title: Batch to force close all excel files
body: <p>Is it possible to create a batch that forces all running instances of excel to close without saving any changes?</p>
  
  <p>I ask because we have several <code>VB.net</code> programs and <code>VBA</code> programs that occasionally leave excel open (invisibly) when they error and these instances can interfere with future procedures and slow down performance.</p>
