Q:

free software to remove background noise(Nosie of horns, other public disturbances) from video i shot

Free software to remove background noise(Noise of horns, other public disturbances) from video I shot, I tried Movavi but its free edition doesn't help much.

A:

The process that I have used with very good results goes as follows:

Use FFMPEG to split the Video and Audio to separate files
Use Audacity to deal with the noise by using noise filters, high/low filters & patching sections over.
Use FFMPEG to recombine the two files.

Both FFMPEG & Audacity are:

Free, Gratis & Open Source
Available for most platforms including Windows
