Product key / licence key



The product key (licence key) for Windows is a 25-digit code which is required to activate Windows. This ensures that this version is not installed on more devices than specified in the Microsoft software licence conditions. In most cases, the product key is automatically stored and activated. If it is necessary to enter the product key, it can be found in the Windows confirmation email or in the delivery package of the Windows version.
