Solution 1Recommended

Claim the Digital License via Microsoft Store

Use this method to check if the Office 2021 license is digitally attached to your device's hardware and ready to be claimed.

Modern laptops typically do not include a physical product key card. Instead, the software is bound to the motherboard as a Digital Product Key (DPK) and must be claimed through your Microsoft account.

1
Open Microsoft Store

Click the Windows Start button, type 'Microsoft Store' into the search bar, and press Enter to launch the application.

2
Navigate to Library

Click on the 'Library' icon located in the bottom-left corner of the Microsoft Store window.

3
Check 'Included with device'

Look for a section or tab labeled 'Included with device'. If Office 2021 Home Edition is listed there, click the 'Claim' button to permanently link it to your Microsoft account.

Frequently Asked Questions

Why does my new ASUS laptop offer Microsoft 365 instead of Office 2021?

This typically occurs if the device's digital license wasn't properly synced during the initial Windows setup, causing the system to default to standard promotional prompts for a Microsoft 365 trial.

Where can I find the Office 2021 product key on my new laptop?

Modern laptops utilize a Digital Product Key (DPK) tied directly to the motherboard. You do not need a physical 25-character key; instead, you claim the license digitally via the 'Included with device' menu in the Microsoft Store.

Can the selected Windows region affect my Office activation?

Yes, selecting a region during the initial Windows setup that differs from the region where the laptop was officially sold can sometimes prevent the preinstalled Office 2021 license from being recognized.
