Windows 11 has several minor feature updates coming in for 2023 and we’ve now got some glimpses of the interface changes that may be in development in the Dev Channel preview build.
According to sources familiar with the development, Microsoft designers have proposed several changes to replace the pop-up warning windows in the operating system. As you probably know, Windows pop-up windows were last revamped with Windows 8. Windows 10 or even some Windows 11 features rely on Metro-era design.
Microsoft wants to replace all remaining popups from the Windows 8 and Windows 7 era with WinUI and the modern look of Windows 11. As shown in the screenshots below, Microsoft is testing a new look for all popup warning windows in Windows 11 These pop-up windows now use WinUI and they also have rounded corners.

Of course, the buttons in the pop-up windows have also been rounded for a more modern look and it also looks better. As part of the modernization, Microsoft is deprecating solid accent themed wallpapers with more common colors, such as dark gray in dark mode or white in light mode.

In one of the proposals, Microsoft noted the need to “simplify the design” and pay more attention to small details.
Microsoft has already started testing a modern look for popups like Windows Firewall, “Rename this PC”, “Reset this PC”, etc. More boxes in the Settings app use a modern interface with support for dark themes, rounded corners, etc. The revamped “Go back to previous build” dialog also looks great on Windows 11.
Of course, the “Rename this PC” or “Reset this PC” pages are not often visited by users, but the refresh is another important step in the modernization of the operating system.
The WinUI and rounded corners seem to be the primary theme for Windows 11 and other Microsoft products. As always, a lot can change in the next few years as Windows is always evolving. In fact, according to reports, Microsoft is already considering Windows 12.
In the production versions, we’ve already seen major elements of the user interface, including the control panel, context menu, notification center, and buttons that use WinUI. It’s worth noting that Fluent Design, WinUI, and rounded corner design ideas have been floating around for the past three or four years.
Windows 11’s new major Moment Update is expected to release in February or March, and Microsoft is also reportedly working on a major feature update for Fall 2023.
