Reinstall Office 2019 from your Microsoft Account

Since Office 2019 is a digital license tied to your Microsoft account, you do not need the original 25-character product key to reinstall it after formatting your hard drive.

When Office Home and Student 2019 was initially redeemed, the license was permanently linked to your Microsoft account. Reinstalling simply involves logging into the Microsoft portal and downloading the installer directly to your newly formatted PC.

If you encounter an activation error stating the software is already installed on another device, you may need to use the deactivation option in your Microsoft account to release the old installation.

1
Access the Microsoft Account dashboard

Open a web browser on your formatted HP laptop and navigate to account.microsoft.com.

2
Sign in with the linked account

Log in using the exact Microsoft email address and password that you used to originally activate Office 2019.

3
Navigate to Services & Subscriptions

Click on the 'Services & subscriptions' tab in the top navigation menu to view all digital licenses tied to your account.

4
Download the Office installer

Locate 'Office Home and Student 2019' in the list of purchased products and click the 'Install' button. Follow the prompts to download the setup file.

5
Run the installation

Open the downloaded setup file and follow the on-screen instructions to complete the installation. Office will automatically activate once you sign in.

Frequently Asked Questions

Do I need my original 25-character product key to reinstall Office 2019?

No. Once a product key for Office Home and Student 2019 is redeemed, it is permanently linked to your Microsoft account. You only need to sign in to your Microsoft account to reinstall and activate the software.

What if I forgot which Microsoft account is linked to my Office 2019 license?

If you cannot remember the account, try logging into account.microsoft.com with any email addresses you might have used. Check the 'Services & subscriptions' section of each account until you find the one that lists your Office 2019 purchase.

Does using the 'Reset this PC' feature in Windows remove Microsoft Office?

Yes. If you choose to 'Remove everything' during a Windows reset, it functions similarly to a format and will uninstall all third-party applications, including Microsoft Office. You will need to reinstall it afterward.

Why is Office telling me my license is already in use after reinstalling?

Because Office Home and Student 2019 is a 1-PC license, Microsoft's activation servers might still recognize your pre-format installation. You may need to select the option to sign out of the previous installation or use the automated telephone activation system to complete the process.
