Microsoft releases a monthly Security Release ISO image which contains the security releases of a particular month packed in a single ISO disc image (sometimes in multiple depending on size as they are always released as single DVD images).
The benefit of this approach is not really obvious for home computer users running just one version of the Windows operating system but if you administrate a network of Windows PCs, be it home or large corporate, then you may find it useful as it provides you with access to all patches of the month.
If you would not have access to the patch DVD, you would have to download the patches individually instead which may take some time, especially if you need to download different versions of a patch for Windows systems.
The size of the ISO image is usually
around 450 Megabytes and it contains sometimes only two or three patches in total a couple of Gigabytes. That means, end users are better off using Windows Updates to get their updates while administrators should definitely evaluate the possibility of using the Security Release ISO Images.
Please note that the size has increased significantly in recent time and that the images may even span across multiple discs now.
This DVD5 ISO image is intended for administrators that need to download multiple individual language versions of each security update and that do not use an automated solution such as Windows Server Update Services (WSUS). You can use this ISO image to download multiple updates in all languages at the same time.
Tip: Make sure you select the right language when you are downloading the patches.
