It is well established that gas accretion onto SMBH powers Active Galactic Nuclei over the entire range of their observed properties such as mass and luminosity, and over the entire cosmic history. Gas outflowing from the AGN power source is most likely responsible of the complex interplay between the nuclear engine and the host galaxy properties, which is commonly referred to as feedback. Winds propagating at much larger scales (Galactic outflows) can represent a crucial diagnostic of AGN feedback. Both numerical simulations and observations have shown that the nature of outflows in AGN is multiphase, and that each gas phase embeds a fundamental piece of information on the driving mechanism and on the effect on the host galaxy. In this talk I will review the progresses obtained in the past 2 years to shed light on the presence and effects of Quasar winds, and on the multi-phase nature of such phenomena.
