OK, first check what the network settings are for your Linux install Find under 'Preferences' -- 'Network', it should open showing the basic network connection information (connection speed, IPv4 address, IPv6 address,hardware address, default route, DNS) if you don't have an IPv4 address in the range supplied by the DHCP server of your router you have problems which need to be fixed first.
The 'gear' symbol, bottom right, opens a page that allows you to edit settings except for the 'Details' page.
Once you are satisfied the network settings are correct you can close the network window.
Now open either the 'Computer' or 'Home' 'File Browser' window and click on 'Network' down arrow, then click on what is displayed, this should open a window showing all items it can read (it generally shows SMB/CIFS items as 'Windows Network', double clicking on that should show all your running SMB/CIFS servers (remember you will not see your win 10 box because it is not running while you are booted into your live linux USB stick).
I hope this helps bur remember I am using a full Linux Mint install on a real computer whereas you are using a live linux from a bootable USB.
