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.
When Microsoft releases new major versions of Windows, it has historically changed the number associated with the version. For example, Windows 7 > Windows 8 > Windows 8.1 > Windows 10.
Last week, Microsoft announced a press event on June 24 where they will "unveil the next generation of Windows."
Microsoft's Panos Panay tweeted a teaser video with this announcement showing what appeared to be sunlight streaming through a Windows logo to show a number 11.
Due to this, many thought that Microsoft might be dropping hints that the next version is Windows 11.
Regardless of the name, we know that the next major version of Windows 10 is currently codenamed 'Sun Valley .' Unlike the past few feature updates, it is a massive release with new modern features and an updated user interface.
Leaked metadata may point to a new naming scheme
When Microsoft updates their website documentation, they publish the changes on their GitHub repository.
As first reported by Windows Latest, Microsoft recently changed the HTML meta description for the public 'Windows application management' page to use the following description:
"Learn about managing applications in Windows 10 and Windows Sun Valley."

Source: Windows Latest
After realizing they mistakenly added 'Windows Sun Valley' to the page's metadata, they quickly changed the meta description to "Learn about managing applications in Windows 10."

This leak is Microsoft's first public reference to the Windows 10 Sun Valley update. However, the way it was written also indicates that Microsoft considers Windows 10 and Windows Sun Valley to be significantly different, rather than just an update to Windows 10.
It may also indicate that Microsoft is moving to a new naming scheme for the Windows operating system similar to macOS.
For example, macOS Catalina > macOS Big Sur > macOS Monterey.
While this is all speculation at this point, and we will not know for sure until the upcoming Windows event, moving to this naming scheme would make it a lot easier for Microsoft.
As they previously stated, Windows 10 is the last version of Windows, they could continue utilizing the current code base and switch to a new naming scheme.
By doing this, they would continue to validate their statement that Windows 10 is the last version.
Microsoft's continued use of Windows 10 as the codebase for Windows 10 (?) Sun Valley is also indicated by existing enablement packages that allow you to change the version number to Windows 10 build 19044, aka Windows 10 21H2 or Windows Sun Valley.

oh my god... they must be crazy... who want to remember all those names? Mac OS X bunch of names, Android bunch of names, and now Windows will add names? How does that make it easier? The number will stay anyways... nonsense.

It's the Donald Trump method. "I don't care what they are saying, as long as they are talking about me".

Give it a rest. I don't come here to read political comments and I doubt anyone else does. Sheesh. Getting back to MS's naming scheme(s), just stick with the numbering and stop trying to play catch-up with Apple; Apple envy is so unbecoming. Call it Windows 11 - period. It makes sense.

Don't really care about the name to be honest, I just want them to provide an excellent product. Windows has really gone down over the years. It's time for them to step up and bring it back up.

Just like Windows 9, I think they should call it Windows 12.

surely if this is a major rework, and they stop calling it Windows 10, if the changes are significant enough windows 10 cant be the last version (sorry - just me being picky)

It'll be interesting to see what Microsoft considers 'modern' to be. So far the majority of the 'features' added to Windows since Win 7 were pretty useless to me. About the only 'improvement' I liked was the changes they did to the task manager.
