Windows - Microsoft Desktop Operating System
The current version of Windows, like the previous ones, is licensed for the copy and for the device: you must purchase a license for each device that is accessed or used by the product locally or remotely. As a rule, one license provides the right to install one copy of the product on one device. Before buying licenses, read the Windows Desktop Licensing Rules and read the Windows Desktop Licensing FAQ.
