We’re happy to announce today that we’re making available a new convenience rollup for Windows 7 SP1 that will help. This convenience rollup package, available to download from http://catalog.update.microsoft.com/...aspx?q=3125574, contains all the security and non-security fixes released since the release of Windows 7 SP1 that are suitable for general distribution, up through April 2016. Install this one update, and then you only need new updates released after April 2016.

And since this update can be injected into Windows 7 SP1 media, it’s fully supported to mount a Windows 7 SP1 image (WIM file), then inject this update into it. See https://technet.microsoft.com/en-us/...(v=ws.10).aspx for the details of how to do this.

This convenience update is completely optional; it doesn’t have to be installed and won’t even be offered via Windows Update – you can choose whether or not you want to use it.

We hope that you find this convenience rollup package useful. This same convenience rollup also applies to Windows Server 2008 R2.

Monthly Rollups

Also today we are announcing that non-security updates for Windows 7 SP1 and Windows 8.1 (as well as Windows Server 2008 R2 SP1, Windows Server 2012 and Windows Server 2012 R2) will be available as a monthly rollup (fixes rolled up together into a single update). Each month, we will release a single update containing all of the non-security fixes for that month. We are making this change – shifting to rollup updates, to improve the reliability and quality of our updates.

These fixes will be available through Windows Update, WSUS, and SCCM as well as the Microsoft Update catalog. We hope this monthly rollup update simplifies your process of keeping Windows 7, and 8.1 up-to-date.
