Configure Disk Defragmenter Schedule in Windows Vista
Windows Vista automatically configures Disk Defrag to schedule defragment to run once a week, usually at 1am on Wednesday. I don't know about you, but I'm usually awake at 1am on wednesday, and I'd rather schedule it for a different time.
To open up the defragment utility, just type defrag into the Start menu search box, and hit enter. Click through the obnoxious UAC prompt, and you should see this screen:
From this screen, you can disable automatic defrag by unchecking the box. You can also modify the schedule by clicking the Modify schedule button (no surprise there)
Much better.. Not like I'm ever awake at 8am.


You might as well power down your computer when you sleep ? (Unless you're downloading or something)… What's the use of a computer that powered on when you don't even need it…
does it still defragment your pc if you've shut it down?
No, if you have the computer off it will not defragment.
Ok here is the situation. In my program logic & design class my home work asn 9 was to perform disk defragmentation on my disk drive. Explain the steps to perform the process. Note thefile system an operating system of my computer. provide and account status of my drive after the process. Then click view report button, press save as. open the file I save and copy and past its contents into my report document that I will be turning in. PROBLEM, VISTA never gave me that option it just stopped when the defragmentation process was over it went back to the box above. So now what do I do to get the results that I need???? HELP!!!!!!!!!
Can I schedule my computer to do disk defrag when my computer has been shut down. For example what if I wanted to schedule disk defrag for 12:00 am every Sunday. I know I'm not up at that time and my computer has been shut down
I run defrag on a schedule on my laptop. The computer is on, but in the "Switch User" status, and the cover is closed. The defrag has been running at 1 AM on Wednesday each week in this mode. If the computer is completly shut down, it will not run.
OK .. defrag is now dumbed down .. no estimate of time, no progress to date.
Q. how can I chosse what drive to defrag ?
Q. How can I tell if it's defragging all drives and not just sys drive
It doesn't work this way any more. With the install of SP1, it'll still try to do an analysis on a USB disk, even if this box is unchecked.
Nice, Microsoft. Happy to have that lovely addition– NOT!!
I finally made the leap to Vista and I must say the disk defragmenter application is really dumb down; just as others stated! In the past I've used disk keeper, which was okay until I found Perfect Disk. If those of you that want a better application I would suggest Perfect Disk. Do what I do and download the trial and run it for 30 days and then uninstall it.
