What were the main changes brought about by the Bolsheviks immediately after the October Revolution?

Dear student,

The main changes brought about by the Bolsheviks immediately after the October Revolution were-

1. Banks and Industries were nationalized.
2. Land was declared social property, thereby allowing peasants to seize it from the nobility.
3. In urban areas, houses were partitioned according to family requirements. 
4. Old aristocratic titles were banned, and new uniforms were designed for the army and the officials.

Regards.
