Is internet connectivity required for product activation?

Yes, internet connectivity is generally required for product activation. When activating a Microsoft product, such as Windows or Office, online activation is the most convenient and commonly used method. This allows the system to connect with Microsoft servers to validate and activate the product using a unique product key. Internet connectivity enables the software to verify the authenticity of the key and ensure it has not been used on multiple devices. However, there may be alternative methods available for activation in cases where internet access is limited or unavailable. For instance, offline activation methods such as phone activation may be provided by Microsoft. It is advised to refer to the specific product activation guidelines or contact Microsoft's Activation Support for further assistance or alternative activation options if internet connectivity is an issue.
