Microsoft may have mistakenly leaked that the upcoming next generation of Windows 10 will move away from its current naming scheme and switch to a macOS scheme using geographic locations or development names. Microsoft recently changed the HTML meta description for the public ‘Windows application management’ page to “Learn about managing applications in Windows 10 and Windows Sun Valley”” Microsoft may also indicate that Microsoft is moving to a new naming scheme for the Windows operating system similar to Apple’s MacOS Catalina and Monterey. Microsoft announced a press event on June 24 where they will “”unveil the next generation”” of Windows.”
