As we can add any programs to our right click menu on windows by modifying the registry.
Is there any way to add an option to keep a window always on top by utilizing the title bar right click menu without using any third party software such as AHK, deskpins, etc?

No.
Using additional software you might be able to make this work but there will still be programs that won't support it. For examples see Make any windowed application 'Always On Top' without keyboard shortcut?.

it's possible do make a window on top with VBS or PowerShell, but they can't add to the application context menu like that
