INTRODUCTION
This article discusses changes to the WSUSScan.cab file. The Microsoft Systems Management Server Inventory Tool for Microsoft Updates (ITMU) and Microsoft Baseline Security Analyzer (MBSA) use this file for offline security update detection.



MORE INFORMATION
ITMU and MBSA use the WSUSScan.cab file to support offline scanning by managed systems. The WSUSScan.cab file has grown with each new security release. After August 8, 2006, the files that are contained in this file have approached the maximum for a single .cab file. Therefore, Microsoft is reducing the size of the WSUSScan.cab file by removing security updates for unsupported platforms, superseded security updates, and tools that are no longer needed.

We will repeat this reduction to keep the file size well within the limit. These reductions will not affect the security of customers' systems. Also, these reductions will not affect customers' ability to keep systems up to date. In support of the October security update, we have reduced the size of the .cab file to support the latest security updates. The updates that are being removed are listed in the &quot;Updates with multiple newer updates&quot; table.

Windows Server Update Services (WSUS), Automatic Update (AU), Microsoft Update, and Windows Update are not affected by these changes because these services use an online mechanism for distribution. Additionally, WSUS maintains a local database for update information. Users of new WSUS installations of WSUS will notice that these deprecated updates no longer synchronize with Microsoft Update.

Systems Management Server 2003 customers who use the Inventory Tool for Microsoft Updates will notice that deprecated updates are removed from the SMS database because of this change. This behavior is by design and occurs naturally when newer updates replace older updates. An older update is removed from the database when a newer update is installed. Then, the update status is reported up the SMS hierarchy.

This change will be immediately noticeable as older versions of the Microsoft Malicious Software Removal Tool (MSRT) are removed from the SMS database after an SMS client scans by using the latest catalog. Because the MSRT is a cumulative release, each new version replaces the earlier version.

The following list of deprecated updates will be updated every time we remove older updates from the WSUSScan.cab file.
