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.
