Question about RTX3070 I7 SE - 563213

Hi, in the description of the product it says that the operating system is Windows 11 Home. Does this mean that the product comes with Windows already installed? Or does it come with the product key for Windows and the customer has to install it themselves? Moreover, one of the questions above (23 days ago) implied that Windows was not included, and the answer to that question indicated that the deployment and installation service (about 50 CHF) was not included. Hence, I'm not sure if I should interpret this to mean that for 50 CHF Digitech installs and provides Windows, or that the Windows key is included in the price but Digitech does not install it unless one pays for this 50 CHF service? Thank you for the clarification and have a nice day! Matt
