Microsoft Baseline Security Analyzer
To verify that a security update has been applied to an affected system, you may be able to use the Microsoft Baseline Security Analyzer (MBSA) tool. See the section, Detection and Deployment Tools and Guidance, earlier in this bulletin for more information.
File Version Verification
Because there are several versions of Microsoft Windows, the following steps may be different on your computer. If they are, see your product documentation to complete these steps.
- Click Start, and then click Search.
- In the Search Results pane, click All files and folders under Search Companion.
- In the All or part of the file name box, type a file name from the appropriate file information table, and then click Search.
- In the list of files, right-click a file name from the appropriate file information table, and then click Properties.
Note Depending on the version of the operating system or programs installed, some of the files that are listed in the file information table may not be installed. - On the Version tab, determine the version of the file that is installed on your computer by comparing it to the version that is documented in the appropriate file information table.
Note Attributes other than the file version may change during installation. Comparing other file attributes to the information in the file information table is not a supported method of verifying that the update has been applied. Also, in certain cases, files may be renamed during installation. If the file or version information is not present, use one of the other available methods to verify update installation.
Registry Key Verification
You may also be able to verify the files that this security update has installed by reviewing the registry keys listed in the Reference Table in this section.
These registry keys may not contain a complete list of installed files. Also, these registry keys may not be created correctly when an administrator or an OEM integrates or slipstreams this security update into the Windows installation source files.
