Improving hard drive performance
Using Disk Defragmenter
As you use the computer, files on the hard drive become fragmented. Disk Defragmenter
consolidates the fragmented files and folders on the hard drive so that the system can run more
efficiently.
To run Disk Defragmenter:
1. Select Start > All Programs > Accessories > System Tools > Disk Defragmenter.
2. Click Defragment now.
NOTE: Windows includes the User Account Control feature to improve the security of your
computer. You may be prompted for your permission or password for tasks such as installing
applications, running utilities, or changing Windows settings. Refer to Help and Support for more
information.
For additional information, access the Disk Defragmenter software Help.
Using Disk Cleanup
Disk Cleanup searches the hard drive for unnecessary files that you can safely delete to free up disk
space and help the computer to run more efficiently.
To run Disk Cleanup:
1. Select Start > All Programs > Accessories > System Tools > Disk Cleanup.
2. Follow the on-screen instructions.
