Windows server Security Only Patch and Monthly rollup (cumulative for how long?)

Occasional Contributor

Hello, 

I can't find the answer to this qeustion. 

Security Only Patcha dn Monthly rollup are said it's cumulative, but;

1. How many months of patches does the recent patch have in it? Only previous month, 3 months, 1 year or since the release of the Windows server edtion, for example, 10/2013, 7 years ago (Windows 2021 R2)?

2. When I search February, 2021 KB4601349 (Security-only update) patch in Microsoft Update Catalog, it doesn't show the delta update (for only this month's patches). How can I obtain delta update as I have to push to multiple servers monthly?

Security-only update

An update that collects all the new security updates for a given month and for a given product, addressing security-related vulnerabilities. It's 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. It will be classified as an Important update.

 (The Security Only update does not contain fixes from previous months)

 

Monthly Rollup

A tested, cumulative set of updates. They include both security and reliability updates that are packaged together and distributed over the following channels for easy deployment:

  • Windows Update
  • WSUS
  • System Center Configuration Manager
  • Microsoft Update Catalog

The Monthly Rollup is product-specific and addresses both new security issues and nonsecurity issues in a single update. It 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. It will automatically download and install if your Windows Update settings are configured to automatically download and install Important updates.

(Microsoft Monthly Rollup: Contains all new security fixes for the month plus all security and non-security fixes from all previous Monthly Rollups)
