As of today we are just two weeks away from the global availability of the fourth major feature update for Windows 10 - the Fall Creators Update - which will begin its rollout on 17 October 2017 as announced by Microsoft in early September at IFA 2017.

Overnight an update to Redstone 3 Build 16299 was released that moves the Windows Insider Fast Ring to Build 16299.15 - the first Cumulative Update for Redstone 3 as noted by Windows Insider Chief Dona Sarkar on the Build 16299 Release Notes page:

"UPDATE 10/2: We have released Windows 10 Insider Preview Build 16299.15 to Windows Insiders in the Fast ring. As we prepare to release the Windows 10 Fall Creators Update to the world on October 17th, we will now start testing out servicing this build with the Cumulative Updates via Windows Update."

Although this was a Cumulative Update to Build 16299, it is a full build download versus the smaller format of a Cumulative Update. According to Brandon LeBlanc on Twitter, this update is essentially the same as the release of 16299 that went to Fast and Slow Ring last week except the desktop watermark has been removed.

I have also confirmed that the build expiration date, aka time bomb, is no longer part of this release either.

The move to Cumulative Updates is right inline with what Microsoft did with the Creators Update a couple of weeks prior to its release back in April. It also reveals that the final build of the Fall Creators Update will be 16299.XXX and that minor build number part will be dictated by any subsequent Cumulative Updates that are pushed out for the operating system.

Next up on the build shuffle for the Fall Creators Update should be seeing Build 16299.15 move into Slow Ring and then subsequently into the Release Preview Ring. If there is another Cumulative Update released then that will start the process over again although Microsoft could choose to just release a Cumulative Update on 17 October when the update becomes globally available as a Day One patch. This would not be the first time the company has done that for a feature update release.

No matter what happens from here on, the Fall Creators Update is effectively complete and just binding its time until the rollout begins in two weeks.

I have opted to move two more of my physical devices to Build 16299.15 for a total of three running this build on bare metal. When this build moves to Release Preview that is likely when my two main desktop devices will make the shift to the Fall Creators Update.

So how are you approaching the final release on your systems?
