The user needs to reinstall and reactivate Microsoft Office 2019 after downgrading from Windows 11 to Windows 10, but has lost access to the Microsoft account password required for activation.
- Product
- Microsoft Office 2019
- Device & OS
- Windows 11 / Windows 10
- Scenario
- Reinstalling the Office suite after a system reset or operating system downgrade.
- Observed behavior
- Microsoft Office was removed during the Windows reset, and the user cannot sign in to download the installer due to a forgotten Microsoft account password.
Gather any old passwords, alternate email addresses, and phone numbers that might be associated with the Microsoft account you originally used to purchase or activate Office.
Use the Microsoft Account Recovery Form
Recover your lost Microsoft account to regain access to your digital Office 2019 license and reinstall the software.
Modern versions of Microsoft Office are permanently linked to your Microsoft account. To reinstall Office after a system reset, you must first recover account access so you can download your licensed installer.
Open a web browser and go to the official Microsoft account recovery form via account.live.com/acsr.
Type in the email address, phone number, or Skype name of the Microsoft account associated with your Office 2019 license.
Enter a different, working email address where Microsoft support can contact you, then complete the security captcha characters.
Answer the security questions and provide as much historical account information as possible, such as old passwords and recent email subjects, to verify your identity.
Once Microsoft restores your account access, sign in at office.com, navigate to 'Services & subscriptions', and click 'Install' next to your Office 2019 product.

Frequently Asked Questions
Why was Microsoft Office uninstalled when I downgraded Windows?
When you reset or downgrade your Windows operating system, the process typically wipes third-party applications to ensure a clean system state. You must manually reinstall software like Microsoft Office afterward.
Can I use my Office 2019 product key instead of signing in?
No. Once an Office 2019 product key is redeemed, the license is permanently bound to the Microsoft account used during activation. You must recover and sign in with that specific account to reinstall the software.
What happens if my Microsoft account recovery request is denied?
If your request is denied, you can submit the form again with additional or more accurate information. You can attempt the recovery form up to two times per day.
Will my old Word and Excel files be deleted?
If you chose to keep your personal files during the Windows downgrade, your local documents should remain intact. Documents saved to OneDrive will also be safe and accessible once you regain access to your Microsoft account.
