11.3. How Monthly Rollups Simplify Update Management

Monthly rollups simplify update management by consolidating multiple updates into a single package, reducing the time and effort required to keep systems up-to-date. This is particularly beneficial for organizations with large numbers of systems to manage. Microsoft documentation provides details about managing updates using monthly rollups.

12. Preview of Monthly Rollups: Testing Updates Before General Release

Preview of Monthly Rollups are tested, cumulative sets of new updates packaged together and distributed ahead of the next Monthly Rollup release. This allows customers to proactively download, test, and provide feedback. Microsoft uses preview rollups to gather feedback on upcoming updates.

12.1. The Purpose of Preview Rollups

Preview rollups allow users to test new updates in a non-production environment before they are released to the general public. This helps identify potential issues and ensures that the updates are stable and reliable. According to a report by Forrester Research, preview programs improve software quality.

12.2. Differences Between Preview and Standard Rollups

Preview rollups differ from standard rollups in that they are released ahead of the official monthly rollup and are classified as “Optional” updates. They include new non-security updates and fixes from the latest monthly rollup. Microsoft documentation provides details about the differences between these update types.

12.3. How to Provide Feedback on Preview Rollups

Users can provide feedback on preview rollups through the Windows Feedback Hub, allowing them to report issues, suggest improvements, and contribute to the overall quality of the updates. Microsoft encourages users to participate in the preview program to help improve the Windows operating system.

13. Servicing Stack Updates (SSU): Ensuring Reliable Update Installation

Servicing Stack Updates (SSU) are updates to the code that installs other operating system updates. The servicing stack contains the component-based servicing stack (CBS), a key underlying component for Windows deployment. Microsoft releases SSUs to improve the reliability of the update process.

13.1. The Role of the Servicing Stack

The servicing stack is responsible for installing other operating system updates, ensuring that the update process is reliable and efficient. It contains the CBS, which is used for various elements of Windows deployment. Microsoft documentation provides detailed information about the servicing stack.
