Optimize your computer for peak performance
Our personal computers are like fine automobiles—they need preventive
maintenance to run efficiently and avoid major breakdowns.
The following tips can help improve your computer's performance. These
examples use Microsoft Windows XP. Some of the screens may differ from version
to version, but overall you'll find these tips work for all versions of
Windows, including Windows 95, Windows 98, Windows Millennium Edition (Me),
Windows NT, Windows 2000, and Windows XP.
By the way, in no way can you blow up your computer or files with any of
these procedures. These tasks use utilities provided within the Windows
operating systems to aid you in achieving the best system performance. This
article does not address tinkering with the registry files.

Whenever a program crashes, or you experience some power outage, your
computer may create errors on your computer's hard disk. Over time, the errors
can slow your computer. Luckily, the Windows operating system includes a Disk
Check program to check and clean any errors on your computer and keep it running
smooth.
To run Disk Check:
| 1. |
In your Start menu, click My Computer. |
| 2. |
In the My Computer dialog box, right-click on the drive you wish to
check for errors (for most of us this will be the C: drive, unless you have
multiple drives on your computer), and click Properties. |
| 3. |
In the Properties dialog box, click the Tools tab. In the
Error-Checking section, press the Check Now… button. A Check Disk
dialog box displays, as shown below.
Access Check Disk to check for errors on your
computer.
|
| 4. |
In the Check Disk dialog box, check all the check boxes. Click Start. |
| 5. |
You will see a message box that says you can schedule the disk check to
start the next time you restart your computer. Click Yes. The next
time you restart your computer, it will automatically run through a disk
check before displaying your login screen. After the disk check finishes,
Windows will automatically bring you to your login screen. Note Check
Disk can take more than an hour to check and clean errors on your computer. |

Your computer can pick up and store temporary files when you're looking at
Web pages and even when you're working on files in programs, such as Microsoft
Office Word. Over time, these files will slow your computer's performance. You
can use the Windows Disk Cleanup screen to rid your computer of these deadbeat
files.
To run Disk Cleanup:
| 1. |
In your Start menu, click My Computer. |
| 2. |
In the My Computer dialog box, right-click on the drive you wish to
check for errors (for most of us this will be the C: drive, unless you have
multiple drives on your computer), and click Properties. |
| 3. |
In the Properties dialog box, click Disk Cleanup.
Use Disk Cleanup to help clear unused files on
your computer.
|
| 4. |
Disk Cleanup will calculate how much space you can free up on your hard
drive. After its scan, the Disk Cleanup dialog box reports a list of files
you can remove from your computer, as pictured below. This scan can take a
while depending on how many files you have lying around on your computer.

| 5. |
After the scan is complete, in the Disk Cleanup dialog box, click
View Files to see what Disk Cleanup will throw out once you give it the
go ahead. You can check and uncheck boxes to define what you wish to keep or
discard. When you're ready, click OK. |
| 6. |
You can also select the More Options tab within the Disk Cleanup
screen to look for software programs you don't use much anymore. You then
have the choice to remove these unused programs. |

Don't be shocked, but your computer can get sloppy. Your computer often
breaks files side by side to increase the speed of access and retrieval.
However, as files are updated, your computer saves these updates on the largest
space available on the hard drive, often found far away from the other adjacent
sectors of the file.
The result: a fragmented file. Fragmented files cause slower performance.
This is because your computer must now search for all of the file's parts. In
other words, your computer knows where all the pieces are, but putting them back
together, and in the correct order when you need them, can slow your computer
down.
Windows includes a Disk Defragmenter program to piece all your files back
together again (if only Humpty-Dumpty had been so lucky) and make them quicker
to open.
To run the Disk Defragmenter:
| 1. |
In your Start menu, click My Computer. |
| 2. |
In the My Computer dialog box, right-click on the drive you wish to
check for errors (for most of us this will be the C: drive, unless you have
multiple drives on your computer), and click Properties. |
| 3. |
In the Properties dialog box, click the Tools tab, and then in
the Defragmentation section, click Defragment Now…. |
| 4. |
In the Disk Defragmenter dialog box, select the Volume (most likely your
Local Disk C:) at the top of the screen, and then click Analyze. |
| 5. |
After analyzing your computer, the Disk Defragmenter displays a message
stating whether you should defragment your computer. Press Defragment
to clean up your computer if necessary. The Disk Defragmenter will
reorganize files by placing together and organizing them by program and
size, as shown in Figure 5.

Defragmenter.

The World Wide Web is a sparkling achievement of modern society. It's
everywhere—from the home to the classroom. We use it to communicate, to work, to
play—even to waste time when there's nothing else to do.
Yet there's nothing more frustrating than having this technical marvel at our
fingertips 24 hours a day, 7 days a week, only to watch our computers access the
Internet at a crawling pace. Thankfully, Internet Explorer provides some useful
options for quicker Web surfing. Let's look at these options now.
Reduce the size of your Web page history
Internet Explorer stores visited Web pages to your computer, organizing them
within a page history by day. While it's useful to keep a couple days of Web
history within your computer, there's no need to store more than a week's worth.
Any more than that and you're collecting Web pages that will slow down your
computer's performance.
To reduce your Web page history:
| 1. |
In Internet Explorer, on the Tools menu, click Internet
Options. |
| 2. |
In the Internet Options dialog box, in the History section, find the
Days to keep pages in history: box. Type "1" in this box, as pictured in
the image below. Click OK.
Reduce the number of days to keep pages in
history.
|
Don't save encrypted Web pages
Encrypted Web pages ask for usernames and passwords. These pages scramble
information to prevent the reading of this sensitive information. You can define
Internet Explorer to not save these types of pages. You'll free up space by
saving fewer files to your computer, as well as keeping secure information off
your computer.
To not save encrypted Web pages:
| 1. |
In Internet Explorer, on the Tools menu, click Internet
Options. |
| 2. |
In the Internet Options dialog box, click the Advanced tab. |
| 3. |
In the Settings section, scroll down to the Security section. Check the
"Do not save encrypted pages to disk" option, as shown in the figure below.
Click OK.
Set up Internet Explorer so that you do not save
encrypted Web pages.

Microsoft works constantly to release updates to Windows and other Microsoft
products, including Office. At Microsoft Update, you can find and install all
these updates—not just the critical ones. Often, these updates will improve your
computer's performance.
You can make life easier by automating Microsoft Update so your computer
downloads and installs all the updates without you having to worry about them.
To automate Microsoft Update:
| 1. |
In your Start menu, click Control Panel. |
| 2. |
In the Automatic Updates dialog box, check the Automatic
(Recommended) check box. You can define the time of day when your
computer checks for updates. If the computer finds any updates, it will
download and install them automatically for you. |
| 3. |
Click OK.
Automate Microsoft Update to keep your computer
up to date.

Computer viruses and spyware (hidden software that gathers information about
you without your knowledge or consent when you're using a computer) both reduce
system performance. Computer viruses can not only reduce performance, but they
can also destroy data. Any computer that accesses the Internet should have
antivirus and antispyware programs installed.
Smooth running
Follow these steps and you'll have your computer purring like a vintage Porsche
(or whatever your dream car of choice is). And the best part—maintaining your
computer is a lot less messy than an automobile. You don't even have to roll up
your sleeves.
