According to Microsoft’s announcement, convenience rollups to service packs except that they contain no new features. They contain “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.” After this is installed, users will only need to install future updates. Microsoft also announced today that non-security updates for Windows 7 SP1, Windows 8.1, Windows Server 2008 R2 SP1, Windows Server 2012 and Windows Server 2012 R2 will be available as a single update delivered monthly, which will be available through Windows Update. Each month, going forward, Microsoft will release a single update containing all of the non-security fixes for that month “to improve the reliability and quality of our updates,” according to the blog post. “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,” Microsoft explained. Microsoft also notes that in the coming months, you won’t be able to download updates from the Download Center anymore. Also, the new convenience rollup is available for download from the Microsoft Update Catalog.
