how to use WMI to get registry keys

  the second.
  
  So in your opinion there are no advantages of using WMI in this situation (by the way, i have admin privileges on the remote machine)

  sorry, which link is this for the first or second

  I think you could still use the .NET way of accessing a remote registry key, again, security permissions will be an issue. I'll see what I can dig up

  it depends on permission really, and authentication. If you give it the correct credentials either using the .NET Classes, or WMI, then it will work AFAIK. its better to go through the .NET Route as its cheaper and faster than invoking WMI.

  well, one thing i didn't mentioned was that the registry i want to access is on a remote machine, that's why i want to use WMI.

  why dont you use the Microsoft.Win32 namespace to access the registry Easier and faster than WMI Either way you may still have security issues.

  I've been trying to understand the VB code but i don't know how can i execute methods from providers using C# and the fact that the StdRegProv Requires Stdprov.dll is also a problem because i don't know where to find it. :\
  
  Can you show me some sort of example in C#

  //const uint CLASSES_ROOT = 0x80000000;
  //const uint CURRENT_USER = 0x80000001;
  //const uint USERS = 0x80000003;
  //const uint CURRENT_CONFIG = 0x80000005;
  const uint LOCAL_MACHINE = 0x80000002;
  
  ConnectionOptions options = new ConnectionOptions();
  options.Impersonation = ImpersonationLevel.Impersonate;
  options.EnablePrivileges = true;
  
  options.Password = password; //null if u want to access the local machine
  options.Username = user; //null if u want to access the local machine
  
  
  ManagementScope myScope = new ManagementScope("\\\\" + host + "\\root\\default", options);
  ManagementPath mypath = new ManagementPath("StdRegProv");
  ManagementClass mc = new ManagementClass(myScope, mypath, null);
  
  ManagementBaseObject inParams = mc.GetMethodParameters("GetStringValue");
  inParams["hDefKey"] = LOCAL_MACHINE;
  inParams["sSubKeyName"] = "SOFTWARE\\Microsoft\\Windows\\CurrentVersion";
  inParams["sValueName"] = "ProgramFilesDir";
  
  ManagementBaseObject outParams = mc.InvokeMethod("GetStringValue", inParams, null);
  
  if (Convert.ToUInt32(outParams["ReturnValue"]) == 0)
  {
  programFilesPath = outParams["sValue"].ToString();
  }
  else
  {
  programFilesPath = "N/A";
  }
  
  Console.WriteLine("%ProgramFiles% - " + programFilesPath);
