  We realize, by Monte Carlo event generator methods, the exact O}(\alpha)$ YFS
exponentiated calculation of $e^+e^- \to W^+ W^- (\to f_1\bar f'_1 + \bar f_2
f'_2)$ 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,
$i=1,2$. Our calculation is gauge invariant from the standpoint of its
radiative effects and the respective YFS Monte Carlo event generator YFSWW3,
wherein both Standard Model and anomalous triple gauge boson couplings are
allowed, generates $n(\gamma)$ radiation both from the initial state and from
the final $W^+ W^-$. Sample Monte Carlo data are illustrated.
