Microsoft Releases Windows 10 Build 17738 for Redstone 5

Microsoft is winding down Redstone 5 preparations ahead of the new Windows 10 version arriving in October. Build 17738 focuses on stabilization.


Users running the Windows Insider Program are getting a new Windows 10 preview build today. Microsoft has rolled out a new release on the Redstone 5 (RS5) branch. With this update, the preview of Windows 10 is bumped to version 17738, following version 17735 that was released a week ago.

Redstone 5 is expected to launch in October, so we are approaching the final straight of previews. Microsoft will likely send the finalized RTM (release to manufacturing) build during September. Considering the naming pattern, the company took with the April 2018 Update, we expect RS5 to become the October 2018 Update.

For the most part, Microsoft is now down to stabilizing Redstone 5 ahead of launch. New features are not frequent on the Inside these days. Instead, the company is fixing known problems and improving current services.

That’s where we sit with Windows 10 Preview build 17738, which focuses on those areas. It is also worth noting that Microsoft is also preparing the 19H1 branch of Windows 10 for a spring 2019 release. On the Insider this branch is running on the Skip Ahead section and is not part of build 17738.
