A couple of months ago, Microsoft announced it would simplify Windows 7 and 8.1 installs by bundling Service Pack 1 updates into a convenience rollup. The servicing models will now be modified further through a monthly patching model.
As of October 2016, Windows 7, 8.1, Server 2008 R2, Server 2012 and Server 2012 R2 will all receive monthly roll-ups. A roll-up is just a combination of individual patches into a single update, and will help reduce micro-management.
Why the Change?
Though the new policy makes things simpler for admins, it also gives them less freedom to decide which patches they want to install. Microsoft states that this ability was causing fragmentation between PCs, with different computers having different updates.
This led to several problems:
“Various combinations caused sync and dependency errors and lower update quality
Testing complexity increased for enterprises
Scan times increased
Finding and applying the right patches became challenging
Customers encountered issues where a patch was already released, but because it was in limited distribution it was hard to find and apply proactively.”
By switching, Microsoft hopes to reduce these problems, therefore improving the reliability of the operating systems. The updates will be published to Windows Update, and will utilize express packages to keep the file size small.
Security-Only and .NET Framework Updates
Microsoft will also be releasing monthly security focused updates. All of the security patches for the month will be rolled into a single update, but will only be available from ESUS and SCCM.
A similar change is coming to .NET Framework. Security and reliability updates will come in a monthly release. These changes only apply updates to the versions on your machine, however, and don't upgrade the base version. As with Windows, a security-only patch will also apply.
The Microsoft Update Catalog is changing too, and will be ditching the Active X requirement. Finally, new documentation is coming that will reflect all of the changes mentioned.
