We present measurements of the anomalous WWgamma and WWZ trilinear gauge couplings from a combination of four diboson production and decay channels using data collected by the D0 detector at the Fermilab Tevatron Collider. These results represent the first high statistics combination of limits across different diboson production processes at the Tevatron and use data corresponding to an integrated luminosity of approximately 1 fb-1. When respecting SU(2)L x U(1)Y symmetry, we measure central values and 68% C.L. allowed intervals of kappagamma=1.07+0.16-0.20, lambda =0.00+0.05-0.04 and g1Z=1.05 +/- 0.06. We present the most stringent measurements to date for the W boson magnetic dipole and electromagnetic quadrupole moments of muW=2.02+0.08-0.09 (e/2MW) and qW=-1.00 +/- 0.09 (e/M2W), respectively.
