Int DesiredAccess, // desired access to process System.IntPtr ProcessHandle, // handle to process

[DllImport('advapi32', SetLastError = true), PInvoke stuff required to set/enable security privileges MboShutdown = manObj.InvokeMethod('Win32Shutdown', Flag 1 means we want to shut down the systemДЇoreach (ManagementObject manObj in mcWin32.GetInstances()) ManagementBaseObject mboShutdownParams = mcWin32.GetMethodParameters('Win32Shutdown') You can't shutdown without security privileges If (!TokenAdjuster.EnablePrivilege('SeShutdownPrivilege', true))Д¬onsole.WriteLine('Could not enable SeShutdownPrivilege') Д¬onsole.WriteLine('Enabled SeShutdownPrivilege') ManagementClass mcWin32 = new ManagementClass('Win32_OperatingSystem') I've pasted my basic use of his solution below in case that link gets old. I found the answer at written by a guy called Richard Hill. The solution was for the process to request the privilege for itself. I had trouble trying to use the WMI method accepted above because i always got privilige not held exceptions despite running the program as an administrator.

In production code you should be checking the return values of the API calls, but I left that out to make the example clearer.
