Configure Disk Defragmenter Schedule in Windows 7 or Vista

Windows 7 or Vista automatically configures Disk Defrag to schedule defragment to run once a week, usually at 1 am on Wednesday, this is a default setting than can be altered to suit you.

It is advisable to do defrag at a time when the computer is not in use, if defrag takes place while the computer is in use it will take longer to complete its task & slow down the computer response as you use it.

To open up the defragment utility, just type defrag into the Start menu search box, and hit enter. Vista users will have to click through a UAC prompt, but you should see this screen:

Windows 7 users will see a very similar dialog, and will need to click the Configure Schedule button:

Defrag Windows 7

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):

Defrag Vista Modify Schedule

If you are on Vista and using at least Service Pack 1, you can also select which volumes will be automatically defragmented during this scheduled defrag. (Windows 7 users can select the volumes from the start screen).

Defrag Vista Select Volumes

I only have one drive in this computer, but you would see the list of all the drives here.
