Microsoft has confirmed that the modernized Registry Editor app recently discovered is not a new tool for Windows 11 but a sample designed to demonstrate the capabilities of Microsoft.UI.Reactor technology.67

The app, which was found in Microsoft's open-source repository, is a mockup intended for developers, not a finalized product.

Microsoft VP Scott Hanselman stated, "It’s a sample. You say it’s the new one and then in the last line of the tweet you point out it’s a sample," emphasizing the app's purpose. Windows Insider lead Marcus Ash echoed this, confirming it is "not a developer preview of a new regedit."5

While the modernized Registry Editor showcases a more contemporary interface using WinUI 3, it remains unfinished and lacks essential features such as saving favorites, traditional .reg file import/export, and a functional permissions menu.

Despite these limitations, there are indications that a modern Registry Editor is planned for the future, although it is not currently slated for release with Windows 11.

The existing Registry Editor has seen little change since Windows 95, and the new version retains its two-panel layout while updating the interface with modern controls and Windows 11's Mica background effect.910

Microsoft has not announced any plans to integrate this sample into Windows 11, leaving its future uncertain.11

Key Insight
“The sample app, built with WinUI 3 and Microsoft.UI.Reactor, supports creating, renaming, and deleting registry keys on Windows 11 build 26340.9882, but lacks Favorites, .reg import/export, and permissions. Microsoft VP Scott Hanselman and Windows Insider lead Marcus Ash both emphasized on X that it's "a sample" and not a developer preview.”
