The "official" release of the Windows 10 Creators Update, version 1703, won't come until Patch Tuesday on April 11, but if you want to upgrade now—and don't want to enroll your system in the potentially unstable Windows Insider Program—you can now do so.

The Windows 10 Update Assistant will upgrade any Windows 10 Home or Pro system to the Creators Update; you'll need to grab the latest version of the Assistant and then run it, but it should be straightforward enough. If you're upgrading more than one machine or want to perform a clean install, the Media Creation Tool, available from the same link, is the better bet; the Media Creation Tool can fetch an ISO to burn a DVD or create a bootable USB drive, and that can be used for bare metal installs.

The Creators Update itself is build 15063.0, but there will be a small Cumulative Update delivered on April 11. Previews of this patch have been rolled out to insiders, with the fast ring Insiders on 15063.14 and slow ring Insiders on 15063.13. Using the Update Assistant or Media Creation Tool appears to also update to 15063.13. This situation may well change by the actual release day next week.

If you're already in the Insider Program and want to get off that train, now is a good time to do so. If you elect to stop receiving Insider builds in the Windows Insider Program section of the Settings app, you'll be asked if Windows should "Keep giving me builds until the next Windows release." Pick that option and you'll continue to receive the previews of Cumulative Updates until Tuesday, at which point your system will revert to only receiving the stable updates. This is a handy way of making sure you don't accidentally overshoot and receive a post-Creators Update build.

New builds of the next major update, likely to land in about six months, will soon be shipping. As has been the pattern in the past, the initial Insider builds won't include much in the way of new functionality, with Microsoft instead using them to continue refining its engineering processes to handle development of the OneCore unified Windows platform and the migration to Git source control.
