@Tyrone Miljo, Thanks for posting in Q&A. Regarding your first question, no, Windows 365 is a cloud-based service that creates virtual machines in the Microsoft cloud, which allows users to access their Cloud PC using any compatible device including laptops, desktops, tablets, or mobile phones. Users can access the operating system, applications, and data via the internet, which eliminates the need for a physical computer that would perform these tasks.
For your second question, no, you don't need 300 computers or devices to use the 300 licenses. Windows 365 Business provides a cloud-based PC without the need to manage any hardware, such as servers or end-user terminals. Windows 365 Business users can access their Cloud PC using any compatible device with a supported operating system and internet connectivity. Namely, you can have up to 300 unique users with access to the service.

Regarding your third question, no, virtual machines or cloud-based services do not perform the processing on the user's device. They utilize remote data centers to perform the processing, requiring an internet connection. The processing power of the computer involved in running the remote desktop service will determine the performance of Windows 365 and the application running within. Clients that do not require high power processing capability can still run smoothly on less powerful devices.
