To let users connect to your Mac from a Windows computer, turn on file sharing and enable SMB sharing.
Set up file sharing on the Mac
On your Mac, choose Apple menu

next to File Sharing.Turn on File Sharing.
Click Options, then turn on “Share files and folders using SMB.”
In the Windows File Sharing list, select the checkbox next to each user account that needs to share files with Windows users and enter the passwords for those users, then click OK.
Click Done, then click Done.

Click WINS in the sidebar, then enter the workgroup name used by the Windows computer.

Provide the information Windows users need
To connect to your Mac, Windows users need the network address for your Mac, and a user name and password to use to log in to your Mac.
To find your Mac computer’s network address, choose Apple menu
Create an account on your Mac for each Windows user. To create accounts, choose Apple menu
in the sidebar. (You may need to scroll down.) See Add a user or group.Open Users & Groups settings for me
If you want to use an account that existed before you installed the latest version of macOS, you may need to reset the password for the account in Users & Groups settings.
Because the passwords of user accounts used for Windows sharing may be stored in a less secure manner, turn off the account when it’s not being used. Before you turn off Windows sharing, turn off all the accounts you enabled. Otherwise, the passwords are still stored less securely.
