How to Restore the Default Windows Firewall Settings in Windows 7
Information
This will show you how to undo all of the changes you have made to the Windows Firewall settings and restore them back to the original default settings in Windows 7.
Warning
Restoring the default settings removes all of the Windows Firewall settings that you have made up to that point, for all network (Public and Private) location types. This might cause some programs that you have allowed through the firewall to stop working.
EXAMPLE: Default Windows Firewall Settings NOTE: These are the On or Off, and notification settings.
EXAMPLE: Default Windows Firewall Exceptions Settings NOTE: These are the program exceptions that are allowed through Windows Firewall to have internet or network access.
Here's How: 1. Open the Control Panel (All Items View).
2. Click on the Windows Firewall icon.
3. Click on the Restore defaults link in the left blue pane. (See screenshot below)
4. Click on the Restore defaults button. (See screenshot below)
5. Click on the Yes button to confirm. (See screenshot below)
6. Close the Windows Firewall window when done. (See screenshot below step 3)
That's it,
