After scanning the system, KB890830 repeatedly detects that it requires remediation, even though it has been previously installed. This KB (Knowledge Base) is related to the Windows Malicious Software Removal Tool, which continually receives updates.
This article provides more information about the repeated detection of KB890830 as a needed remediation.
- Due to the nature of this update, Microsoft has continued to use the same KB.
- Every time there is an update for the Windows Malicious Software Removal Tool, the same KB is referenced.
- The title or summary of the update should show the month or date of the missing update.
- As a Cumulative Update, only the newest release is detected or needed.
- Additionally, there have been times where the patch detection is broken on Microsoft's end, which causes LanGuard to report that the patch was successful in installation, and yet still needed.
- This most recently occurred with the November 2019 updates and was resolved upon Microsoft publishing the December 2019 Cumulative Updates.
- As this was broken on Microsoft's end, the wsusscn2.cab file and offline scans continually detected the patch as needed.
- Since LanGuard also performs these types of offline scans, we have also reported it as needed, even after it was installed.
