I’ve been considering using a Microsoft 365 product key for activating Advanced SystemCare Ultimate 16 Pro. Has anyone here used this key for software other than Office, like SystemCare? Does it work as expected, or are there issues with using a Microsoft 365 key for third-party software?

Here’s the link to the key: https://productkeysbuzz.co/microsoft-office-365-product-keys-activation-method/. Does this key work for activating SystemCare, or is there another key I should be looking for?
