Uso de WUA de forma remota con C#

Question

Estoy intentando conectarme a una máquina remota y determinar si hay alguna actualización de Windows para instalar utilizando C# y WUApiLib. Parece bastante sencillo, sin embargo, no puedo encontrar la forma de conectarme realmente a la computadora remota.

http://msdn.microsoft.com/en-us/library/aa387288(v=VS.85).aspx identifica que se puede utilizar de forma remota, con algunas excepciones que no me preocupan, pero parece que no hay documentación sobre cómo realmente conectarse. Traté de pasar el nombre de una computadora, pero esto no funcionó tan bien (pasar un nombre que contiene galimatías "tiene éxito" al igual que no pasar nada, y da como resultado los mismos recuentos así que asumo que la cadena no se usa.)

var updateSession = new UpdateSession(dependencies.ComputerName); 
var searcher = updateSession.CreateUpdateSearcher(); 
var results = searcher.Search("IsInstalled=0 and Type='Software'"); 

¿Alguien sabe quién utiliza WUA de forma remota a través de C#?

Estaba buscando lo mismo hace años y escribí un pequeño guión.

Answer 2

Prueba esto:

Type t = Type.GetTypeFromProgID("Microsoft.Update.Session", HOSTNAME); 
UpdateSession uSession = (UpdateSession)Activator.CreateInstance(t); 

IUpdateSearcher uSearcher = uSession.CreateUpdateSearcher(); 
uSearcher.ServerSelection = ServerSelection.ssWindowsUpdate; 
uSearcher.IncludePotentiallySupersededUpdates = false; 
uSearcher.Online = false; 

ISearchResult sResult = uSearcher.Search(
    "IsInstalled=0 And IsHidden=0 And Type='Software'"); 

Answer 3

 Type t = Type.GetTypeFromProgID("Microsoft.Update.Session", "SYDEMMTA001"); 
     UpdateSession session = (UpdateSession)Activator.CreateInstance(t); 
     IUpdateSearcher updateSearcher = session.CreateUpdateSearcher(); 
     //int count = updateSearcher.GetTotalHistoryCount(); 
     //IUpdateHistoryEntryCollection history = updateSearcher.QueryHistory(0, count); 
     //for (int i = 0; i < count; ++i) 
     //{ 
     // Console.WriteLine(string.Format("Title: {0}\tSupportURL: {1}\tDate: {2}\tResult Code: {3}\tDescription: {4}\r\n", history[i].Title, history[i].SupportUrl, history[i].Date, history[i].ResultCode, history[i].Description)); 
     //} 
     //Console.WriteLine("Total up: {0}", count); 
     ISearchResult sResult = updateSearcher.Search("IsInstalled=0 AND IsPresent=0"); 
     foreach (IUpdate x in sResult.Updates) 
     { 
      Console.WriteLine(x.Title); 
     }
