Microsoft is yet to share the date or the name of the next Windows 10 version. Codenamed Redstone 4 and known as Windows 10 Spring Creators Update in the public, Microsoft is reportedly ready to start shipping it out to the normal users. The company released Windows 10 Redstone 4 Insider Preview Build 17128 last week removing watermark and introducing no new features or changes. However, Windows maker was quick to add that this doesn’t hint at the completion of development of Windows 10 1803.

Report: Windows 10 1803 RTM build will be 17133

It appears Microsoft did finalize Windows 10 Spring Creators Update last week. Folks at WindowsCentral report that Microsoft internally signed-off on the final build of Windows 10 Redstone 4 on Friday. RTM build will be 17133, which will be the build that will be released to manufacturers and receive all the future cumulative updates that Microsoft sends throughout its support lifetime.

If the company has indeed finalized the final build, it is expected to hit the Fast Ring this week, which will be followed by Slow and Release Preview rings, as well.

Once the company is done with removing any last minute bugs and problems with the final build, the Fast ring will move on to testing Windows 10 Redstone 5 that is currently being tested by those signed up on Skip Ahead. Microsoft usually sends a cumulative update carrying all these post-RTM bug fixes alongside the official release of the feature update. The publication also said that the public rollout is likely to begin on April 10. However, considering there is no official word on this, Windows 10 1803 could arrive sooner as well.
