Here's the update: https://support.microsoft.com/en-gb/kb/3035583 https://support.microsoft.com/en-gb/kb/3035583 ...that explains the Windows 10 update, but on my machine it just says "Install this update to resolve issues in Windows. blah blah blah" which is the same boilerplate they all use. The update size is uniquely given as a range 722 KB - 821 KB, which is probably a low estimate for an OS installer. So, no indication of the magnitude of this. Since it isn't a security update, anyone with a properly-configured system (IMO) shouldn't be bothered by it. Unless Microsoft updates it to a "security update". Which seems possible. The whole "auto update and restart" thing seemed like a potentially global-scale Therac-25 style bad idea when I first heard about it on Windows XP (or whenever). But it never happened--I guess not too many critical systems use Windows. Just millions of people losing millions of hours of productivity...
