  We present the theoretical basis and sample Monte Carlo data for the YFS
exponentiated calculation of $e^+e^- \rightarrow W^+ W^- \rightarrow f_1\bar
f'_1 + \bar f_2 f'_2$ at and beyond LEP2 energies, where the left-handed parts
of $f_i$ and $f'_i$ are the respective upper and lower components of an
$SU_{2L}$ doublet, $i=1,2$. The problem of gauge invariance of the radiation
from the unstable charged spin~1 $W^{\pm}$ is solved in an entirely physical
manner. Our formulas are illustrated in a proto-typical YFS Monte Carlo event
generator YFSWW2, wherein both Standard Model and anomalous triple gauge boson
couplings are allowed.
