  We discuss new subleading processes for inclusive production of $W^+ W^-$
pairs. We focus mainly on photon-photon induced processes. We include
elastic-elastic, elastic-inelastic, inelastic-elastic and inelastic-inelastic
contributions. The inelastic photon distributions in the proton are calculated
in two different ways: naive approach used already in the literature and using
photon distributions by solving special evolution equations with the photon
being a parton in the proton. The results strongly depend on the approach used.
The resolved photon contribution was calculated in addition and found to be
small. We also calculate the cross section for single-diffractive production of
$W^+ W^-$ pairs including pomeron and reggeon exchanges in the Ingelman-Schlein
model. Finally we only mention here about double parton contribution which is
interesting by itself.
