User Guide - Windows 7

After you start Disk Defragmenter, it works without supervision. However, depending on the size of your hard
drive and the number of fragmented les, Disk Defragmenter may take more than an hour to complete.
HP recommends defragmenting your hard drive at least once a month. You may set Disk Defragmenter to run
on a monthly schedule, but you can defragment your computer manually at any time.
To run Disk Defragmenter:
1. Connect the computer to AC power.
2. Select Start > All Programs > Accessories > System Tools > Disk Defragmenter.
3. Click Defragment disk.
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 software, running
utilities, or changing Windows settings. Refer to Help and Support. To access Help and Support, select
Start > Help and Support.
For additional information, access the Disk Defragmenter software Help.
