Processes in Microsoft 365 for setting up Office apps, redeeming product keys, and activating licenses.
To use Word without being asked to buy a new subscription, Office must be installed and activated with the same Microsoft account that owns the Home/Student or Home/Office product, not a Microsoft 365 trial or different account.
Follow these steps:
- Remove wrong Office versions
- In Windows, go to Settings > Apps > Installed apps.
- Uninstall any of these if present:
- Microsoft 365 (trial or subscription)
- Office Trial
- Any other Office versions that are not the Home product that came with the computer.
- Restart the computer.
- Sign in with the correct Microsoft account
- Open a browser and go to the Services & subscriptions page:
https://account.microsoft.com/services. - Sign in with the same Microsoft account that was used to redeem/activate the Home Office product when the computer was new.
- Confirm that the product (for example, “Office Home & Student 2021”, “Office Home 2024”, or similar) appears under Services & subscriptions.
- If it does not appear, sign out and try any other Microsoft accounts that might have been used.
- Open a browser and go to the Services & subscriptions page:
- Reinstall from the account page
- On the Services & subscriptions page, next to the correct Office product, select Install > Install on this device.
- This downloads the correct one‑time‑purchase installer.
- Run the downloaded setup file and complete the installation.
- Activate Office in Word
- Open Word.
- When prompted to sign in, use the same Microsoft account confirmed in step 2.
- Go to File > Account in Word and check that the product name shows the Home product (for example, “Office Home & Student 2021”) and that it is activated.
If Word still opens documents as read‑only or shows “Buy” or “Subscribe” buttons, it usually means either:
- A Microsoft 365 trial/subscription is still installed and taking precedence, or
- Word is signed in with a different Microsoft account than the one that owns the Home product.
Removing the trial/subscription and reinstalling from the correct account, as above, resolves this in typical home scenarios.
