Bought a bundle such as Office 2024 Pro Plus with Windows 11 Pro? Each key in the bundle is separate: follow the guide for each product in turn, starting with Windows.

Five tips for a smooth activation

  1. Download only from Microsoft or the link in your order email. Never use third-party mirror sites.
  2. Match the edition to the key. A Pro key activates Pro, a 2021 key activates 2021.
  3. Remove trials and older versions first, especially Microsoft 365 trials before installing Office.
  4. Copy and paste the key to avoid typos like O and 0 or B and 8.
  5. Keep your order email. It's your proof of purchase and you may need the key again to reinstall.
