Office 2021 runs on almost any Windows 11 or Windows 10 PC. Here's what Microsoft recommends:
Office 2021 Professional Plus is activated by telephone: you install Office, enter the key, and confirm the activation through Microsoft's automated phone line. It takes about ten minutes.
Keep your key: if you reinstall Windows or Office, you'll activate by phone again.
No. Office 2021 is a one-time purchase, you pay once, there are no monthly or yearly fees and the licence doesn't expire.
Office 2021 is bought once for one PC. Microsoft 365 is a subscription with 1 TB of OneDrive storage and always the newest features, but you pay every month or year.
No, this is the Windows PC edition of Office 2021. It runs on Windows 11 and Windows 10.
After entering the key, Office shows an installation ID. You call Microsoft's automated activation line for your country, type the ID in, and enter the confirmation ID you hear back into Office. No account is needed.
Microsoft ended support on October 13, 2026. Office keeps working, but without security updates.
