For some reason, all my pretty Excel 2007 file icons vanished. I tried reassociating by going to Control Panel > Default Programs > Set Associations and then choosing xlsx and having it always open with Excel. But the file extension icon that got associated with it is a whimpy looking icon - not what was there originally. Any idea how I can re-associate?
In the attached image, the one on the left is what the icon looks like now. I'd like to associate all xlsx files with either of the images on the right.
