Cody Kloepfel - I have not seen this issue as per the blog 

In Windows 10 device, Lunch Internet Explorer, you see Prevents Internet Explorer launching. In addition, a prompt will appear with the message based on the above configuration, “The action is restricted. For more information, please contact your system administrator”.

When the user clicks on OK, It will automatically redirect to Microsoft Edge Browser, and users have the following experience –

• The IE11 icon on the Start Menu will be removed, the taskbar icon will remain.
• When users try to launch shortcuts or file associations that use IE11, they will be redirected to open the same file/URL in Microsoft Edge.
• When users try to launch IE11 by directly invoking the iexplore.exe binary, Microsoft Edge will launch instead.
