Using KMS Pico for activation carries several risks. Firstly, it can violate the terms of service of Microsoft products, which might lead to legal consequences. Additionally, downloading and using such tools from unverified sources can expose your computer to malware, viruses, or other security threats. Furthermore, software activated with KMS Pico might not receive updates or support from Microsoft, which could lead to instability or other issues. It’s important to consider these risks and evaluate whether the benefits outweigh the potential downsides.
