Autopatcher has been around for years.
It's a program that downloads updates from Microsoft so they can be kept to install later. It also has a program that checks to see what updates are installed, then manages installation of the updates the user selects.
It's very useful for maintaining PCs that have slow internet connections and for when there's a download limit on a connection and also for when several PCs need updating.
I have a USB stick with Autopatcher folders for different versions of Windows, one for MS Office and one for updates and addons common to several versions of Windows.
