BUG: RegQueryInfoKey Returns Length Div 2 for cbMaxSubKeyLen

Sample Code

   #include <windows.h>
   #include <stdio.h>

   void main( int argc, char* argv[] ) {

       if (argc < 2) {
           printf("Usage: RegConnectRegistry \\\\server");
       } else {

           HKEY hRemoteKey = NULL;
           HKEY hKey = NULL;

           LONG lResult = RegConnectRegistryA( argv[1], HKEY_LOCAL_MACHINE,
               &hRemoteKey);

           if (lResult == ERROR_SUCCESS) {

               printf( "Connected to remote %s registry.\n", argv[1] );

               lResult = RegOpenKeyEx( hRemoteKey, "SOFTWARE", 0,
                   KEY_ALL_ACCESS, &hKey);

               if (lResult == ERROR_SUCCESS) {

                   DWORD cbMaxSubKeyLen;

                   printf( "Key opened.\n" );

                   lResult = RegQueryInfoKey( hKey, NULL, NULL, NULL,
                      NULL, &cbMaxSubKeyLen, NULL, NULL, NULL, NULL, NULL,
                      NULL );

                   if (lResult == ERROR_SUCCESS) {
                       printf( "The max subkey length of %s is %d.\n",
                          "HKEY_LOCAL_MACHINE\\SOFTWARE", cbMaxSubKeyLen );
                   }

                   RegCloseKey( hKey );

               } else {
                   printf( "RegOpenKey() failed.\nError: %d\n", lResult );
