Windows Firewall blocks incoming network connections to your computer to help protect it from malicious programs trying to connect to your computer and steal your data. Note that it does not block outbound connections, so if spyware or malware does ever get installed on your computer, it can send out data without any restriction.
Overall, having the firewall turned on is good, but there are many occasions when Windows Firewall blocks incoming connections for legitimate programs. Most of the time, you’ll get a dialog box asking you whether or not to unblock a program, but sometimes you have to add an exception to the Firewall list manually.
