Per my sources, Microsoft will be releasing the Windows 10 Creators Update this April. While the update initially had a version number of 1703 in Insider Builds leading to speculation that it would be released in March 2017, we can reveal that the final version number will actually be 1704 for an April release. This is not the first time that Microsoft has changed version numbers in Insider Preview releases, the firm previously changed the Xbox’s Anniversary Update release number from 1607 to 1608 last year.
