* All updates released that month
* All "security" updates released that month
* No updates
There's a new telemetry update in your "security" patch? Tough shit. You want Driver Update A, but Driver Update B causes random blue-screens? Deal with it.
Further simplifying servicing models for Windows 7 and Windows 8.1
Monthly Rollup
From October 2016 onwards, Windows will release a single Monthly Rollup that addresses both security issues and reliability issues in a single update. The Monthly Rollup will be published to Windows Update (WU), WSUS, SCCM, and the Microsoft Update Catalog. Each month’s rollup will supersede the previous month’s rollup, so there will always be only one update required for your Windows PCs to get current. i.e. a Monthly Rollup in October 2016 will include all updates for October, while November 2016 will include October and November updates, and so on. Devices that have this rollup installed from Windows Update or WSUS will utilize express packages, keeping the monthly download size small.
Over time, Windows will also proactively add patches to the Monthly Rollup that have been released in the past. Our goal is eventually to include all of the patches we have shipped in the past since the last baseline, so that the Monthly Rollup becomes fully cumulative and you need only to install the latest single rollup to be up to date. We encourage you to move to the Monthly Rollup model to improve reliability and quality of updating all versions of Windows.
We are planning to add these previously shipped patches over the next year and will document each addition so IT admins know which KBs have been included each month.
Security-only updates
Also from October 2016 onwards, Windows will release a single Security-only update. This update collects all of the security patches for that month into a single update. Unlike the Monthly Rollup, the Security-only update will only include new security patches that are released for that month. Individual patches will no longer be available. The Security-only update will be available to download and deploy from WSUS, SCCM, and the Microsoft Update Catalog. Windows Update will publish only the Monthly Rollup – the Security-only update will not be published to Windows Update. The security-only update will allow enterprises to download as small of an update as possible while still maintaining more secure devices.
Update documentation changes
To bring consistency to the release notes model introduced with Windows 10, we will also be updating our down-level documentation to provide consolidated release notes with the Rollups for all supported versions of Windows. We’ll extend and provide release notes for monthly rollup updates and also the security-only updates that will be introduced from October 2016.
