Microsoft Baseline Security Analyzer is wrongly missing Service Pack 1 for Windows 7.

 

When you install a blank Windows 7 Installation and patching it with convenience Update KB3125574. Baseline security analyzer 2.3 from Microsoft reports that Service Pack 1 is missing allthough it is installed.

Environment

  • Microsoft Operating System
    • Windows 7
    • Windows 7 SP1
    • Installing it with convenience update KB3125574

Problem

Analyzing the patchlevel from the computer with the Microsoft tool “Microsoft Baseline Security Analyzer” brings the result that Service Pack 1 is missing on the computer. But is installed for sure.

Solution

Ignoring the reporting result from MBSA because it seems to be a bug in MBSA.

Explanation

  • Convenience rollup update KB3125574
    • It is an update which is including all security patches from release date from SP1 from Windows 7 (which was in 2011) and the release date from the convenience update in April 2016. The user dont have to install every single patch because it is enough to install KB3125574.
    • KB3125574 does only including security updates (no quality updates)
  • MBSA – Microsoft Baseline Security Analyzer
    • It is a free tool from Microsoft which helps to detect security gaps (users without password rotation for example) or to detect the gap between the client and the patchlevel at the WSUS or the publich Microsoft update sites.
