For anyone wondering how to do this - on the first setup screen asking you to pick a language after you turn the laptop on, hit Shift + F10, which will bring up the console. Click on it and type:

oobe/bypassnro

This will restart the computer, and setup will appear unchanged. When you get to the step asking you to connect to a network, select “I don’t have Internet.” This will prompt the creation of a local account. Enjoy your Microsoft account free computer!

If you’ve already connected to the Internet but haven’t created the account, open the console and type:

ipconfig /release

Which will force the computer to disconnect from the internet. From there you can use the oobe command from before to reset and set up without a Microsoft account.
