title: What is a privileged instruction?
body: <p>I have added some code which compiles cleanly and have just received this Windows error:</p>
  
  <pre><code>---------------------------
  (MonTel Administrator) 2.12.7: MtAdmin.exe - Application Error
  ---------------------------
  The exception Privileged instruction.
  
   (0xc0000096) occurred in the application at location 0x00486752.
  </code></pre>
  
  <p>I am about to go on a bug hunt, and I am expecting it to be something silly that I have done which just happens to produce this message. The code compiles cleanly with no errors or warnings. The size of the EXE file has grown to 1,454,132 bytes and includes links to <code>ODCS.lib</code>, but it is otherwise pure C to the Win32 API, with DEBUG on (running on a P4 on Windows&nbsp;2000).</p>
