How can I verify if the Windows operating system I am using is genuine or pirated?

To verify if the Windows system being used is genuine, the following methods can be taken:

1. Activation status check: Open Windows settings, click on Update & Security, select Activation, and check its activation status. If it shows as activated, it is likely a genuine system.
2. Activate the key verification: In Windows settings, click on Update & Security, select Activation, click on Change Product Key, and enter the activation key provided by the system for verification. If the key is accepted and activation is successful, it is a genuine system.
3. Official verification tool: Microsoft provides an official Windows validation tool that you can download and run to authenticate the legitimacy of your system. This tool will check the system activation status and other key information to determine if the system is legal.
4. Purchase confirmation: If you bought your Windows system through legitimate channels such as the official Microsoft website or an authorized retailer, then chances are you are using a genuine system.
5. Activation method check: If the system was activated through cracking tools or illegal methods, it is likely a pirated system. Legitimate systems are usually activated through a valid product key.

In general, the most reliable way to ensure that your Windows system is genuine is by purchasing a genuine version and using a legal activation method.
