Windows 11 (preview) has the same major and minor version numbers
as Windows 10: 10 and 0 respectively.
To determine if you're on Windows 10 or 11, we need to look at
the build number. As far as we can tell right now, the cutoff is build 22_000.
TODO: Narrow down this range once Win 11 is published and the last Win 10 builds
become available.
