Hi friends,

I face a problem in accessing the registry,
and creating folder in "c:\windows".

Exception:
System.Security.SecurityException: Requested registry acess is not allowed.

System.UnauthorizedAccessException: Access to the path 'c:\windows\MH\' is denied.

Code:

RegistryKey key = Registry.LocalMachine.OpenSubKey("SYSTEM\\CurrentControlSet\\Control\\Terminal Server\\WinStations\\RDP-Tcp", true);
string portNumber = key.GetValue("PortNumber").ToString();string pathWin = Environment.GetFolderPath(System.Environment.SpecialFolder.Windows);
Directory.CreateDirectory(@pathWin + @"\MHTest");

The program worka on Windows 2008, but it didn't work in windows 7.
I run the program with Administrator user.

Thanks

Sounds like the Win7 extra security layer. Even if you run through the administrator account, if the system security is at high level, it prompts for permission to avoid access to files/folders programmatically/automatically.

As you are already sure of the admin priviledges to the account used, just loosen the security of Win7. It has 4 levels as much I remeber. Allow the security to pass on wihtout prompts and see. It should work then. For now, its definitly the priviledge issue and nothing related to code.

You are right, it seems to be the logic for those.
But could you please tell me how to modify system security.
anther hint; I compared actually the permission between the both users on W2008 and W7, but they are same permission "Special Permission".
Thank you for helping :)

Sure. Try:
Control Panel -> Action Center -> Change User Account control setting -> (Pick the one that suits you. You can try 2/3/4 level)

I ran the same piece of code on Windows 7 and did not get any error. It executed fine and also created the folder. I agree with Sandeep, since my User Account Control is set to UAC never notify
