Just changed two rules in Windows Firewall to blocked and it appears to no longer send anything. https://i.imgur.com/a5yu5vb.png Wondering if I should go through all the Windows stuff there and turn them off. Edit: just did (except for Edge and obvious internet related stuff). Is there a way to change Firewall rules with a registry tweak? That would be the ideal way to distribute this.
You can get the rules and enable/disable them easily.
