How to Defragment a Hard Drive on a Windows Vista PC

By Dan Gookin

Defragmenting is commonly called defragging. No matter what you call it, defragging or defragmenting your hard drive will speed up disk performance. If you haven’t defragmented your PC’s hard drive in a while (or ever), you’re in for a treat. A freshly defragmented hard drive makes your computer seem brand new.

Your PC’s main hard drive can be set to automatically defragment on a regular schedule when you use Windows Vista. Even so, you can manually defragment your hard drive or removable storage media.

To manually defrag the hard drive, or any storage media, in Windows Vista, follow these steps:

  1. Open the Computer window.

  2. Right-click the media you want to defragment, such as the main hard drive, C.

  3. In the drive’s Properties dialog box, click the Tools tab.
