At the end of the setup process, create a local account, don't use Cortana and turn off everything in the privacy settings. If you already installed Windows with the default settings, go to Start > Settings > Privacy to turn them off. You should also go to Account and disconnect your Microsoft account because this guide will prevent it from working properly. Once you get to the desktop, go to Settings > Updates and security, and let it download all the updates. Reboot and repeat until no more updates are available. This is important because Windows Update may interfere with our activities. Now open the Store app, and let it download updates too. Again, this is important because updates would interfere with our activities. This may take some time, and it may even get stuck. If it happens, reboot and try again. Make sure you check for updates several times, because we absolutely don't want it to try and download stuff while we're removing it.
