Share ubuntu-server 16.04 folder to windows host

So i have figured this on my own and this is the easiest solution:

just install samba with

sudo apt install samba

and go to this file:

/etc/samba/smb.conf

and just at the bottom add these lines:

[share]

comment = Ubuntu File Server Share
path = /path/to/the/folder  #for example /home/user_name/public <- this comment needs to be deleted!
browsable = yes
guest ok = yes
read only = no
create mask = 0755

restart the samba service

sudo service smbd restart
sudo service nmbd restart

and that's it, easy peasy :)
