Is the Windows October 2018 update here again? Or did it never exist previously? Are we all in a feverish dream where the latest version, build 1809, is stable and fit for purpose, and Patch Tuesday was totally uneventful? Our finger hovers over the "no" button, but we live in hope of someone one day fitted a "yes" key.

In early October, Microsoft made Windows 10, Windows Server, and Windows Server 2019 build 1809 available for download, and within days pulled them after all kinds of terrible shenanigans started happening, primarily people’s files going AWOL.
