Whether you’ve purchased a physical copy or downloaded Office online, you’ll need your product key to complete the installation process.

## Where to Find Your Microsoft Office Product Key

Your product key location depends on how you acquired Microsoft Office:

– Pre-installed versions: Often found on a sticker on your device or in the documentation

Before activation, ensure you’ve installed the Office suite on your computer. You can download it from office.com if you haven’t already.

### Step 2: Launch an Office Application

Open any Office application (Word, Excel, PowerPoint) to begin the activation process.
