To install Word on Windows 10, go to microsoft365.com, sign in with the Microsoft account you used for Microsoft 365 or Office, select Install apps, and run the file that downloads. Word installs with the other apps in your plan.
Applies to: Microsoft 365 and Office 2021 or later on Windows 10.
What you need
- A Microsoft 365 subscription or a one-time Office purchase that includes Word.
- The Microsoft account linked to it.
- An internet connection. The download is several gigabytes.
If you don’t have either, you can use Word for the web free at microsoft365.com in your browser.
Install Word
- In your browser, go to microsoft365.com and sign in.
- Select Install apps (or Install Office), then Microsoft 365 apps.

- Open the file that downloads (it starts with Setup or OfficeSetup). Select Yes if Windows asks for permission.
- Wait for You’re all set! Office is installed now and select Close.

- Open Word. If you can’t find it, these ways to open Microsoft Word in Windows 10 will help.
Find and pin Word after installing
Select Start and type Word. Right-click Word and select Pin to taskbar or Pin to Start so it’s always one click away. The first time you open it, sign in with the same Microsoft account and accept the license agreement. Word may also ask you to choose a file format; keep the default Office Open XML formats unless you share files with very old software.
Using Word on Windows 10 now that support has ended
Windows 10 reached end of support in October 2025, but Word still installs and runs on it:
- Microsoft 365. Microsoft will keep sending security updates for the Microsoft 365 apps, including Word, on Windows 10 until October 10, 2028. New features may only come to Windows 11.
- Office 2021 and Office 2024. These one-time purchases still work on Windows 10, but Microsoft no longer supports them there.
If your PC can run Windows 11, upgrading is the safer long-term choice.
If the install fails
- Restart the PC and run the installer again.
- Make sure you have enough free space and a steady connection.
- If an older version of Office is in the way, uninstall Microsoft Office first.
- There’s no Install apps button. Your plan may not include desktop apps, such as some business plans, or you may be signed in with a different account. Check which account bought Office at microsoft365.com.
- Word shows “Unlicensed Product” after installing. Select File > Account and sign in with the Microsoft account linked to your purchase.
- The installer stops partway. Use a wired or stronger connection, restart the PC, and run Setup again. It continues where it left off.
- You see an error code. Search the code on Microsoft Support. Most install errors are fixed by removing old Office versions and restarting.
