Use the following guide to disable having to connect your PC with either M365 or a Domain while installing Windows 11.
Disconnect Network
Disconnect your network wire or Wi-Fi, and reboot your PC into the Windows 11 Installer
Command Prompt
Hit ‘Shift+F10’ on your keyboard to open a Command Prompt Window > Type ‘OOBE\BypassNRO’ > Enter.
Reboot
When you hit ‘Enter” (above) the PC will automatically reboot.
Network Screen
Once you get back to the Network Screen, you will now have the option – ‘I don’t have internet’.
NOTE: You may be prompted to Select ‘Limited Experience’ on another screen.
Continue Setup
Setup should now continue without prompting for M365 or Domain.
Don’t forget to reconnect your network!
