Using passwords

A password is a group of characters that you choose to secure the computer information. Several types of passwords can be set, depending on how you want to control access to your information. Passwords can be set in the Windows Vista operating system on the computer.

COMPAQ CQ2100 - Using passwords - 1

CAUTION: To avoid being locked out of the computer, record each password you set. Because passwords are not displayed as they are set, changed, or deleted, it is essential to record each password immediately and store it in a secure place. Do not store passwords in a file on the computer.

You can use the same password for more than one Windows Vista security feature. A password set in Windows Vista must be entered at a Windows Vista prompt.

For information on Windows Vista passwords: Click the Windows Vista start button on the taskbar, click Help and Support, and then type passwords into the Search Help box and press Enter. See "Using the Onscreen Help and Support Center" on page 35.

Using antivirus software

When you use the computer for e-mail, network, or Internet access, you expose it to computer viruses. Computer viruses can disable or damage the operating system, software programs, or computer utilities.

Antivirus software can detect most viruses, remove them, and, in most cases, repair any damage that they have caused. To provide ongoing protection against newly discovered viruses, you must keep the antivirus software up to date.

The antivirus program, which is preinstalled on the computer, includes antivirus and firewall components. The software includes a free trial subscription of protection updates. To protect the computer against new viruses beyond the trial period, purchase an extended update service. Instructions for using and updating the antivirus software, and for purchasing extended update service, are provided within the program.

For more information about computer viruses: Click the Windows Vista start button on the taskbar, click Help and Support, and then type viruses into the Search Help box and press Enter. See "Using the Onscreen Help and Support Center" on page 35.

Using firewall software

When you use the computer for e-mail, network, or Internet access, unauthorized persons may be able to gain access to information about you, your computer, and your data. To protect your privacy, use firewall software:

Windows Vista includes firewall software preinstalled on the computer.
The antivirus program, which is preinstalled on the computer, includes a firewall program.

Firewall features include logging, reporting, and automatic alarms to monitor all incoming and outgoing communications.

Under some circumstances, a firewall can block access to Internet games, interfere with printer or file sharing on a network, or block authorized e-mail attachments. To solve the problem temporarily, disable the firewall, perform the task that you want to perform, and then enable the firewall again. To resolve the problem permanently, reconfigure the firewall.

Configuring the Computer for Automatic Microsoft Software Updates

Microsoft continually updates the Windows Vista operating system. Run Windows Vista Update monthly to install these updates, or keep the operating system up to date by using the Automatic Updates feature.

When you are connected to the Internet, Windows Vista Update automatically notifies you (through a pop-up message or icon in the notification area) when critical updates are available. When you see the Windows Vista Update message, allow the updates to download to your system. If you update the system weekly, or even monthly, the time required for download is minimal.

COMPAQ CQ2100 - Configuring the Computer for Automatic Microsoft Software Updates - 1

CAUTION: To reduce the risk of information damage or loss from security breaches and computer viruses, install all critical updates from Microsoft as soon as you receive an alert.

Additional updates to the operating system and other software may have become available after the computer was shipped. Download all available updates and install them onto the computer.

Setting Up User Accounts

When you share a computer with several people, you can set up a user account for each computer user. Windows Vista uses the information in the user account to determine what files and folders the computer user can access, when they can make changes to the computer, and their personal preferences. Each person can access only their own files and settings.

You, as the administrator, set the privileges for each computer user when you set up the user account. For example, you can set the software programs that the user is allowed to access. Windows Vista provides three types of user accounts:

Administrator:

Is allowed to change account types for other users, to change passwords, to change system-wide settings, to access all files on the computer, and to install software and drivers that are compatible with Windows Vista.

(Windows Vista requires at least one administrator user account.)

Limited - Standard User:

Is not allowed to change other user settings or passwords. A limited account may not be able to install or run some software.
Is allowed to change the limited account picture, and to create, edit, or delete the account password.

Guest:

Is allowed to use most software and change system settings that do not affect other users or the security of the computer.
Is not allowed to change other user settings or passwords, or install software.
Does not have access to password-protected files, folders, and settings.

Creating multiple user accounts on the same computer has certain advantages, as well as some drawbacks.

Advantages to multiple user accounts:

Ability to create individual user settings
Ability to limit access to software for certain users

Drawbacks to multiple user accounts:

More memory (RAM) usage
Multiple Temporary Internet Files folders to remove during Disk Cleanup
More data to back up
Longer time to complete virus scan

To create or change a user account:

1 Click the Windows Vista start button on the taskbar, and then click Control Panel.
2 Under User Accounts and Family Safety, click Add or remove user accounts. Click Continue in the User Account Control window.
3 Click Create a new account, or click the account user name you want to change.
4 Follow the onscreen instructions or click an action to proceed.

