If you’ve ever wondered why I recommend folks hold off on Windows monthly updates, permit me to introduce the latest hiccup in a whooping-cough-sized patching process.
Yesterday, Microsoft released KB 4039396, an out-of-band patch for Windows 10 Anniversary Update, version 1607. The patch brings version 1607 up to build 14393.1670. It isn’t being pushed out through Automatic Update, for reasons that should become clear. Instead, it’s available only if you know about it and install it manually, kind of a new take on the old hotfixes.
