If you use Dynamics CRM 2013 for any length of time then you will have noticed the Microsoft dialog box that pops up intermittently. It seems to occur randomly and is hard to reproduce. As far as I can see it doesn't result in any data loss so I just ignore it.
But the screen is irritating and doesn't give a good impression to first time users.
It can be disabled by logging on to CRM as the System Administrator and going to Administration and Privacy Preferences. On the Privacy Preferences dialog click the Error Reporting tab. Select "Specify the Web application error notification preferences on behalf of users" checkbox and then select the radio button "Never send an error report to Microsoft".
The errors are still happening but at least the screen isn't popping up.
