MS: Always ask before opening this type of file

When you open a link or URL for a file in Internet Explorer (IE) or any browser like FireFox, you will receive this dialog:


File Download

Do you want to open or save this file?

Three buttons: Open - Save - Cancel

And one checkbox Always ask before opening this type of file

The solution is add (or modify existing) registry key to the machine (you can use a GPO to update several machines)
