Windows 10X leaks: Hands-on with Microsoft's new, simplified OS Microsoft's new Windows 10X continues to look somewhat boring, but that's okay. Microsoft’s Windows 10X has leaked, and it’s boring. Well, it’s designed to be boring. Simple, really—uncomplicated, straightforward, without the fuss and clutter of “traditional” Windows. We wrote last year that Windows 10X now appears to be the new Windows 10 S (Windows 10 in S Mode); after spending some hands-on time with the leaked build, we believe those impressions have been confirmed. We’d like to say that Windows 10X has been graphically overhauled, with a variety of new features. However, the fact is that if you read our early Windows 10X coverage a year ago—when Microsoft was visualizing Windows 10X as the future of dual-screen devices—little has changed. (Here’s our original Windows 10X hands-on video for reference.) Well, there’s been one major tweak, of course: Windows 10X is now designed for single-screen PCs.
