Hi Alan, I agree it is a pity that the minor version (dwMinorVersion) was not increased .
Looking at the build number was not my preferred way to handle this .
My understanding (checked with our internal SAP-MS porting guys) is that the buildNumber of Windows server 2016 will not get larger than
the minimum introduced buildNumber of Windows server 2019 .
Best regards, Matthias
