The administrative centre of the region was the city of Vileyka.

Also, during the German occupation between 1941 and 1944, Ashmyany District was part of Wilna Land General Bezirk at Litauen and the city of Vileyka Glubokoye was part of General Bezirk Weissruthenien in Reichskommissariat Ostland.

On 20 September 1944, the oblast was renamed to Molodechno Region, and the administrative centre was relocated to Maladzyechna. On the same day, Vidzy, Hlybokaye, Dzisna, Dokshitsi, Dunilovichi, Miory, Plisa, and Sharkovshchina Districts, as well as Kuropolye village in Postavy District were transferred to Polatsk Voblast, and the Iwye, Valozhyn, and Yuratsishky districts of Baranavichy Region were transferred to Molodechno.
