According to Zac Bowden of Windows Central, these images, shared by Twitter user @NTAuthority, come from Windows 10 build 18947, a Canary build, not yet tested internally by Microsoft. However, it was pushed to all 32-bit Windows 10 Insider Preview Build testers, even those on the slow ring cycle, which is supposed to be where you get the more stable updates.
