Disk Defragmenter in Windows Vista

Unlike previous versions of Windows, Disk Defragmenter ("Defrag") runs silently and automatically in Windows Vista. By default, Windows Vista will defragment your harddrive automatically at preset times (usually each Wednesday morning.) If your computer is not turned on when Defrag is scheduled to run, Vista will start defragmentation the next time the computer is started.

To disable or change the settings for Disk Defragmenter in Windows Vista:

1) Click START, then CONTROL PANEL. In the CONTROL PANEL click the SYSTEM AND MAINTENANCE option.

2) In the System and Maintenance window, click the PERFORMANCE INFORMATION AND TOOLS option, then click the ADVANCED TOOLS option.

3) In the Advanced Tools window, click on OPEN DISK DEFRAGMENTER. The following window will open:

4) You can then choose to disable the "Run on a schedule" option, you can modify the automatic run schedule, or you can choose to run Defragment immediately.

Disk Defragmenter is an effective way of maintaining your computer's speed and performance. Scheduling Defrag to run automatically in the background is recommended, as it takes only a small amount of your computer's resources, and eliminates the need to manually run the program.
