We consider the full process e{sup +}e{sup {minus}} {yields} W{sup +}W{sup {minus}} {yields} 4f. We show that the off-shell effect are sizable and comparable to radiative effects. We give the exact results for hard bremsstrahlung processes e{sup +}e{sup {minus}} {yields} (4f + {gamma}) and the results of the O({alpha}) improved cross sections for e{sup +}e{sup {minus}} {yields} W{sup +}W{sup {minus}} including photon radiation. The status of the virtual corrections to the 4f-process is described.
