Many people are using my method to install a local account instead of an MS online/cloud account by using the URI ms-cxh://
During OOBE, press Shift+F10 to open CMD and type: start ms-cxh://localonly to create a local user account and continue the installation from there. Note however, this method is known to Microsoft, and will be blocked in future builds.
You won't find the parameters that the URI ms-cxh:// can use anywhere online or in the Windows registry, as MS does not publish them - they're hidden inside files.
The URI command ms-cxh://localonly , for example, can be found in the file: C:\Windows\SystemApps\Microsoft.Windows.CloudExperienceHost_cw5n1h2txyewy\js\errorHandler.js
This file was found using the Super God Mode script , which runs a Powershell script to search within files for hidden URIs.
BTW, you can run a similar search using Notepad++ :
Open Notepad++ as admin > Search > Find in files > Enter the search string, for example ms-cxh: and directory, for example C:\Windows > CHECK "In all subfolders, CHECK "in hidden folders".
Add a filter if you like, for example: *.* !*.dmp !*.msi !*.msp !*.etl !*.log !*.jpg !*.png !*.wim !*.sys
and click "Find all". Wait for the results, they will appear at the bottom pane.
There are other ways to perform a deep search, such as using MS Sysinternals strings, Geoff McDonald's strings2 or Mandiant's floss.
