- Scenario
- Setting up a newly purchased Dell computer and attempting to activate the bundled Microsoft Office software.

Contact the Seller and Review Your Purchase Invoice
Since Office Professional Plus 2021 is a volume/business license, the third-party seller or retailer is responsible for providing the key.
Office Professional Plus 2021 is generally a volume or business edition and is not normally sold as a lifetime consumer subscription directly by Dell. If you purchased a Dell PC from a third-party shop or retailer that included this software, that specific seller is responsible for providing the license.
Locate your original purchase invoice, physical receipt, or confirmation email from the shop where you bought the Dell computer.
Scan the documentation for a 25-character registration code or a dedicated software bundle section.
If the key is missing, contact the specific retailer's customer support, as they are the only ones who can provide the product key for this specific volume edition.

Check if Office is Already Installed and Activated
The shop may have pre-installed and activated Office for you, meaning no product key is required.
Uninstall Conflicting Microsoft 365 Trials
New computers often come with Microsoft 365 pre-installed, which can prevent Office 2021 from activating properly.
Switch to WPS Office for a Hassle-Free Experience
If you are unable to recover your Microsoft Office product key from the retailer, consider switching to WPS Office. It is a free, lightweight, and highly compatible office suite that requires no complex activation codes.
- 1. Visit the website: Go to the official WPS Office website on your Dell computer.
- 2. Download the software: Click the Free Download button to get the latest installation package.
- 3. Install and launch: Run the installer and start creating documents immediately without a product key.

Frequently Asked Questions
Why doesn't Dell provide the product key for Office Professional Plus 2021?
Office Professional Plus 2021 is typically a volume-licensed business edition and is not normally sold as a lifetime consumer product. Because it is rarely sold directly by PC manufacturers like Dell for home use, the third-party shop or retailer that configured and sold you the PC holds the responsibility for providing the license.
Do I actually need a product key if Office is already installed on my new PC?
Not necessarily. If the retailer pre-installed and activated the software before shipping the computer to you, you may not need a key to use it. You can check by searching for 'Word' in your Windows search bar and opening the application to see if it prompts for an activation code.
What should I do if my Dell PC came with a Microsoft 365 trial?
If your computer came with a pre-installed Microsoft 365 Family trial, it can conflict with your permanent Office 2021 installation. You should uninstall the Microsoft 365 trial version through Windows Settings > Apps before attempting to use or activate your Office 2021 software.
