Why Change or Update Your Office 2024 Product Key?

There are several legitimate reasons for updating your Office 2024 Professional Plus key:

• New Purchase or Device Replacement: Migrating licenses to a new PC or activating with a newly purchased key.

• Upgrade from Trial to Full License: Transitioning from a limited trial to a perpetual, legitimate license ensures unrestricted access.

• Correction of Activation Errors: Resolving errors due to typing mistakes, expired keys, or prior invalid activations.

• Compliance Adjustments: Businesses updating to volume or multi-user licensing for broader deployment.

• Reactivation after System Changes: Hardware replacements, system resets, or major updates may require key change for continued use.

Microsoft’s activation ecosystem is robust yet flexible—correct product key management keeps you secure, compliant, and eligible for support.

Pre-Change Checklist: Optimize for Success

Before you start, confirm these essentials for smooth product key update:

• Have Your Valid Product Key Ready: The new key must be 25 characters.

• Close All Office Applications: Ensure no Office apps are running to avoid data conflict.

• Connect to the Internet: Required for verification and online activation—preferably without VPN/proxy.

• Backup Important Documents: Safeguard your data before system changes.

• Run as Administrator: Particularly for advanced or multi-user deployments.

• Review Licensing Terms: Ensure the key matches Office 2024 Professional Plus and license agreement.

• Uninstall Previous Office Versions: Prevent conflicts by removing outdated editions.

A detailed pre-check removes nearly all friction from the activation process.

Step-by-Step Guide: Changing Product Key via Graphic Interface

1. Open Any Office Application
E.g., Word, Excel, or PowerPoint.

2. Navigate to Account Settings
Click File (top left), then Account.

3. Access Product Information
Locate “Product Information”—look for Change Product Key or Switch License.

4. Enter the New Product Key
Click Enter product key instead. If prompted to sign in, you may also select Use a different account.
Type in your new 25-character product key and follow the prompts to activate.

5. Confirm Activation
Office will verify the key. If accepted, you’ll see a confirmation message. Close and reopen your Office apps to finalize the change.

6. Troubleshooting Options
If you cannot see the “Change Product Key” option, update Office by selecting Update Options > Update Now from the Account menu.

7. Upgrade Confirmation
Check under File > Account for “Product Activated” or “Licensed” status.

This method is supported across Office 2024 LTSC Pro Plus, LTSC Standard, Home, and Home & Business.

Advanced Method: Change Product Key Using Command Prompt (CMD)

For IT administrators or power users, CMD offers granular control:

1. Run Command Prompt as Administrator
Windows Search → Type “cmd” → Right-click → “Run as administrator”.

2. Navigate to Office Installation Directory
For 64-bit systems:
cd "C:\Program Files\Microsoft Office\Office16"
For 32-bit or x64 systems:
cd "C:\Program Files (x86)\Microsoft Office\Office16"

3. Display Current Keys (Optional)
cscript ospp.vbs /dstatus

4. Uninstall Old Key
cscript ospp.vbs /unpkey:XXXXX (replace XXXXX with last 5 digits of old key)

5. Enter New Product Key
cscript ospp.vbs /inpkey:XXXXX-XXXXX-XXXXX-XXXXX-XXXXX

6. Activate Office
cscript ospp.vbs /act

7. Verify License Status
