Sometimes we may be interested to remove or disable PowerPoint add-ins that were previously installed. We can do this in powerpoint 2010 by entering powerpoint options and then opening the powerpoint add-in tab.
Open powerpoint and then choose File -> Options to enter the Options Window. You will see a window like this one:
Here you can control what powerpoint add-ins are installed and manage the addins by clicking Go button. Make sure you choose COM Add-ins, powerpoint Add-ins, Actions or Disabled Items to manage the proper addins. This can be very convenient for example if we need to remove unused addins from powerpoint to fix performance issues or powerpoint not responding problem.
In this window we can filter by active, inactive addins, document related addins and disabled items.
