There is no simple "Windows is 10 or newer" check in MSI, with the
Microsoft policy of "you don't need to know real Windows version".
See also https://developercommunity.visualstudio.com/t/detect-a-windows-version-from-msi/412198
The values that MSI sees (e.g. on my Win11) are:
Property(C): VersionNT = 603
Property(C): VersionNT64 = 603
Property(C): WindowsBuild = 9600
So those can't be used for the check. I use the WINMAJORVER that is
read from registry (Software\Microsoft\Windows NT\CurrentVersion).
There is no more need to check and install UCRT; it was dropped.
