Problem with KEY_VALUE_BASIC_INFORMATION in CmRegisterCallback.
Hi, I want to hide in registry name of key value. I write driver, that using CmRegisterCallback. But I can't catch name of key value that I need. When I DbgPrint PKEY_VALUE_BASIC_INFORMATION->Name I get only symbols [ , u . Where is my mistake? Can anybody help me?My RegistryCallback source:

NTSTATUS RegistryCallback(PVOID CallbackContext, PVOID Argument1, PVOID Argument2)
{
	PDEVICE_CONTEXT pContext = (PDEVICE_CONTEXT) CallbackContext;
	REG_NOTIFY_CLASS Action  = (REG_NOTIFY_CLASS) Argument1;
    UNICODE_STRING regKeyNameValueToHide = {0}; 
   
    try
    {
	switch (Action) 
	{ 
	 
    case RegNtEnumerateValueKey:
		{
		    PREG_ENUMERATE_VALUE_KEY_INFORMATION pInfo = (PREG_ENUMERATE_VALUE_KEY_INFORMATION) Argument2;
		    //DbgPrint(pInfo->ValueName->Buffer);
		    RtlInitUnicodeString(®KeyNameValueToHide,L"alex-56328943333");
			
			if(pInfo->KeyValueInformationClass == KeyValueBasicInformation)
			{
			   PKEY_VALUE_BASIC_INFORMATION  pKeyValueBasicInfirmation = (PKEY_VALUE_BASIC_INFORMATION) pInfo->KeyValueInformation;
			   UNICODE_STRING regKeyNameValue = {0};
			   RtlInitUnicodeString(®KeyNameValue,pKeyValueBasicInfirmation->Name);
			    
			   if (RtlEqualUnicodeString(®KeyNameValue, ®KeyNameValueToHide, 1))
			   {  
				   return STATUS_CALLBACK_BYPASS;
			   } 
			}
			else if(pInfo->KeyValueInformationClass == KeyValueFullInformation)
			{
			   PKEY_VALUE_FULL_INFORMATION  pKeyValueFullInfirmation = (PKEY_VALUE_FULL_INFORMATION) pInfo->KeyValueInformation;
			   UNICODE_STRING regKeyNameValue = {0};
			   RtlInitUnicodeString(®KeyNameValue,pKeyValueFullInfirmation->Name); 
			    if (RtlEqualUnicodeString(®KeyNameValue, ®KeyNameValueToHide, 1))
			   {    
				   return STATUS_CALLBACK_BYPASS;
			   }
			}
		   
		   break;
	    }  
	default:
		{
			 
			return STATUS_SUCCESS  
			break;
		}
		
	}

	}
	except (EXCEPTION_EXECUTE_HANDLER)
   {
     DbgPrint("Exception in RegistryCallback!!!");
   }
	return STATUS_SUCCESS;
}
