Registry::Users Field

Contains information about the default user configuration. This field reads the Windows registry base key HKEY_USERS.

Namespace:  Microsoft.Win32
Assembly:  mscorlib (in mscorlib.dll)

static initonly RegistryKey^ Users

This key contains a branch for each user of the computer. The default configuration is supplied for new users on the local computer and for the default current user if the user has not changed preferences. Because Windows 98/ME also supports Registry.Users, applications can access the user-specific information the same way they do under Windows 2000. Each user's information is stored in a separate file, which can be stored locally or on a network server. Windows 98/ME can copy this file to the user's current system so that settings can move from one computer to another with the user.

The following example demonstrates how to retrieve the subkeys of this key, and prints their names to the screen. Use the OpenSubKey method to create an instance of the particular subkey of interest. You can then use other operations in RegistryKey to manipulate that key.

using namespace System;
using namespace Microsoft::Win32;
void PrintKeys( RegistryKey ^ rkey )

   // Retrieve all the subkeys for the specified key.
   array<String^>^names = rkey->GetSubKeyNames();
   int icount = 0;
   Console::WriteLine( "Subkeys of {0}", rkey->Name );
   Console::WriteLine( "-----------------------------------------------" );

   // Print the contents of the array to the console.
   System::Collections::IEnumerator^ enum0 = names->GetEnumerator();
   while ( enum0->MoveNext() )
      String^ s = safe_cast<String^>(enum0->Current);
      Console::WriteLine( s );

      // The following code puts a limit on the number
      // of keys displayed.  Comment it out to print the
      // complete list.
      if ( icount >= 10 )

int main()

   // Create a RegistryKey, which will access the HKEY_USERS
   // key in the registry of this machine.
   RegistryKey ^ rk = Registry::Users;

   // Print out the keys.
   PrintKeys( rk );
