How-To Geek reports the "August Update" (Windows 8.1 Update 2) was released on 12 August 2014, squarely inside the pin's stored 11-13 August window, though the piece notes the update was minor enough that "you probably didn't even notice."
The Register, published 5 August 2014, reports Microsoft scrapping a standalone Windows 8.1 Update 2 in favor of folding minor fixes into the 12 August Update Tuesday cycle, a date matching the pin's stored window even as the article complicates the pin's framing of it as a discrete "Update 2."
Something missing or wrong? Say it in your own words: a link that backs this pin up, a different start or end date and why, or a fact it lacks or gets wrong. The AI checks it against this pin's sources, searches for better ones, and adds any page that backs you up. The pin's own sources still count most. A picture that shows something else, or shows it badly, is looked at too, and moved down or replaced.
