How to read "company name" from Windows using C #?

Question

Some programs read the company name that you entered when installing Windows and displayed it in the program. How it's done? Do they just read the name from the registry?

Answer 1

If you want the registered name of the company to be entered in the register, you can get it from:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\RegisteredOrganization

Using the registry class, you can do something in this direction:

string org = (string)Microsoft.Win32.Registry.GetValue(@"HKEY_LOCAL_MACHINE\Software\Microsoft\Windows NT\CurrentVersion", "RegisteredOrganization", "");

Answer 2

You can read it. Using WMI, it looks like you are after the Win32_OperatingSystem class, and the Organization element of this class contains the company name.

        static void Main(string[] args)
        {
            ManagementClass c = new ManagementClass("Win32_OperatingSystem");

            foreach (ManagementObject o in c.GetInstances())
            {
                Console.WriteLine("Registered User: {0}, Organization: {1}", o["RegisteredUser"], o["Organization"]);
            }
            Console.WriteLine("Finis!");
            Console.ReadKey();
        }
    }
}

using Microsoft.Win32;

namespace Extensions
{
    public static class MyExtensions
    {
        public static string CompanyName(this RegistryKey key)
        {
            // this string goes in my resources file usually
            return (string)key.OpenSubKey("SOFTWARE\\Microsoft\\Windows NT\\CurrentVersion").GetValue("RegisteredOrganization");
        }
    }
}

:

RegistryKey key = Registry.LocalMachine;
return key.CompanyName();

Nothing out of the ordinary, just a prettier way to deal with deleted registry values.
