Do not purchase a subscription yet; first check whether Word has lost access to an existing one-time Office license or an expired subscription.
Check what license you already own
- Close Word and other Office applications.
- Open Services & subscriptions and sign in with the Microsoft account originally used to obtain Office.
- Look under Subscriptions, Cancelled subscriptions, or purchased products:
- Office 2016/2019/2021/2024 or a standalone Word purchase: this is a one-time license, so you should activate that product rather than buy Microsoft 365.
- Microsoft 365 marked expired: the installed desktop Word depended on that subscription and requires renewal for continued desktop use.
- No Office product listed: try any other personal email address that may have been used when Office was first installed or purchased.
Microsoft states that using the wrong account can produce “We couldn't find any Office products” and leave Office unlicensed.^1^
Restore an existing license
If the correct Office product appears in the account:
- Open Word → File → Account.
- Sign out of any account currently shown.
- Sign back in with the account that owns the listed Office product.
- If offered, select Activate Product or Reactivate.
- Close and reopen Word.
If Word remains unlicensed, run the Microsoft 365 activation troubleshooter from Microsoft’s activation-support page. It must run on the affected computer and requires Windows 10 or later.^1^
Also check Control Panel → Programs → Programs and Features. Search for “Office.” If multiple Office versions are installed, they can conflict with activation. Uninstall only the version you do not own or use, restart Windows, and reactivate the remaining version.^1^
If Office came with the laptop
Preinstalled Office is not always a permanent free copy. It may have been:
- A time-limited Microsoft 365 offer.
- A subscription supplied by an employer, school, or another family member.
- A one-time purchase digitally associated with the Microsoft account used during initial setup.
For an included one-time purchase or Microsoft 365 offer, the license is activated by signing in and is then added to that Microsoft account.^2^
The fact that this is the same laptop does not by itself confirm which license was originally used. The decisive information is what appears under Services & subscriptions and in Word → File → Account.
Use Word without paying
If no desktop license belongs to the account, Word’s web version remains free:
- Go to Microsoft365.com.
- Sign in with a free Microsoft account.
- Open Word from the app launcher.
- Upload an existing document or create a new one.
Free accounts receive the web versions of Word, Excel, and PowerPoint; the installed desktop Word application requires an eligible desktop license or subscription.^3^
