We present a new program (iHixs) which computes the inclusive Higgs boson cross section at hadron colliders. It incorporates QCD corrections through NNLO, real and virtual electroweak corrections, mixed QCD-electroweak corrections, quark-mass effects through NLO in QCD, and finite width effects for the Higgs boson and heavy quarks. We focus in particular on the Higgs width effects and results using the recently added NNPDF21 parton distribution functions. Cross section predictions are provided for the 8 TeV LHC in the mass range from 114 to 131 GeV
