Mistakes to avoid
Typing instead of copy-pasting
Characters like B/8, O/0 and G/6 look identical. Always paste your key directly from the email.
Using a work or school account
Retail licenses require a personal Microsoft account (Outlook.com, Hotmail, Live), not a work or school account.
Active VPN during activation
If you're behind a VPN, disable it temporarily during activation to avoid region errors.
