  • Hello Shahin,

    The KB4512506 Monthly Rollup will contain the KB4512486 Security-only update.

    If you read carefully under the "Improvements and fixes" section of both KB articles, they state the same things, although the monthly has something more.

    Here's some information about these two:

    Monthly Rollup

    Definition: A tested, cumulative set of updates. They include both security and reliability updates that are packaged together and distributed over Windows Update, WSUS, System Center Configuration Manager and Microsoft Update Catalog for easy deployment. The Monthly Rollup is product specific, addresses both new security issues and nonsecurity issues in a single update and will proactively include updates that were released in the past. Security vulnerabilities are rated by their severity. The severity rating is indicated in the Microsoft security bulletin as critical, important, moderate, or low. This Monthly Rollup would be displayed under the title Security Monthly Quality Rollup when you download or install. This Monthly Rollup will be classified as an "Important" update on Windows Update and will automatically download and install if your Windows Update settings are configured to automatically download and install Important updates.

    Security-only update

    Definition: An update that collects all the new security updates for a given month and for a given product, addressing security-related vulnerabilities and distributed through Windows Server Update Services (WSUS), System Center Configuration Manager and Microsoft Update Catalog. Security vulnerabilities are rated by their severity. The severity rating is indicated in the Microsoft security bulletin as critical, important, moderate, or low. This Security-only update would be displayed under the title Security Only Quality Update when you download or install the update and will be classified as an "Important" update.


    Reference:
    Description of the standard terminology that is used to describe Microsoft software updates

    So in simple words, a security-only update contains this months security updates only, it's a lightweight update.

    While a monthly rollup contains this months reliability and security updates and all previous months reliability and security updates.

    Best regards,
    Leon
