However, after the liberation of Byelorussia by the Red Army in July 1944, most of the pre-war civil administration was not possible for a number of reasons, one of which was that the city of Vileyka was heavily damaged during the war, and the transportation links between it and the rest of the region were too.

However, on 8 January 1954, in course of administrative-territorial reforms of the Byelorussian SSR, the neighbouring Polatsk and Baranavichy voblasts (along with others) were disestablished.

Molodechno Region incorporated 10 raions (Ivyanets from Baranavichy; Braslaw, Vidzy, Hlybokaye, Dzisna, Dokshytsy, Dunilovichi, Miory, Plisa and Sharkawshchyna from Polotsk) from the two regions with its size growing from 14.8 to 24.3 thousand square kilometres.

Its territory, with 848 thousand people, was divided between the modern Vitebsk (raions of Braslav, Vidzy, Hlybokaye, Dokshytsy, Dunilovichi, Miory, Plisa, Pastavy and Sharkawshchyna), Grodno (raions of Ostrovets, Oshmyany, Smorgon and Yuratishki and Bogdanov village of Volozhin) and Minsk regions (raions of Maladzyechna, Vileyka, Volozhin (except Bogdanov village), Ivyanets, Kryvichi, Myadzyel and Radashkovichy), with the city of Maladzyechna being incorporated into the latter.

This turned out to be the last of the administrative division reforms in Belarus, and since then, the borders of the regions remain today.
