Learning that lasts. Online courses from $14.99
If you need a system running a Microsoft Windows operating system to function as a Trivial File Transfer Protocol (TFTP) server, one free solution is the SolarWinds TFTP server program available from the company's website at TFTP Server. After installation of the software, if you open the application, you will see that the TFTP service is started and listening for data on User Datagram Protocol (UDP) port 69.

If you open a command prompt window and issue the command netstat -anp udp and pipe the output into the find, you should also see the system is listening on all network interfaces, i.e., 0.0.0.0, on UDP port 69.

C:\Users\Public\Downloads>netstat -anp udp | find "0.0.0.0:69"
  UDP    0.0.0.0:69             *:*

C:\Users\Public\Downloads>

The installation program also installs a TFTP service, which is set to run automatically when Windows boots; you can see information on the service if you open Services and scroll through the list of services on the system — you can open a Services window by typing services.msc at a command prompt window and hitting Enter.

The installation program creates a C:\TFTP-Root directory as the root directory for files that will betransferred by TFTP. You can change that directory, if you wish, once the software is installed, by clicking on File and then selecting Configure and then changing the root directory. At the configuration window, you can also control whether an icon is added for the TFTP server to the Windows System Tray.
