QNumbers Explained

Version 3



    This document explains QNumbers and the format used for Microsoft and Third Party patches




    Microsoft Patches


    The QNumber is the Knowledge Base (KB) number used to identify Microsoft patches. The format is the KB Number, with Q replacing KB


    When searching Protect for a Microsoft patch you can search in the patch view search area. Type in the patch number excluding the KB.



    Third Party Patches


    For third party patches we will generally follow the vendors criteria. For example, Adobe Flash Player 11.8.800.175 would be QAF118800175 for Adobe Flash Player 11.8.800.175


    If you notice there is an N following the QNumber, this denotes that it is a Software Distribution type patch. In the images below, one is a Security Patch and the other is a Software Distribution even though they have the same Qnumber. More information about Software Distributions can be found here:

    The Security Tools patch type is used for hotfixes or other tools like the Microsoft Malware Tool.  The Qnumber without the U will apply the tool and the Qnumber with the U will disable the disable it.


    Please note, including a Qnumber with and without the U will cause a install and uninstall loop. Please see this document for more information: http://community.shavlik.com/docs/DOC-23049
