Zotero will automatically offer to import RIS files served from certain websites. You can disable that in the Zotero Connector preferences — right-click on the save button to access the preferences.
For files you've downloaded (which would include those not served properly by websites, such that Zotero can't detect them automatically) that's just a Windows setting. We can't help with that, but you'd change the default program as you would for any other file type.
