Download Windows Xp Service Pack 3
If you are running antivirus software
Warning This workaround may make a computer or a network more vulnerable to attack by malicious users or by malicious software such as viruses. We do not recommend this workaround but are providing this information so that you can implement this workaround at your own discretion. Use this workaround at your own risk.
• If the configuration of your antivirus software prevents certain system files from being changed, the Windows XP SP3 installation may fail. Try temporarily disabling your antivirus software. To do this, right-click your antivirus program icon, and then click Disable. This icon typically appears in the lower right corner of the computer screen.
• If you disable your antivirus software before you install Windows XP SP3, make sure that you know the risks that are involved, and make sure that you enable the antivirus software after Windows XP SP3 is installed.
Note An antivirus program is designed to help protect your computer from viruses. You must not download or open files from sources that you do not trust, visit Web sites that you do not trust, or open e-mail attachments when your antivirus program is disabled.

Steps to take before you install Windows XP SP3
1. Start your computer, and then log on as an administrator.
Note Administrators have complete and unrestricted access to the operating system and to its settings. You can use the Administrator user name to log on, or you can use another account that is a member of the Administrators group. To determine the groups to which you belong, click Start, click Control Panel, and then click User Accounts.
2. If your computer is running on battery power, plug it in so that your computer does not lose power during the installation.
3. If you use Fast User Switching, make sure all other users are logged off. For more information, see “Fast User Switching” in Windows XP Help and Support Center on your computer.
4. We recommend that you perform a full backup of the files that you have on your computer to an external location, such as an external hard disk, DVD, CD, USB flash drive, or network folder. You can use the Backup and Restore Wizard to back up documents, pictures, and other files. For more information, see “Backing up files and folders” in Help and Support Center.
5. If your computer is running Windows XP Professional, we recommend that you create an Automated System Recovery (ASR) set before you begin the installation. This will help you repair your setup if the installation fails. For more information, see “To create an Automated System Recovery set using Backup” and “To recover from a system failure using Automated System Recovery” in Help and Support Center.
Note If your computer is running Windows XP Home Edition, ignore this step. ASR is not available for Windows XP Home Edition.
6. Exit all open programs.
