Identifying whether your software was activated using KMS Pico can be challenging. However, there are a few signs to look for: if your software periodically prompts for reactivation or displays warning messages about activation issues, it might be a sign of using unauthorized tools. Additionally, running specific system commands, like `slmgr /xpr` in the Command Prompt for Windows, can show if the activation status is tied to a KMS server. For Office, you can check the activation status through the application’s account settings or by using command-line tools.
