    							Using Internet security software
    When you use your computer to access email, a network, or the Internet, you potentially expose your
    computer to computer viruses, spyware, and other online threats. To help protect your computer,
    Internet security software that includes antivirus and firewall features may be preinstalled on your
    computer as a trial offer. To provide ongoing protection against newly discovered viruses and other
    security risks, security software must be kept up to date. It is strongly recommended that you upgrade
    the security software trial offer or purchase the software of your choice in order to fully protect your
    computer.
    Using antivirus software
    Computer viruses can disable programs, utilities, or the operating system, or cause them to function
    abnormally. Antivirus software can detect most viruses, destroy them, and in most cases, repair any
    damage they have caused.
    To provide ongoing protection against newly discovered viruses, antivirus software must be kept up to
    date.
    An antivirus program may be preinstalled on your computer. It is strongly recommended that you use
    the antivirus program of your choice in order to fully protect your computer.
    For more information about computer viruses, from the Start screen, type support, and then select
    the HP Support Assistant app.
    Using firewall software
    Firewalls are designed to prevent unauthorized access to a system or network. A firewall can be
    software you install on your computer and/or network, or it can be a combination of both hardware
    and software.
    There are two types of firewalls to consider:
    ●Host-based firewalls—Software that protects only the computer it is installed on.
    ●Network-based firewalls—Installed between your DSL or cable modem and your home network
    to protect all the computers on the network.
    When a firewall is installed on a system, all data sent to and from the system is monitored and
    compared with a set of user-defined security criteria. Any data that does not meet those criteria is
    blocked.
    Installing software updates
    HP, Microsoft Windows, and third-party software installed on your computer should be regularly
    updated to correct security problems and improve software performance. For more information, see
    Updating programs and drivers on page 58.
    Installing critical security updates
    CAUTION:Microsoft® sends out alerts regarding critical updates. To protect the computer from
    security breaches and computer viruses, install all critical updates from Microsoft as soon as you
    receive an alert.
    You can choose whether updates are installed automatically. To change the settings, from the Start
    screen, type c, and then select Control Panel. Select System and Security, select Windows
    Update, select Change settings, and then follow the on-screen instructions.
    62 Chapter 9   Securing your computer and information 
    						
    							Installing HP and third-party software updates
    HP recommends that you regularly update the software and drivers that were originally installed on
    your computer. To download the latest versions, go to 
    http://www.hp.com/go/contactHP. At this
    location, you can also register to receive automatic update notifications when they become available.
    If you have installed third-party software after you purchased your computer, regularly update the
    software. Software companies provide software updates to their products to correct security problems
    and improve functionality of the software.
    Securing your wireless network
    When you set up your wireless network, always enable security features. For more information, see
    Protecting your WLAN on page 17.
    Backing up your software applications and information
    Regularly back up your software applications and information to protect them from being permanently
    lost or damaged through a virus attack or a software or hardware failure. For more information, see
    Backing up, restoring, and recovering on page 68.
    Using an optional security cable lock
    A security cable lock, which is purchased separately, is designed to act as a deterrent, but it may not
    prevent the computer from being mishandled or stolen. Security cable locks are only one of several
    methods that should be employed as part of a complete security solution to help maximize theft
    protection.
    The security cable slot on your computer may look slightly different from the illustration in this section.
    For the location of the security cable slot on your computer, see 
    Getting to know your computer
    on page 4.
    1.Loop the security cable lock around a secured object.
    2.Insert the key (1) into the security cable lock (2).

    							11 Backing up, restoring, and recovering
    Your computer includes tools provided by HP and the operating system to help you safeguard your
    information and retrieve it if you ever need to. These tools will help you return your computer to a
    proper working state or even back to the original factory state, all with simple steps.
    This chapter provides information about the following processes:
    ●Creating recovery media and backups
    ●Restoring and recovering your system
    NOTE:This guide describes an overview of backing up, restoring and recovering options. For more
    details about the tools provided, see Help and Support. From the Start screen, type h, and then select
    Help and Support.
    Creating recovery media and backups
    Recovery after a system failure is only as good as your most recent backup.
    1.After you successfully set up the computer, create HP Recovery media. This step creates a
    backup of the HP Recovery partition on the computer. The backup can be used to reinstall the
    original operating system in cases where the hard drive is corrupted or has been replaced.
    HP Recovery media you create will provide the following recovery options:
    ●System Recovery—Reinstalls the original operating system and the programs that were
    installed at the factory.
    ●Minimized Image Recovery—Reinstalls the operating system and all hardware-related
    drivers and software, but not other software applications.
    ●Factory Reset—Restores the computer to its original factory state by deleting all
    information from the hard drive and re-creating the partitions. Then it reinstalls the
    operating system and the software that was installed at the factory.
    See 
    Creating HP Recovery media on page 69.
    2.As you add hardware and software programs, create system restore points. A system restore
    point is a snapshot of certain hard drive contents saved by Windows System Restore at a
    specific time. A system restore point contains information that Windows uses, such as registry
    settings. Windows creates a system restore point for you automatically during a Windows update
    and during other system maintenance (such as a software update, security scanning, or system
    diagnostics). You can also manually create a system restore point at any time. For more
    information and steps for creating specific system restore points, see Help and Support. From
    the Start screen, type h, and then select Help and Support.
    3.As you add photos, video, music, and other personal files, create a backup of your personal
    information. Windows File History can be set to regularly and automatically back up files from
    libraries, desktop, contacts, and favorites. If files are accidentally deleted from the hard drive and
    they can no longer be restored from the Recycle Bin, or if files become corrupted, you can
    restore the files that you backed up using File History. Restoring files is also useful if you ever
    68 Chapter 11   Backing up, restoring, and recovering 
    						
