Change your Office product key

Most versions of Office 2024, Office 2021, and Office 2019 don’t include a product key and you only need to sign in with the account already linked to your Office license.

If your version did include a product key, follow the steps under the 2016 tab.

1. On the device where you want to change the key, open any Office app, select the File menu and then select Account near the bottom of the menu.

2. Under Product Information, select the Switch License button.

   If there is no Switch License button, you may need to install Office updates.

3. Do one of the following:

   • If you're signed in, select Use a different account, and then select Enter product key instead.

   • If you're not signed in, select Enter product key instead.

4. Enter your Office 2016 product key, and then select Install this product instead.

   If your product key is new, follow the prompts to complete the redemption process.

5. Office begins the update process. Close all Office apps to finish the process.

1. Sign in to your Subscriptions page with the email and password associated with the Microsoft account that was used to install Office.

   After you sign in, you should see a list of Office products that are associated with your Microsoft account.

2. For the first product that's listed on the page, select View product key. Copy or write down the product key. This is likely the product key that was used multiple times to install Office.

3. Select View product key for the remaining Office products and copy or write them down. These are likely the keys that you'll use to replace the key that was used multiple times.

4. On a PC where Office activation is failing, open the Command Prompt as described below:

   Select the Start button (lower-left corner). Type Command Prompt. Right-click the Command Prompt icon, and select Run as administrator.	Select the Start button (lower-left corner). Right-click Command Prompt and select Run as administrator.

   Tips: 

   • The default installation for Office is 32-bit but if your PC has more than 4 GB of RAM, you probably have 64-bit Windows.

   • If you don't know which Office version is installed, see What version of Office am I using? To check whether Windows is installed as 32 or 64 bits, see Which Windows operating system am I running?

6. Now start an Office app, such as Word, and select Next to activate Office over the Internet.

7. Repeat this process for each PC where activation is failing.
