After using KMSpico, you can check the activation status of your Microsoft product by going to the product’s settings. For Windows, navigate to Settings > Update & Security > Activation. For Office, open any Office application and go to File > Account. If the product is activated, you will see a message indicating that it is activated. However, because KMSpico’s activation can sometimes be unreliable, it is a good practice to regularly check the activation status and be prepared for potential deactivation issues.
