Using Disk Cleanup; Updating Programs And Drivers; Cleaning Your Computer - HP Notebook User Manual

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 disk.
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 disk, and then select Uninstall apps to free up disk space.
2. Follow the on-screen instructions.

Updating programs and drivers

HP recommends that you update your programs and drivers on a regular basis to the latest versions.
Updates can resolve issues and bring new features and options to your computer. Technology is
always changing, and updating programs and drivers allows your computer to run the latest
technology available. For example, older graphics components might not work well with the most
recent gaming software. Without the latest driver, you would not be getting the most out of your
equipment.
