I pushed out an .exe this morning to all desktops, network wide, and received numerous complaints that when users tried to run the .exe, a popup would prompt for comfirmation before allowing it to run. Its title was:
“Open File – Security Warning”
Of course, there is a checkbox to keep this prompt from reapearing, but we all know how end users can be…
So the ‘quick fix’ is to create or edit a group policy object and under “User Configuration > Administrative Templates > Windows Components > Attachment Manager”, enable “Inclusion list for low file types” and add .exe with the leading period.
After a gpupdate, the security prompt no longer came up.
