I've had to correct views I've inherited that used select * and returned many unneeded columns. A quick and dirty way to correct them is to right click a view, select Open, select the 'show sql pane' button in the toolbar, and add to the displayed query WHERE 1=0 (or something of the like). I click the exclamation point and the resulting sql query string now explicitly shows all columns. You can now copy this and alter your view in a normal ssms window. It is a time saver when the view returns tens of columns.
