Windows Vista System Update Readiness Tool (KB947821) [April 2008]

The Windows Vista System Update Readiness Tool (KB947821)

Overview

This tool is being offered because an inconsistency was found in the Windows servicing store which may prevent the successful installation of future updates, service packs, and software. This tool checks your computer for such inconsistencies and attempts to resolve issues if found.

This update is provided to you and licensed under the Windows Vista License Terms.

Update information

After you download the System Update Readiness Tool, it runs a onetime scan for inconsistencies that might prevent future servicing operations. This scan typically takes less than 15 minutes to run. However, the tool might take significantly longer on some computers. The Windows Update progress bar is not updated during the scan, and progress seems to stop at 60% complete for some time. This behavior is expected. The scan is still running and you should not cancel the update.

More information

System resources, such as file data, registry data, and even in-memory data, can develop inconsistencies during the lifetime of the operating system. These inconsistencies might be caused by various hardware failures or might be caused by software issues. In some cases, these inconsistencies can affect the Windows servicing store, and they can cause software updates not to work. The System Update Readiness Tool tries to resolve these inconsistencies.

What does the System Update Readiness Tool do?

The System Update Readiness Tool verifies the integrity of the following resources:

• Files that are located under the following directories:

• %SYSTEMROOT%\Servicing\Packages
• %SYSTEMROOT%\WinSxS\Manifests

• Registry data that is located under the following registry subkeys:

• HKEY_LOCAL_MACHINE\Components
• HKEY_LOCAL_MACHINE\Schema
• HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Component Based Servicing

Note: This list may be updated at any time.

When the System Update Readiness Tool detects incorrect manifests, files, or registry data, it might replace the incorrect data with a corrected version.

What Windows Update installation errors can the System Update Readiness Tool potentially address?

The following table lists error messages that you might receive when you try to install a software update. These errors might be caused by a system irregularity that the System Update Readiness Tool might be able to resolve. However, the tool might be unable to fix all instances in which these errors occur.
