If you are looking for a simple and light firewall (but still better than Windows Firewall), I recommend using Simplewall. It does not require a kernel extension and works with the API provided by Windows to do network filtering.

Thanks this is great, it would be nice to have one to compare with LS just for the sake of features similiar too.

Simplewall is amazing- and is impressive in how it's able to stop a lot of Microsoft's attempts to get Telemetry out.

I've been looking at Portmaster for a while- it seems to be a valid option for those of us who dabble with the idea of totally halting the telemetry despite it being designed to be hard to stop