    							choose to reset the computer by reinstalling Windows or choose to recover using HP Recovery
    Manager. 
    NOTE:File History is not enabled by default, so you must turn it on.
    For more information and steps for enabling Windows File History, see Help and Support. From
    the Start screen, type h, and then select Help and Support.
    Creating HP Recovery media
    HP Recovery Manager is a software program that offers a way to create recovery media after you
    successfully set up the computer. HP Recovery media can be used to perform system recovery if the
    hard drive becomes corrupted. System recovery reinstalls the original operating system and the
    software programs installed at the factory, and then configures the settings for the programs. HP
    Recovery media can also be used to customize the system or aid in the replacement of a hard drive.
    ●Only one set of HP Recovery media can be created. Handle these recovery tools carefully, and
    keep them in a safe place.
    ●HP Recovery Manager examines the computer and determines the required storage capacity for
    the blank USB flash drive or the number of blank DVD discs that will be required.
    ●To create recovery discs, your computer must have an optical drive with DVD writer capability,
    and you must use only high-quality blank DVD-R, DVD+R, DVD-R DL, or DVD+R DL discs. Do
    not use rewritable discs such as CD±RW, DVD±RW, double-layer DVD±RW, or BD-RE
    (rewritable Blu-ray) discs; they are not compatible with HP Recovery Manager software. Or
    instead you can use a high-quality blank USB flash drive. 
    ●If your computer does not include an integrated optical drive with DVD writer capability, but you
    would like to create DVD recovery media, you can use an external optical drive (purchased
    separately) to create recovery discs, or you can obtain recovery discs for your computer from the
    HP website. For U.S. support, go to 
    http://www.hp.com/go/contactHP. For worldwide support, go
    to 
    http://welcome.hp.com/country/us/en/wwcontact_us.html. If you use an external optical drive,
    it must be connected directly to a USB port on the computer; the drive cannot be connected to a
    USB port on an external device, such as a USB hub.
    ●Be sure that the computer is connected to AC power before you begin creating the recovery
    media.
    ●The creation process can take up to an hour or more. Do not interrupt the creation process.
    ●If necessary, you can exit the program before you have finished creating all of the recovery
    DVDs. HP Recovery Manager will finish burning the current DVD. The next time you start HP
    Recovery Manager, you will be prompted to continue, and the remaining discs will be burned.
    To create HP Recovery media:
    1.From the Start screen, type recovery, and then select HP Recovery Manager.
    2.Select Recovery Media Creation, and then follow the on-screen instructions.
    If you ever need to recover the system, see 
    Recovering using HP Recovery Manager on page 72.
    Creating recovery media and backups 69 
    						
    							Restore and recovery
    There are several options for recovering your system. Choose the method that best matches your
    situation and level of expertise:
    ●If you need to restore your personal files and data, you can use Windows File History to restore
    your information from the backups you created. For more information and steps for using File
    History, see Help and Support. From the Start screen, type h, and then select Help and
    Support. 
    ●If you need to correct a problem with a preinstalled application or driver, use the Drivers and
    Applications Reinstall option of HP Recovery Manager to reinstall the individual application or

    Applications Reinstall, and then follow the on-screen instructions.
    ●If you want to restore the system to a previous state without losing any personal information,
    Windows System Restore is an option. System Restore allows you to restore without the
    requirements of Windows Refresh or a reinstallation. Windows creates system restore points
    automatically during a Windows update and other system maintenance events. Even if you did
    not manually create a restore point, you can choose to restore to a previous point, automatically
    created. For more information and steps for using Windows System Restore, see Help and
    Support. From the Start screen, type h, and then select Help and Support.
    ●If you want a quick and easy way to recover the system without losing your personal information,
    settings, or apps that came preinstalled on your computer or were purchased from the Windows
    Store, consider using Windows Refresh. This option does not require backing up data to another
    drive. See 
    Using Windows Refresh for quick and easy recovery on page 71.
    ●If you want to reset your computer to its original state, Windows provides an easy way to remove
    all personal data, apps, and settings, and reinstall Windows. 
    For more information, see 
    Remove everything and reinstall Windows on page 71.
    ●If you want to reset your computer using a minimized image, you can choose the HP Minimized
    Image Recovery option from the HP Recovery partition (select models only) or HP Recovery
    media. Minimized Image Recovery installs only drivers and hardware-enabling applications.
    Other applications included in the image continue to be available for installation through the
    Drivers and Applications Reinstall option in HP Recovery Manager.
    For more information, see 
    Recovering using HP Recovery Manager on page 72.
    ●If you want to recover the computers original factory partitioning and content, you can choose
    the System Recovery option from the HP Recovery media. For more information, see
    Recovering using HP Recovery Manager on page 72.
    ●If you have replaced the hard drive, you can use the Factory Reset option of HP Recovery
    media to restore the factory image to the replacement drive. For more information, see
    Recovering using HP Recovery Manager on page 72.
    ●If you wish to remove the recovery partition to reclaim hard drive space, HP Recovery Manager
    offers the Remove Recovery Partition option.
    For more information, see 
    Removing the HP Recovery partition on page 73.
