A retail license for Windows Server 2022 Standard is a single, transferable license for one device that can be purchased from a retailer and is valid for a lifetime. This type of license is associated with an individual key for online activation, providing official updates and supporting both 32-bit and 64-bit systems. Unlike an OEM license that comes pre-installed with a device, a retail license is transferable to new hardware but can only be installed on one device at a time.
