With only a couple of days remaining before CES 2017 kicks off, and not much happening with Insider Previews since the middle of December, aside from a Cumulative Update, we've had to make do with a Christmas day leak of build 14997, which in itself brought some new features.
Now, if the above tweet is to be believed, the first builds above 15000 have started to make their way online, or at the very least, teased. Although it's unclear where the image is from, it does show Version 10.0.15003, which is the Creators Update, and possibly what will be shown off at CES due to the apparent use of the logo in the tweet.
On the second line of the image "Todos los derechos reservados." is shown, which means "All rights reserved." in Spanish, indicating the build is from a Spanish language partner.
According to a recent report, the Windows 10 Creators Update, which will be called version 1704 (for 2017 and April) will be "feature-locked" by mid- to late-January with a target release date of April, contrary to the earlier reports of a possible March roll-out.
In any case, it's unclear where this image is from, so until it actually leaks online or Microsoft teases it itself, take this with a grain of salt.
Update, and now the original tweet has been pulled, with the account contacting Neowin to say it is fake. Either way, what we do know is that: builds are approaching 15000, and are already over it internally at Microsoft. We won't see an Insider build today, but with any luck the next one will be in the 15000's.
