to rely on windows tool to defrag the hard drive, but I think this one has failed completely that even a free solution is way better than this one (I am now down to 4% fragmentation with the free tool …)

    I can only recommend turning off auto defrag, as it runs way too often (for me almost daily) – And consequently reducing performance while it runs (2-3hours for me), while also reducing harddrive life time.
    However, you need to remember to run defrag yourself, as defragmenting is important for performace – My rule of thumb is once a month.
