Software to track what my programs send on the internet

Heya guys.

Im playing now with a trial version of software that every time I run it checks main website to see if my trial hasn't ended so I'm planning to redirect the server's IP to localhost and create a script that will show the same result (response) every time .this way the software will think Im still on trial..

Now the question is... how can I monitor what strings the software is sending and receiving from the main website?
I need a software tht does that on Windows

Help is appreciated.

You can try with wireshark(free) or httpanalyzer(paid). The software probably calls home on port 80, so you should see exactly what it sends(GET/POST) and make your script based on that

Thank you I installed wireshark. and got the packages hoever the software it makes a chekcing like this to make sure the infos are from the main website and not a clone
