Microsoft Word is part of Microsoft Office and requires an up-front purchase or a Microsoft 365 subscription. If you're using a computer without Word installed, there are other ways to view that DOCX or DOC file.

Microsoft once offered a free "Word Viewer" application that would let you view Word documents, but discontinued it back in November 2017.

Here are some other ways you can view Word documents on a Windows PC:

  • Download Word Mobile from the Store on Windows 10. The mobile version of Word lets you view (but not edit) Word documents. You can install it for free. It's intended for tablets but runs in a Window on a Windows 10 desktop PC.
  • Upload the document to Microsoft OneDrive and open it from the OneDrive website. It will open in Microsoft Word Online, a free web-based version of Word. You can even edit documents in Word Online---no purchase necessary. You just have to use your browser.
  • Install LibreOffice, a free and open-source office suite. This is an alternative to Microsoft Office. LibreOffice Writer, which is included, can open and edit Microsoft Word documents in DOC and DOCX format.
  • Upload the document to Google Drive and open it in Google Docs, Google's free web-based office suite.
  • Get a free month-long trial of Office 365 to get full access to Microsoft Word and the rest of Microsoft Office for free---for a limited time.
