What do you want to do with it? From this answer, it will depend the connection(s) you will do.

Do you want the voltage of only one winding rectified but more current than one winding can give? Are the voltages of all four secondary windings the same?

How much single DC voltage do you need? If it's low and you don't want use huge regulator's heatsink you could also rewiring both secondaries up to a desired AC voltage output, and then use them as a single supply ignoring the O volt connection.
