1. Click Start -> Run -> Type gpedit.msc and click ok.
2. Go to User Configuration >> Administrative Templates >> Windows Components >> Attachment Manager
3. Open the Inclusion list for moderate risk file types setting.
4. Set the policy to Enabled, then add “*.exe;” or whatever the file extension you are using to the Specify high risk extensions box. This will stop the popup for any more programs.
