%X We discuss central exclusive production of W<sup>+</sup>W<sup>−</sup> pairs in proton-proton collisions at LHC. Predictions for the total cross section and differential distributions in transverse momentum of W<sup>±</sup> and WW invariant mass are presented. We discuss both γγ→ W<sup>+</sup> W<sup>−</sup> mechanism as well as a new mechanism of exclusive diffractive production. The amplitude for the latter process is calculated in the Durham model. We compare the two (QED and QCD) types of contributions. The diffractive contribution is only a small fraction of fb compared to the γγ contribution which is of the order of 100 fb. This opens a possibility of searches for anomalous four-boson γγW<sup>+</sup> W<sup>−</sup> coupling due to physics beyond Standard Model.
