To stop Microsoft from asking you to create/use an email address during the setup, (which is irritating and infuriating to say the least):

When it asks you to create/use an email address:

1. Use the Shift + F10 keyboard shortcut to open Command Prompt.
2. Type the following command to release the current network configuration and press Enter:ipconfig /release
3. Close the Command Prompt console.
4. Click the Back button.
5. Confirm the name of the local account.
6. Click the Next button.
7. Create a password for the account.
