Incidentally I just finished building a new Win7 machine yesterday and applying all the updates. You are correct, this one wasn't caught organically through Windows Update. I had to install the KB4555449 Servicing Stack update first (https://www.catalog.update.microsoft.com/Search.aspx?q=KB4555449 https://www.catalog.update.microsoft.com/Search.aspx?q=KB455...), after which I was able to install the patch you linked. Did it on two machines (one freshly formatted, one old) and it took several minutes on each to install (longer than a typical update), and required a reboot after.
