How to download and install the June 2015 security updates
Patches are distributed via Microsoft's automatic update system to home users worldwide. While that covers most home users, some may have blocked automatic updates from being deployed on their systems, for instance to run tests first or wait for stability reports before patches are applied.
If you have configured automatic updates, you may still want to run a check right away so that the updates can be downloaded and installed on a system running Windows right away. If you don't do that, you may wait hours before the patches are picked up automatically.
The best method to run update checks is the following:
Alternatives are provided for users who don't use automatic updates. Updates are made available on Microsoft's Download Center from where they can be downloaded. Another alternative is the monthly security ISO image that Microsoft releases.
Last but not least, third-party software is also provided to download updates and patches to systems. These third-party solutions may improve the user experience, for instance by allowing you to download patches for multiple versions of Windows from a single machine in one go.
