Reddit user Gamerminstrel noticed a key message that pops up during the Windows 11 installation process that says you can, of course, only sign in to a Microsoft account if your PC is connected to the internet. The user explains that simply disconnecting the setup process from the internet will allow users to create a local account instead of being required to create a Microsoft account.
A command prompt can be used to terminate the connection. The prompt window can be opened by holding down the Shift and F10 keys during the Windows 11 installation process. From here:
Type ipconfig /release (note the space between ipconfig and the slash) and press Enter
Close the command prompt box and click back in the installation process
The option to create a local account should now be available
Click on Create a local account and proceed with the configuration
The command prompt cuts off your computer’s connection to the internet, essentially making it forget how to connect. Once the configuration process is complete, you can restore your connection by opening the command prompt again (shift+f10) and typing “ipconfig /renew” before hitting enter – or simply restarting the computer. Reddit user AppropriateEvent6446 also claims that one of the following command prompt entries will allow you to bypass Windows 11 Internet requirements: “oobebypassnro”, “oobe /bypassnro”, “oobe/bypassnro” and “cd oobe ( press Enter, then) -> bypassnro.cmd.”
