Make sure Port UDP 69 is allowed through Windows Firewall

Even if your windows Firewall is disabled , make sure its disabled on Guest Networks as this will usually be the network the management speaks on not domain

Make sure the machine you are using does not have WDS enabled , WDS uses TFTP 

Run TFTP and make sure the server is listening on an Network IP ( NOT 172.0.0.1 )

Copy the .xos file to the TFTP Directory 

In SSH make sure you can Ping the IP of the TFTP server from the Switch viaping %IP OF TFTPServer%

Do you want to install image after downloading? (y – yes, n – no, – cancel) Yes

You will need to reboot the switch and if the switch is in a stack you will need to reboot them both as Stack switches cannot be in different versions
