如何从注册表中确定Windows Server 2016版本

Question

I have an application that determines Windows Server version. It reads version value from HKEY_LOCAL_MACHINE\\SOFTWARE\\Microsoft\\Windows NT\\CurrentVersion registry key. It works well on Windows Server 2012, Windows Server 2012 R2 and returns 6.2 and 6.3 version as expected. However on Windows Server 2016 it still returns 6.3 even though I expected it to be 10.0. Was the correct registry key moved to some different place? Should I rely on this registry entry at all? Here is a screenshot from Windows Server 2016:

I have an alternative way to use Environment.OSVersion. But I don't like it much because it requires me to specify explicitly in manifest the compatible windows versions and this means more maintenance work in the future.

Answer 1

As mentioned in the comments above, there are the CurrentMajorVersionNumber , CurrentMinorVersionNumber and CurrentBuildNumber , which all correspond to the values that Environment.OSVersion will give you.

Another way is what is described on this page: https://docs.microsoft.com/en-ca/windows/desktop/SysInfo/getting-the-system-version

To obtain the full version number for the operating system, call the GetFileVersionInfo function on one of the system DLLs, such as Kernel32.dll

That would look something like this in C#, and should work on every Windows version:

var myFileVersionInfo = FileVersionInfo.GetVersionInfo(@"C:\Windows\System32\Kernel32.dll");

Then you can use the ProductVersion property, or a combination of ProductMajorPart , ProductMinorPart and ProductBuildPart .
