How to Restore Preinstalled Office 2021 After Resetting Windows 11
Question details
The user needs to reinstall and activate their preinstalled lifetime version of Office 2021 Home & Student after reinstalling or resetting the Windows 11 operating system.
- Product
- Microsoft Office 2021 Home & Student
- Device & OS
- Windows 11
- Scenario
- Recovering preinstalled software licenses after resetting, reimaging, or cleanly installing a Windows 11 computer.
- Observed behavior
- The original Office applications are missing. A temporary Office installation may appear instead, which eventually expires and incorrectly prompts the user to purchase a new subscription.
Ensure you have the login credentials for the Microsoft account you originally used to set up the computer, as preinstalled digital licenses are permanently linked to the first account used to activate them.
Reinstall Office 2021 from Your Linked Microsoft Account
If you previously activated the preinstalled Office suite, the digital license is tied to your Microsoft account. You can reinstall the software directly from Microsoft's web portal.
When a Windows 11 computer is reset or reimaged using standard Windows tools, manufacturer-specific applications are often wiped. A standard Windows installation might load a trial version of Microsoft 365 by default, causing activation errors. You must download the specific 2021 version you own.
Click the Windows Start menu and search for 'Word', 'Excel', or 'PowerPoint'. If they appear, open one, go to 'Account', and check the activation status. If it says Microsoft 365 Trial, uninstall the trial from 'Settings' > 'Apps'.
Open your web browser and navigate to https://www.office.com/. Click 'Sign in' and enter the exact Microsoft account credentials you used when you first purchased or turned on the laptop.
Once logged in, click the 'Install Office' or 'Install apps' button near the top right of the dashboard. Select 'I have a product key' or locate 'Office Home & Student 2021' under your purchased products and click 'Install'.
Open the downloaded setup file to install the suite. After installation, launch Word, accept the license agreement, and sign in with your Microsoft account to activate the software.
Contact the Computer Manufacturer (OEM) for Support
If the digital license was never linked to a Microsoft account before the reset, the original equipment manufacturer (OEM) may need to help you recover the product key.
Try WPS Office: A Free, Lightweight Alternative to Office 2021
If you are unable to recover your preinstalled Microsoft Office license and want to avoid purchasing a new subscription, WPS Office provides a powerful, completely free alternative that seamlessly handles all your document needs.
- 1. Download the software: Visit the official WPS website and click the free download button for the Windows version.
- 2. Install WPS Office: Run the downloaded installer file. The installation takes only a few moments and requires minimal system resources.
- 3. Open your existing files: Launch WPS Office and directly open any of your existing Word, Excel, or PowerPoint files without losing any formatting.
Frequently Asked Questions
Why is my preinstalled Office 2021 asking me to buy a Microsoft 365 subscription?
When Windows 11 is reset, it often installs a default trial version of Microsoft 365. This trial conflicts with your lifetime Office 2021 license. You must uninstall the Microsoft 365 trial from your system settings and reinstall Office 2021 directly from your Microsoft account.
Is the product key for preinstalled Office 2021 stored in my computer's BIOS?
Unlike Windows OS activation keys, modern preinstalled Office licenses are generally not stored in the BIOS. Instead, they are digital licenses that permanently bind to your Microsoft account the first time you open an Office app and sign in.
What if I didn't link my preinstalled Office to a Microsoft account before resetting?
If you reset the PC before opening Office and activating it with a Microsoft account, the license remains unclaimed. In this scenario, you will need to contact your PC manufacturer with your receipt to request assistance in recovering the software.
Can I use a Windows recovery drive to get my preinstalled Office back?
Yes, if you use the official factory recovery image provided by your PC manufacturer (e.g., HP Cloud Recovery or Dell OS Recovery), it will restore the PC to its exact factory state, including preinstalled applications like Office. A standard Microsoft Windows 11 Media Creation Tool install will not include it.
