I found a Microsoft Office 365 product key free guide, and I’m considering using it to activate Advanced SystemCare Ultimate 16 Pro. Before proceeding, I want to check if anyone has used this method and if it’s safe. Are there any potential risks or issues with using a Microsoft Office key for activating SystemCare?

Here’s the link to the guide: Microsoft Office 365 Product Key. Is this a trustworthy activation method, or should I explore other options?
