This is a very easy thing to do, no need for any chuncky softwares.
Go to Windows movie maker.
import your video, make sure you are in timeline mode.
put it all on the timeline
now select all of the audio and right click it
there you will see 'volume' click on that and set it.

Its as simple as that.

I Hope This Helps
