I do not include the Windows Defender definition updates since these have been taken out of Windows Update as far as I can tell and are now a part of Windows Defender itself, which I strongly prefer.
Windows Defender definition updates do not change either the Windows 10 OS or the Windows Defender software so they are not, in any meaningful sense, a Windows Update.
My last Windows Defender definition update shows yesterday's date. I am running Win10 Home, 64-bit, Version 1703, Build 15063.540
My last attempted Windows Update install was on 8/15/2017, and my last Windows Update check for updates was today (9/1/2017) at 12:16 AM.
P.S.: Just checked my partner's machine, running the same version/build, and his last update was on 8/8/2017, and last check for Windows Updates was at 9:31 AM this morning. I have little doubt that I would find something similar were I to check my Win10 Pro, 32-bit, desktop downstairs as well.

. . . the presumption of innocence, while essential in the legal realm, does not mean the elimination of common sense outside it. The willing suspension of disbelief has its limits, or should.
