Windows XP Service Pack 2 is not available to install from Windows Update and is not offered by Automatic Updates

Method 1: If you are not running Windows XP or Windows XP SP1

If you are already running Windows XP SP2, you will not see Windows XP SP2 on the Windows Update Web site.

If you are not sure if you are running Windows XP Service Pack 2, click Start, click Run, type winver, and then click OK. Look for the words "Service Pack 2" at the end of the line that begins with "Version 5.1."

If you are running another version of Windows, such as Microsoft Windows 95, Microsoft Windows 98, Microsoft Windows Millennium Edition, Microsoft Windows NT, Microsoft Windows 2000, or Microsoft Windows Server 2003, you cannot install Windows XP SP2. You must install Windows XP before you can install Windows XP SP2.

Method 2: If T.V. Media from Total Velocity Corporation is installed on your computer

We discovered a compatibility issue between Windows XP SP2 installation and a third-party advertising program that is named T.V. Media after Windows XP SP2 was completed. The issue occurs when you have T.V. Media installed on your computer, and you try to install Windows XP SP2. In this case, you receive the following error message and the Windows XP SP2 installation process fails:

To help you avoid a failed Windows XP SP2 installation from Windows Update or from Automatic Updates, we have blocked the download of Windows XP SP2 to computers that have T.V. Media installed until T.V. Media is removed or Critical Update 885523 is installed to fix the issue.

If you want to install Windows XP SP2, you must completely remove T.V. Media from your system or install the 885523 update. The simplest way to remove T.V. Media is to use the Adware T.V. Media Program Removal Tool (KB 886590) that removes T.V. Media. After you remove T.V. Media or install the 885523 update, Windows XP SP2 will be available to install from Windows Update or from Automatic Updates. For more information about the Adware T.V. Media Program Removal Tool, click the following article number to view the article in the Microsoft Knowledge Base:

Notes

• T.V. Media is typically installed when you install other programs or when you visit Internet Web sites that are supported by T.V. Media advertising. Because of this installation behavior, T.V. Media may be unwanted software.

• If you want to reinstall T.V. Media after you install Windows XP SP2, you must locate the program or the Web site that originally installed T.V. Media.

• If you have already installed Windows XP SP2 on a computer that is running T.V. Media, click the following article number for information about how to recover your system:

• We recommend that you install and run a tool that removes unwanted software before you install Windows XP SP2 on your computers. A variety of tools that detect and remove unwanted software from a computer are available from third-party companies. For more information about these tools, visit the following Microsoft Web site:

Method 3: If you are running an Intel Pentium 4 or Intel Celeron D processor that is based on Prescott C-0 stepping

If your computer contains an Intel Pentium 4 or Intel Celeron D processor that is based on Prescott C-0 stepping, and Critical Update 885626 is not yet installed, Windows Update will not offer to download Windows XP SP2. Microsoft and Intel have released an updated processor driver that will help prevent this installation failure. We recommend that you install Critical Update 885626, and rescan your system with Windows Update to install Windows XP SP2.

To determine whether your computer has this previously mentioned processor, click Start, click Run, type msinfo32, and then press ENTER. Look for the line that begins with “Processor" in the right pane of the System Information window. If your computer has this blocked processor, MSInfo32 will display the following text:

Processor x86 Family 15 Model 3 Stepping 3 If your processor is a Family 15 Model 3 Stepping 3 processor, you will not be automatically offered Windows XP SP2 unless Critical Update 885626 is installed. This problem occurs because certain processor and BIOS combinations exist where the BIOS does not correctly support the specific processor model. Only a small fraction of these processors are installed in systems that have an incorrect BIOS. However, all systems that have these processors are blocked until the update is installed.