Guidelines for Installing Software and Hardware Devices

After you set up the computer and complete the initial setup, you may want to install additional software programs or hardware devices. Keep in mind the following important guidelines:

Before installation, make a restore point by using the Microsoft System Restore program. The restore point is a snapshot of the computer settings. By using System Restore, you ensure that you have a stable set of settings to use.
Choose software that is compatible with the computer; check the operating system, memory, and other requirements listed for the new software.
Install the new software according to the directions provided by the software manufacturer. If you need help, check the manufacturer documentation or customer service information.
For antivirus software, uninstall the existing software program before reinstalling it or installing a new antivirus program.

NOTE: Use only licensed original software. Installing copied software may be illegal, or may result in an unstable installation, or it may infect the computer with a virus.

Connecting USB devices

Connect USB peripheral devices to the computer by using any available USB connector. These peripheral devices include printers, scanners, video cameras, digital photo cameras, memory card readers, and personal digital assistants (PDAs) or handheld computers. Refer to the documentation that came with your device for more information.

NOTE: Some peripheral devices are not included with the computer.

COMPAQ CQ2100 - Connecting USB devices - 1

Transferring Files and Settings from an Old Computer to Your New Computer

Maintenance

This section includes information about tasks you can perform to help ensure trouble-free operation of your computer, and to ease the recovery of important information on your computer if problems arise in the future.

Maintenance tasks

It is important that you perform simple maintenance of your computer to ensure that it works at peak performance.

Weekly

Software CleanupUsing Disk Cleanup or safe third-party cleaning tools removes junk files and temporary files that accumulate and slow down your system. Also, check for programs you no longer need and uninstall them.
DefragmentationRunning Disk Defragmenter keeps your hard disk in good condition, as well as improves system performance. Frequently performing this task does not harm your system.
Virus ScanPerforming a full virus scan every week can catch anything that may have slipped through unnoticed. Most anti-virus products have a scheduling feature to keep track of this automatically.

Monthly

Hardware CleanupThoroughly clean the inside and outside of your computer.
Software UpdatesUsing Windows Updates can fix operating system bugs and improve performance. Also, be sure to check for driver updates for your hardware and new versions of your favorite programs.
Hard Disk DiagnosticSometimes a failing hard disk can be caught beforehand, saving you a lot of surprises in the future.

Yearly

System RecoveryIn time, your system may still get bogged down, depending on the usage of the computer. Use System Recovery to wipe your Windows® operating system installation clean, restoring it to the original configuration when you first powered up your system. Remember to make a backup first! Before proceeding with a recovery, see “System Recovery” on page 63 for further details.

Creating data backup discs

Use CD or DVD recording (or burning) software that is installed on your computer to create backup discs of important information, including personal files, e-mail messages, and Web site bookmarks. You can also move data to an external hard disk drive.

When writing data to a backup disc, use software that includes write verification functionality. This feature compares the data on your hard disk drive with the data copied to the disc to ensure it is an exact copy. Depending on your disc recording software, you may need to manually enable this feature (refer to the software documentation).

If you encounter recording issues, try alternate media (different types or brands). Also, use the Windows Explorer tool to view your files and verify content was copied over. To open Windows Explorer, right-click the Windows Vista start button, and then click Explore.

Creating system recovery discs

This is a one-time procedure that you should perform while your computer is working properly. If you encounter problems with your computer later, you can restore it to its original factory settings by using the system recovery discs that you created. Refer to "Creating recovery discs" on page 63 for details.

Maintenance tasks to improve performance

These maintenance tasks may improve computer performance. Perform them as needed.

Remove unused programs, which take up memory space and may slow down the computer.
Use Windows Update to check for updates or to schedule automatic updates.
■ Run the Disk Cleanup program to free up file storage space on your computer hard disk drive by removing temporary and unused files.
■ Run the Disk Defragmenter program to consolidate together any fragmented files stored on your hard disk drive. This does not affect the location of the files and folders on your computer, but improves the file retrieval time when you open a file.
Check the hard disk drive for errors by selecting Error-checking from the Tools tab in the Windows Vista Properties window for the Computer.

For more information, search for the topic in the Help and Support Center. See "Using the Onscreen Help and Support Center" on page 35.

Keeping the computer free of dust and dirt, and heat

Keeping your computer system free of dust and dirt, and heat will prolong its life. Dust, pet hair, and other particles can build up, creating a blanket effect; as a result, components can overheat, or, in the case of the keyboard and mouse, not work smoothly and effectively. Check your system once a month for visible signs of dust and debris, and clean it about once every three months.

