Microsoft Word for Windows
Microsoft's word processor for documents, resumes, and reports, with styles, track changes, and real-time co-authoring via OneDrive.
Updated August 9, 2026 · Reviewed by SoftNexi Editorial Team, Software research and documentation
Overview
Microsoft Word is the word processing app in the Microsoft Office lineup, used for everything from short letters to long, styled reports with tables of contents, footnotes, and citations. It's available through a Microsoft 365 subscription or, in some regions, as part of a one-time Office purchase.
Word's strength is its combination of a mature styles system (heading levels, paragraph styles, and templates that keep long documents consistent) with collaboration features like Track Changes, inline comments, and, when a file is stored on OneDrive or SharePoint, real-time co-authoring with other people editing simultaneously.
Compared with free alternatives like LibreOffice Writer or ONLYOFFICE, Word remains the reference implementation for the .docx format, so complex formatting, legacy macros, and enterprise templates are most likely to render exactly as intended in Word itself. That fidelity is the main reason organizations that exchange complex documents standardize on Word rather than a compatible alternative.
Word is not sold as a separate standalone download from Microsoft's consumer store in most cases — access comes through a Microsoft 365 subscription (see the Microsoft 365 record) or a one-time Office suite purchase, both managed through your Microsoft account.

How to install Microsoft Word
1. Get access via Microsoft 365 or Office
Word installs as part of a Microsoft 365 subscription or a one-time Office purchase; see the Microsoft 365 record for plan details.
2. Download the Office installer
From account.microsoft.com/services, download and run the installer that includes Word.
3. Sign in to activate
Open Word and sign in with the Microsoft account tied to your subscription or license to activate it.
4. Set your default save location
Choose whether documents default to saving on OneDrive or locally under File > Options > Save.
How to use it
1. Apply styles consistently
Use the Styles gallery on the Home tab rather than manually formatting text, so headings and a table of contents stay consistent.
2. Track changes during review
Enable Review > Track Changes before sending a document out for edits, then use Accept/Reject to process feedback.
3. Co-author in real time
Save the document to OneDrive and use the Share button to invite others; simultaneous edits appear live with each person's cursor labeled.
4. Run the Editor
Check the Editor pane (Review tab) for grammar, clarity, and conciseness suggestions before finalizing a document.
Safety and privacy
- Access Word only through microsoft.com or the Microsoft Store to avoid counterfeit license sellers.
- We have not independently audited Word's telemetry beyond Microsoft's own published documentation.
- Bundled software
- Not applicable; Word installs as part of a Microsoft 365 subscription or Office suite, not as a standalone bundled installer.
- Privacy
- Word requires a Microsoft account to activate and can optionally connect to OneDrive for saving and co-authoring; local-only saving is also supported.
Known risks
- Documents with macros from unknown sources can carry malware risk; keep Protected View and macro warnings enabled.
- Phishing emails often impersonate Word/OneDrive sharing notifications — verify sender addresses before opening links.
