Microsoft, like most companies, don't use the internal implementation as part of the name brand. It was called "Windows" long before it got the current kernel.

Microsoft, like most companies, don't use the internal implementation as part of the name brand. It was called "Windows" long before it got the current kernel. ("Edge" is switching engines, too, but not names.) I see no reason they'd change the Windows name even if they decided to switch out the kernel.
