In the "Let's connect you to a network" page, use these steps:
* Use the Shift + F10 keyboard shortcut to open Command Prompt.
* Type the following command to release the current network configuration and press Enter: oobe\bypassnro
Note: The command is a single phrase without spaces.
Note2: This will reboot the machine and restart the installer again (why?? because fu for not wanting a MS account that's why)
