Selected measurements done with W and Z bosons detected in the CMS detector, based on samples of events collected during 2011 at 7TeV and 2012 at 8TeV physics runs, are presented. Results on the inclusiveWand Z cross sections
and the lepton charge asymmetry in the reconstructedWevents decaying to a lepton and a neutrino, obtained in the electron and muon decay channels, are presented.
Differential cross section, forward-backward asymmetry and electroweak couplings of events coming from the Drell-Yan process are compared with the corresponding theoretical QCD prediction comparison
