I am having the exact same issue. my problems occurred when installing the latest CU21 update to exchange 2013.
w3wvc is stuck in a stopping state and IIS GUI freezes when I try to use it.
One other thing I noticed is that the RPC service shows "running" but all options to start, restart, or stop are greyed out.
