When you try to install Windows updates from the Windows Update website, the Microsoft Update website, or by using Automatic Update, you receive a message that the update is not installed successfully. Additionally, the update is not displayed in the update history.
You may experience this issue in the following scenarios:
Scenario 1You try to install updates after you repair a Windows XP installation by using the Windows XP CD.
Scenario 2You perform the following operations before you try to install Windows updates:
- You perform a new installation of Windows XP Service Pack 2 (SP2).
- You do not restart the computer.
- You go to the Windows Update website, or the Microsoft Update website.

- You install Windows XP Service Pack 3 (SP3).
- You try to install Windows updates after the installation of Windows XP SP3.
If you are experiencing other issues related to Windows Update, see the "More Information" section to find appropriate solutions.
This issue occurs because the Wups2.dll file that is included in the latest version of Windows Update is installed incorrectly.
For scenario 1, the registry entries that correspond to the Wups2.dll file are missing after the repair installation of Windows XP. The release version of Windows XP does not contain the Windows Update software.
For scenario 2, the registry entries that correspond to Windows Update are changed back to the Windows XP SP2 version if you did not restart the computer before you installed Windows XP SP3. The registry entries for the Wups2.dll file are changed to point to the Wups.dll file that is included in the release version of Windows XP SP2.
To resolve this problem, use one of the following methods.
Method 1: Download and install the Windows Update Agent