Cleaning the computer and monitor

1 Unplug the computer from its power source.
2 Unplug the monitor from its power source.
3 Use a clean, dry cloth to dust the computer case and the monitor.
4 Use a clean cloth dampened with warm water to wipe the computer case and the monitor case clean.

Do not use water on the monitor screen.

NOTE: If there is sticker residue or a spill on the computer or monitor case, use isopropyl or rubbing alcohol and a lint-free cloth to remove it.

5 Use a clean cloth to dry the computer and monitor case.
6 Use a clean, dry cloth to clean the monitor screen, or, for more thorough cleaning use an antistatic screen cleaner and a clean cloth.

Cleaning the computer vents

Air vents keep the computer and monitor cool. To maintain efficient air flow, keep these vents clean by using a small battery-powered vacuum cleaner. (A battery-powered vacuum cleaner eliminates the risk of electric shock.)

1 Run the vacuum over the vents in the computer case and the monitor case.
2 Remove any debris that has accumulated in and around the computer connectors (for example, the Ethernet and USB connectors).

Cleaning the keyboard and mouse

When cleaning the keyboard keys, use a low setting on the battery-powered vacuum cleaner, to avoid removing key caps and springs.

Vacuum between the keys of the keyboard and along the grooves.
2 Use a clean, dry cloth and isopropyl alcohol to clean buildup on the keyboard keys and along its edges.
3 Wipe the body of the mouse and the mouse cord with cleaning wipes or a cloth and cleanser.

If you have a roller ball mouse, clean the ball and rollers inside:

1 Turn the mouse upside down.
2 Rotate the ball-cover ring counterclockwise to remove the ring and release the roller ball.
3 Rinse the roller ball with soap and warm water.
4 Clean the rollers inside the mouse with a cotton swab dampened with isopropyl alcohol.
5 After the roller ball and rollers are completely dry, replace the ball and ball-cover ring.

System Recovery

System recovery completely erases and reforms the hard disk drive, deleting all data files you have created. System recovery reinstalls the operating system, programs, and drivers. However, you must reinstall any software that was not installed on the computer at the factory. This includes software that came on CDs included in the computer accessory box, and software programs you installed after purchase.

You must choose one of the following methods to perform a system recovery:

  • Recovery Image — Run the system recovery from a recovery image stored on your hard disk drive. The recovery image is a file that contains a copy of the original factory-shipped software. To perform a system recovery from a recovery image, see "System recovery from the Windows Vista Start Menu" on page 64.

NOTE: The recovery image uses a portion of the hard disk drive that cannot be used for data storage.

Recovery Discs - Run the system recovery from a set of recovery discs that you create from files stored on your hard disk drive. To create recovery discs, see the next section.

Creating recovery discs

Complete the procedure described in this section to create a set of recovery discs from the recovery image stored on your hard disk drive. This image contains the operating system and software program files that were originally installed on your computer at the factory.

You can create only one set of recovery discs for your computer. Furthermore, the recovery discs you create can be used only with your computer.

After creating the recovery discs, you can delete the recovery image if you want to make extra space available on your hard disk drive.

NOTE: Do not delete the recovery image until you have made recovery discs.

Choosing recovery discs

To create recovery discs, your computer must have a DVD writer.

Use DVD+R, DVD-R, DVD+R DL, or DVD-R DL blank media to create your system recovery discs.
You cannot use DVD+RW, DVD-RW, DVD+RW DL, DVD-RW DL, or CD discs to create recovery discs.

Use high-quality discs to create your set of recovery discs. The verification standard for the recovery disc creation process is very high. You may see error messages such as Recording failure when writing disc or Error detected during disc verification.

Your discs may be rejected if they are not defect-free. You will be prompted to insert a new blank disc to try again. It is normal that some of your discs may be rejected.

The number of discs in the recovery disc set depends on your computer model (typically 1-3 DVD discs). The Recovery Disc Creator program tells you the specific number of blank discs needed to make the set.

The process takes some time to verify that the information written on the disc is correct. You can quit the process at any time. The next time you run the program, it resumes where it left off.

To create recovery discs:

1 Close all open programs.
2 Click the Windows Vista start button, click All Programs, click PC Help & Tools, and then click Recovery Disc Creation.
3 Follow the onscreen instructions. Label each disc as you make it (for example, Recovery 1, Recovery 2).
4 Store the recovery discs in a safe place.

a Click the Windows Vista start button, click All Programs, click the HP folder, and then click HP Update.
b Follow the onscreen instruction to download driver and software updates.

8 If you performed a backup before the system recovery, copy the backup data files from the backup media to your hard disk drive.
9 Ensure your system is running up-to-date security software.
