In advance of Microsoft's June 24 Windows event, an unfinished build of Windows 11, or at least the next version of Windows, has leaked onto the Internet, and some people seem to be taking it personally.

Public backlash against new ideas and products is as common as a mosquito in the summer, and it stings just as much. This time, however, it may be significant enough to affect the course of Microsoft's next big Windows release.

If you haven't seen it yet, a leaked development build of Windows that spread across the Internet in mid-June reveals a streamlined new look for the venerable operating system, with rounded corners and a centered Start button.

These two new changes alone seem to have angered many people and may affect Microsoft's messaging, pushing the company to offer more visual customization options in the final build.

For example, some people feel that the rounded edges of Windows' new UI are a bit too similar to those found in Apple's macOS. The fact that the Start button is centered, even though it could be moved back to the left corner of the taskbar, also causes confusion.

There has also been some concern online about the leaked new Windows build, which is optimized for touchscreens and closely resembles the promotional shots of Windows 10X to compete with Chrome OS.

Announced simultaneously with the Surface Neo (a dual-screen laptop that was never released) in 2019, Windows 10X was initially a touch-first version of Windows 10 redesigned from the ground up for easier use and better security It was touted as a "touch-first" version of Windows 10 that was to be released at the same time as Neo, but reports earlier this year suggested that the OS was first delayed and then caught up in a broader redesign of Microsoft's core Windows products.

With the release of the leaked Windows build and the Windows press event just around the corner, these reports appear to be true. Many fans seem more than a little dismayed that the next big thing for Windows appears to be a subtle redesign that offers a mishmash of small changes rather than a major overhaul of the aging operating system. [Of course, the leaked build is unfinished and of questionable provenance. It is possible that Microsoft has significantly overhauled Windows in ways that are not apparent in that build. But we will have to wait until the company holds its Windows press event on Thursday, June 24 at 11 a.m. ET.
