Microsoft’s Windows 10 patching pace is so fast at this point that one Patch Tuesday doesn’t cover all the bases. Instead, we’re seeing one massive Cumulative Update on Patch Tuesday, and a second — typically large — grab bag of patches later in the month.
You have to wonder what’s happening, though, when Microsoft can deliver its second bundle of patches for 1709, 1703 and 1607 before the second patch for the latest version, 1803, sees light of day.
