    • What Time: Select a time from list.
    Tip   Tip
    Recommended Schedule of Times to Defrag
    NOTE: The more you save and delete items off your hard drive, the more often you should defrag. Adjust to your needs.

    Schedule Description
    Once a Month For a user that is only on the computer a few hours a week and does not do much file saving and deleting. You rarely install and uninstall programs.
    Once a Week For most average users that use the computer for a few hours on a daily basis and does a lot more file saving and deleting. You only do a few installing and uninstalling of programs.
    Once a Day For your power user that uses the computer for several hours a day and does an unbelievable amount of file saving and deleting. You do a lot of installing and uninstalling of programs.

    9. To Manually Run Disk Defragmenter Now
    A) Click on the Defragment now button. (See screenshot below step 3)

    OPTION TWO

    Set Defragmenter to Wake the Computer to Run

    NOTE: By default Disk Defragmenter will only run when the computer is running and during low or idle usage in the background unless you run it manually, and not when the computer is in sleep mode or turned off. This will show you how to set Disk Defragmenter to wake the computer from sleep mode to run. This way you can schedule it to run when you are not using the computer in Option One above.
    1. Open the Start Menu.
    A) In the white line (Start Search) area, type taskschd.msc and press Enter.

    B) Go to step 3.
    OR

    2. Open the Control Panel (Classic view).
    A) Click on the Administrative Tools Icon.

    B) Click on Task Scheduler.
    3. In the left pane, click on the arrow next to Task Scheduler Library, Microsoft, and Windows to expand the folders. (See screenshot below step 4)

    4. Click on the Defrag folder.

    5. In the middle pane right click on ScheduledDefrag and click on Properties. (See screenshot above)

    6. Click on the General tab. (See screenshot below step 7)

    7. Check the Run with highest privileges box.

    8. Click on the Conditions tab. (See screenshot below step 9)

    9. Check the Wake the computer to run this task box, and click on OK.

    That's it,

    Re: Disk Defragmenter

    Hi Brink. I just loaded Auslogics Disc Defrag (thanks by the way for the list of free loads) and I have read that some have had some trouble with Vista Defrag, is there some other way to disable Vista Defrag so that it doesn't cause problems later? Maybe you have a Tutorial that I havent found yet? As always no need for speed. Thanks a bunch! Later, Bare Foot Kid

    Hi Bare Foot Kid,

    Nope, you did not miss anything. Unchecking the Run on a schedule option will turn off the automatic running of Vista Defrag. It will then not run unless you manually run it, so it will not hurt anything to let it sit dorment. I just deleted the shortcut in the Start menu for it and replaced it with a shortcut for Auslogics instead.

    Re: Disk Defragmenter

    How odd. My defrag is set to auto. How did that happen? I know I didn't do it and it wasn't done the last time I defragged, just a couple of days ago. When I clicked on it, it started defragging instead of the usual, check volume thingie first.

    Hi Bubba,

    Did you have it set to run on a schedule? It may be still running on or finishing from the set scheduled time.

    Re: Disk Defragmenter

    In my experience (and as I have also read elsewhere), waking the computer to run defrag will not work if you set the computer to ask for a password upon waking up, correct? Do you know a way around this (without removing the password)?

    Also, I was wondering if defrag will continue its job even if your computer goes to sleep?

    Thanks for any help.

    Re: Disk Defragmenter

    Hi Hannaxbear, and welcome to Vista Forums.

    I have not tried it with Disk Defragmeneter, but if it will not wake the computer to run due to this, then removing the password is the only workaround that I know of. You might take a look at this to see how this works for you.

    Task Scheduler - Wake Up Computer


    If you manually have Disk Defragmenter running, I believe the computer will not go to sleep until it has finished.

    Re: Disk Defragmenter

    I unchecked auto schedule for disk defrag a while back. Looked at it again today and its re-enabled itself. Not sure why. I cleared the check box again, and installed disk keeper. Now Vista defrag does not show up in the tools menu. I can get to it with the command line dfrgui though. Where has the listing of it gone from tools?
