After pausing the rollout of the Windows 10 October 2018 Update over the weekend, Microsoft has again begun to deliver the feature upgrade to users.

The immediate re-release was limited to Windows Insider participants, Microsoft’s opt-in beta testing program, John Cable, director of program management in the Windows servicing and delivery group, wrote in a post to a company blog. “We will carefully study the results, feedback and diagnostic data from our Insiders before taking additional steps towards re-releasing more broadly.”

Cable did not name a date when Microsoft would fully restore distribution. “Once we have confirmation that there is no further impact, we will move towards an official re-release of the Windows 10 October 2018 Update,” he said.

That form of staged delivery – where code is given first to a few, then to a larger number of users – is common among software developers, whether writ large for the launch of a major refresh or, as in this case, after a debacle and forced restart. In the latter situations, the few-then-more-then-many approach is practically mandatory to restore customer confidence.

To spur that confidence, Cable contended that Microsoft had figured out what led to users losing files after upgrading to 1809, the numerical label in the company’s yummy format. He assured users that Microsoft has everything under control.

“We have fully investigated all reports of data loss, identified and fixed all known issues in the update, and conducted internal validation,” Cable said.
