Check windows version from registry c# [closed]

Question

I have a problem, How can I check the windows version from the registry in c#?

(Windows xp to windows 8.1)

Answer 1

Environment.OSVersion can give you that!

Read the MSDN documentation for Environment class to see all of the other things you can get from this class.

Answer 2

Environment.OSVersion as others stated is right way to go.

However, in case someone want to get it through registry, this can be used -

using (Microsoft.Win32.RegistryKey key = 
       Microsoft.Win32.Registry.LocalMachine
               .OpenSubKey(@"SOFTWARE\Microsoft\WindowsNT\CurrentVersion"))
{
    var osVersion = key.GetValue("CurrentVersion");
}

Registry for version is HKLM "SOFTWARE\Microsoft\Windows NT\CurrentVersion".

Also, corresponding mapping with actual OS from here -
