Microsoft is finalizing the Windows 10 Fall Creators Update (FCU) ahead of its launch on October 17. Over the last month, the company has been sending out previews on the Insider, but they have lacked new features. Microsoft is also focusing on its Skip Ahead feature on the Insider with a new update.

Specifically, the company is sending out Windows Preview Build 17004 for PC today. If you are unfamiliar with Skip Ahead, it was launched in July and added a new branch to the Windows Insider Program.

It allows users to jump forward to build ahead of the next Windows 10 release. At this moment, that means Insiders on Skip Ahead can preview Redstone 4. Microsoft is currently developing Redstone 3, which most people know as the Fall Creators Update.

Previously on the Insider Program, members could only preview the next build (Redstone 3). With Skip Ahead, they can move to the next branch for the first time. It also means Microsoft is juggling two different branches in preview.

Of course, the company is used to developing two unreleased branches at the same time. As FCU is close to being released to the public, Redstone 4 is arguably more exciting right now. FCU is not getting new features, so Redstone 4 is where it is at for new Windows 10 goodies.

Incidentally, Microsoft has yet to official announce Redstone 4. We expect the company will fully announce the release and its official name sometime during the fall.
