Yes, there are significant risks involved in using an Office activator. Firstly, it can lead to legal consequences as it violates Microsoft’s terms of service. Additionally, many activators are known to contain malware or spyware, which can compromise your system’s security and lead to data loss. Furthermore, using these tools may prevent you from receiving updates and support from Microsoft, leaving your software vulnerable to security exploits. It’s always best to opt for legitimate licensing options to ensure software integrity and security.
