If Microsoft Office was deleted accidentally, reinstall it based on how it was originally obtained:
- For a Microsoft 365 subscription or a retail Office purchase linked to a Microsoft account, sign in with the same Microsoft account originally associated with the product, then reinstall Office from the install page.
- If Office came preinstalled on the PC and did not require a product key or Microsoft account for activation, reinstall it from the Microsoft Store app:
- Open Start > Microsoft Store.
- Select Library > Apps tab. If All appears, select All instead.
- Turn off Show installed products only under Sort and filter.
- Find the Office product and select the Cloud button.
- Follow the prompts to complete installation.
If reinstalling fails, try this recovery path:
- Restart the PC.
- Run the Office uninstall troubleshooter to completely remove any broken Office remnants, then restart when prompted.
- It works for Microsoft 365, Office 2021, Office 2019, and Office 2016.
- It cannot uninstall Office 2024.
- It must be run on the same Windows PC and requires Windows 10 or later.
- Reinstall Office again using the correct install method above.
If Office disappeared after a Windows Recovery or Reset, use the ReadMe file copied to the desktop after recovery, then follow the reinstall steps for the Office version listed there.
