I am using newly installed Window 7 Professional version 6.1. I want to click some files link on web and need to specify & open them in Excel. As such, I need to edit the file type tab in Folder option in order to click & open the file by default in Excel program. However, I did not find the tab to do editing. Is there any other ways to change this settings or I have missed some components during setup to make said tab available ?
