How do I 'defrag' my computer?

Start-All Programs-Accessories-System Tools- Disk Defragmenter.

You should do a disk cleanup before defragmenting though. It's better for the system. To get to the disk clean up follow the steps above and choose disk clean up instead of disk defragmenter.

For Windows XP

Begin by first clicking on the Start Button.

Then move your mouse over the All Programs icon to display all Start Menu folders.

If your Start Menu is set to the Classic View, move your mouse over the Programs folder instead.

Now, move your mouse onto the Accessories menu folder until it expands.

Then move your mouse onto the System Tools menu folder until it expands.

Now Click on the Disk Defragmenter icon to launch the program.

Then use your mouse to highlight the drive that you want to Defragment?

Then click on the Defragment button located on the lower left hand center of the screen.

Windows XP will analyze your drive first and then display a visual estimate of the final results.

And Windows XP will continually show you a progress indicator bar depicting its progress.

When Windows is finished it will ask you if you would like to quit the Defrag Program.

Select YES to quit the Disk Defragmenter Program and then reboot your computer.

Go to My Computer..Right click the drive you want to defrag

Select properties

A window will popup, Goto the tools tab.

Click the defrag now button.

The defrag program will then come up...hit the defragment button

Before defragmenting, though (since it's already been answered), it's always a good idea to press "ctrl+alt+delete," click "processes," and close as many things as possible so your computer won't be as busy. When you go to C drive, click "check now" to make sure everything on your comp is running well.

Start>All programs>Accesories>System Tools>Disk Defragmenter.
