Router — Static IP setup

Set a DHCP reservation for your main PC so it always gets the same IP:

1. Open your router admin panel (usually 192.168.1.1 or 192.168.0.1)
2. Find DHCP Reservations or Address Reservation
3. Add your main PC MAC address with a fixed IP
4. Save and reboot router

To find your main PC MAC address: run ipconfig /all in CMD and look for the Physical Address of your active WiFi or Ethernet adapter.

Uninstall

Double-click UNINSTALL.bat in the /windows folder to remove everything cleanly.
