Your product key is different based on what version of Office you have. If the activation code or product key you have triggers a renewal window every time you open an Office application, you might need to update it or change it. Follow the steps in this guide to learn how.

Easily Change Office Key

If you have a subscription to Office 365 or use Office 2024, 2021, and 2019, you don't need a product key since it's attached to your Microsoft account.
With Office 2016, go to File > Account > Switch License and enter the new license or product key.
If an Office app isn't opening or giving you an activation or product code error message, use Command Prompt to change the active product key.

Get your product key for the malfunctioning product. Use this method if an installation of Office 2019-2016 on Windows is not opening.
- You can either get a new key or go to https://account.microsoft.com/services, look for the Office app that isn't working, click View product key, and copy it.
Search the Start menu for "Command Prompt," then right-click the app result and select Run as admin.

Enter the following code: cscript "C:\Program Files\Microsoft Office\Office16\OSPP.VBS" /dstatus (32-bit Windows) or cscript "C:\Program Files (x86)\Microsoft Office\Office16\OSPP.VBS" /dstatus (64-bit Windows) and press Enter.

Enter the following code: cscript "C:\Program Files\Microsoft Office\Office16\OSPP.VBS" /unpkey:XXXXX (32-bit Windows) or cscript "C:\Program Files (x86)\Microsoft Office\Office16\OSPP.VBS" /unpkey:XXXXX (64-bit Windows). Replace the XXXXX with the last 5 digits of the previous key and press Enter.
- This removes that key from your activated product.
cscript "C:\Program Files\Microsoft Office\Office16\OSPP.VBS" /inpkey:XXXXX-XXXXX-XXXXX-XXXXX-XXXXX (32-bit Windows) or cscript "C:\Program Files (x86)\Microsoft Office\Office16\OSPP.VBS" /inpkey:XXXXX-XXXXX-XXXXX-XXXXX-XXXXX (64-bit Windows). Replace XXXXX-XXXXX-XXXXX-XXXXX-XXXXX with your activation or product key and press Enter.
Since you removed a key and added a new one, you'll need to walk through the registration process again.^{[1]
