We discuss many new subleading processes for inclusive production of W+W- pairs generally not included in the literature so far. We focus mainly on photon-photon induced processes. We include elastic-elastic, elastic-inelastic, inelastic-elastic and inelastic-inelastic contributions. Predictions for the total cross section and differential distributions in W - boson rapidity and transverse momentum as well as WW invariant mass are presented. The gamma-gamma components only constitute about 1-2 percent of the inclusive W+W- cross section but increases up to about 10 percent at large W+W- transverse momenta, and are even comparable to the dominant quark-(anti)quark component at large MWW, they are much larger than the gg → W+W- one.
