Windows is stand alone, so you'll need to do the SP on both.
with SQL, because the DB Engine is shared between the nodes, when you
install the SQL SP it dumps the updated files on all of your nodes.
But because there are parts that are not part of the cluster (such as ssis,
client tools etc) you need to run the SP on all nodes to update those none
clustered parts...
if all you have is the DB Engine then you only need to run the SP on the
active node.
