To make the "Open File - Security Warning" "The publisher could not be verified. Are you sure you want to run this software?"

stop happening:

  1. Run gpedit.msc

  2. User Configuration/Administrative Templates/Windows Components/Attachment Manager

  3. Add "*.exe" to "Inclusion list for moderate risk file types".Other keywords:

If the file is in the list of moderate risk file types and is from the Internet zone, Windows prompts before accessing the file.  But...  it allows you to run an .exe from the Intranet zone without a prompt.
