How to get Windows Version - as in "Windows 10, version 1607"?

Question

It seems that the word "version" in reference to Windows is used for different things. For example, the Windows 10 "Anniversary Update" is labeled "Version 1607" by Microsoft (here for example). But if I try to get the "Version" (on a PC with the Anniversary Update installed) using the following code, nothing is returned that looks like "1607".

// Get Version details Version ver = os.Version; Console.WriteLine("Major version: " + ver.Major); Console.WriteLine("Major Revision: " + ver.MajorRevision); Console.WriteLine("Minor version: " + ver.Minor); Console.WriteLine("Minor Revision: " + ver.MinorRevision); Console.WriteLine("Build: " + ver.Build); 

I get this:

Major version: 6 Major Revision: 0 Minor version: 2 Minor Revision: 0 Build: 9200 

How do I get the Windows 10 "version" as in "Version 1607"?

Thanks!

according to MSDN official link there's a specific version number for each windows version out there. in dot net this can be read using the Environment.OSVersion object.

Console.WriteLine("OSVersion: {0}", Environment.OSVersion); //output: OSVersion: Microsoft Windows NT 6.2.9200.0 

What you are looking for is called ReleaseID not a version of windows. this be can read from registry key:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\ReleaseId

using Microsoft.Win32;  string releaseId = Registry.GetValue(@"HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion", "ReleaseId", "").ToString(); Console.WriteLine(releaseId);
