KMSPico is designed to work with several versions of Windows and Microsoft Office, including both older and newer releases. It works by creating a virtual KMS server on your computer, which then provides activation tokens to the Microsoft software, making it appear as if it is properly licensed. This process is typically used for testing and evaluation purposes. However, due to the nature of KMSPico, using it to bypass legitimate activation requirements can result in unstable software performance and potential legal issues. For reliable and legal activation, it is recommended to use official Microsoft methods.
