Windows Firewall

Windows Firewall can help protect your PC from hackers and malicious software. In Windows 7, it is still powerful—but we have made it more flexible and easier to use.

For example, now you can fine-tune the protection and notifications you want for each of your network profiles—Home, Work, and Public. When you are connected to a public network like a library or a coffee shop, you may want to block all incoming connections. At home or work, this might be overkill. Whatever level of protection you choose for your profiles, you will be able to switch between them with ease.
