Half of Windows 10 users are already on the latest build. The rest should follow soon.

Some four months after its initial release, Microsoft says it has opened the floodgates and is now pushing out Windows 10 version 1703, the Creators Update, to every compatible PC (a category that excludes systems using Intel's Clover Trail Atoms).

Earlier this month, AdDuplex, which tracks the penetration of the different Windows 10 versions, reported that as of July 18, the Creators Update had just passed 50 percent of Windows 10 systems. Forty-six percent are on the previous version, 1607 (aka the Anniversary Update).

Until now, the deployment of the Creators Update has been throttled to stage its rollout. That throttle is now removed, so most of that 46 percent should now start upgrading. Microsoft is also saying that with this full rollout, enterprise customers should have confidence deploying the update. With Microsoft getting rid of the "Current Branch" and "Current Branch for Business" nomenclature, this is the closest thing to a signal that the version is enterprise-ready.

The remaining 3.9 percent of Windows 10 users are divided 0.4 percent on an Insider build, 0.9 percent on the initial release, version 1507, and 2.6 percent on the first major update, version 1511 (aka the November Update). Those users on version 1507 should have already upgraded, since their build last received a security update on May 9th this year. The company today announced the end-of-support for version 1511: this build will receive its final update on October 10, 2017.
