Simple Terms
By James Pearson-Harris
Each license that you acquire must be permanently assigned to a device. You may run the software in either a physical or virtual OSE on the licensed device.
Local use (on the licensed device) is permitted for any user. Remote use of the software is permitted for the Primary User of the licensed device. The Primary User is someone "who uses the device more than 50% of the time in any 90 day period." Remote use for any other user must be from as separately licensed device, or from a device with a Windows VDA license. Only one user may access and use the software at a time.
Another user can access the software at the same time, using Remote Assistance or similar technologies, solely to provide technical support. You may connect up to 20 devices to the Licensed Device for file sharing, printing, Internet Information Services, Internet Connection Sharing or telephony services.
