I’ve been looking for a free way to activate Advanced SystemCare Ultimate 16 Pro, and I found a guide offering the key for free. However, I’m not sure if it’s trustworthy or if it will work as promised. Has anyone used this key to activate their system?

Here’s the link to the guide: Advanced SystemCare 16 Key. Does this method provide a valid activation key, or should I consider other options? Is it a safe way to activate the software, or are there any risks involved?
