title: Disable macro in open workbook
body: <p>Sometimes when I open a workbook, Excel asks me if I want to enable content and macros. At this time I have the choice not to enable macros or not.</p>
  
  <p>But sometimes Excel considers a workbook trusted and I don't get this question. In these cases, when a workbook has been opened and macros have been enabled automatically, is there any way for me to disable macros in the workbook that is already open and running with macros?</p>
