Microsoft is expected to release its next version of Windows 10 in the coming weeks. Known as the Windows 10 October 2018 Update, reports suggest that this release could happen as early as October 2. The date isn’t unlikely since Microsoft likes to deliver updates on Tuesdays and since we haven’t seen new Preview Builds in the last few days, it is fair to assume that the development process has ended.

According to a report by the folks at WindowsCentral, the development on the Windows 10 Redstone 5 “is now complete,” citing insider sources. “Microsoft has internally signed-off on the RTM (Release To Manufacturing) build of Redstone 5 at 17763 (details here), which is build that has been in testing with Insiders for more than a week on PC, HoloLens, and Xbox,” the report suggests.
