We had to deploy a fully configured Windows 10 environment to over 50 touchscreen computers. These computers had a single task and were not allowed to access internet resources (except for administrators).
To reach this goal a set of firewall rules were created blocking all traffic beneeth and above the local network IP range. This tool can create, activate and deactivate these firewall rules allowing the administrator by simply pressing a button to get internet access.
The first time wwwBlock is started it elevates itself by registering with the highest privileges. The Windows User Account Control (UAC) will prompt for confirmation. As long as it is started from the same folder this confirmation is not needed after the first run.
