FYI...Device Manager may not show any devices and Network Connections may not show any network connections after you install Windows XP Service Pack 3 (SP3)

After you install Windows XP Service Pack 3 (SP3), Device Manager may not show any devices and Network Connections may not show any network connections.This problem may occur when an antivirus application is running during the installation of Windows XP SP3
This problem occurs when the Fixccs.exe process is called during the Windows XP SP3 installation. This process creates some intermediate registry subkeys, and it later deletes these subkeys. In some cases, some antivirus applications may not let the Fixccs.exe process delete these intermediate registry subkeys.
When this problem occurs, certain applications, such as Device Manager and Network Connections, may be unable to enumerate the device or the connection instances. These applications will report a blank status even though devices and connections still function as expected.

• 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..."
