I had some free time around the holidays so I made a privacy tool for windows, it features a complete management interface for the windows firewall and a tweak engine to set and monitor relevant options (GPOs, reg tweaks, removing execute permission from binaries, etc…) to block windows telemetry, and communication with M$ as far as reasonable.
The tweak collection is based on the Windows Restricted Traffic Limited Functionality Baseline, adding some custom tweaks, etc……
