Using Disk Defragmenter

As you use your computer over time, the files on the hard drive become fragmented. A fragmented drive means data on your drive is not contiguous (sequential) and, because of this, the hard drive works harder to locate files, thus slowing down the computer. Disk Defragmenter consolidates (or physically reorganizes) the fragmented files and folders on the hard drive so that the system can run more efficiently.

NOTE: It is not necessary to run Disk Defragmenter on solid-state drives.

After you start Disk Defragmenter, it works without supervision. However, depending on the size of your hard drive and the number of fragmented files, 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.From the Start screen, type d, and then type disk in the search box. Select Settings, and then select Defragment and optimize your drives.

3.Follow the on-screen instructions.

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 run more efficiently.

To run Disk Cleanup:

1.From the Start screen, type d, and then type disk in the search box. Select Settings, and then select Free up disk space by deleting unnecessary files.

2.Follow the on-screen instructions.

Adding or replacing memory modules

Adding memory can help improve your computer's performance. Your computer is like your physical work area. The hard drive is the filing cabinet where you store your work and the memory is the desk where you work. When your memory isn’t big enough to hold all your work easily, like a desk
