Solution 1

1. Run gpedit.msc


2. Go to User Configuration >> Administrative Templates >>Windows Components >> Attachment Manager


3. Add *.exe to the Inclusion list for moderate risk filetypes setting.


This policy setting allows you to configure the list ofmoderate risk file types. If the attachment is in the list ofmoderate risk file types and is from the restricted orInternet zone, Windows prompts the user beforeaccessing the file.... In other words, this allows you to run an .exe from theIntranet zone without a prompt, but it will warn beforerunning one from the Internet.
