The method depends on what type of Office licence you have, are you experiencing activation errors after the upgrade?

2

Click your Start Button, type cmd then right click Command Prompt and choose 'Run as Administrator'

Run or paste this command and hit Enter:

slmgr.vbs /dlv

Please post a screenshot of the resulting dialog

3

Download the free ShowKeyPlus app from the Microsoft Store.

Please provide a screenshot of that app window and please hide your product key in the screenshot.

    To find your Windows 11 product key after upgrading from Windows 10, you can use the following methods:

    1. Using Command Prompt:
      • Open Command Prompt as an administrator.
      • Type the command: wmic path softwarelicensingservice get OA3xOriginalProductKey and press Enter. This should display your product key if it is available.
    2. Using Windows Settings:
      • Go to Settings > Update & Security > Activation. If your Windows is activated, you may see the product key listed there.
    3. Using a Third-Party Tool:
      • There are various third-party tools available that can retrieve your product key from the registry. Tools like ProduKey or Magical Jelly Bean Keyfinder can be used for this purpose.
    4. Check Microsoft Account:
      • If you linked your Microsoft account with your Windows 10 installation, you might find your product key in your Microsoft account under the devices section.

    Keep in mind that if you upgraded from Windows 10 to Windows 11, your original Windows 10 key is likely still valid and will be used for activation unless you have changed your hardware significantly (like a motherboard).

    If you upgrade from Windows 10 to Windows 11 as a free upgrade, you'd have 'digital entitlement'. Which means, your license is tied to your Microsoft account. Sign in with your Microsoft account, you device will be activated.
