A business desktop is designed with a specific purpose in mind - it's used by businesses to work on their projects and carry out their day-to-day tasks. A regular desktop is a personal computer that can be used for anything, from browsing the internet to playing games. 

While a business desktop is designed with specific features in mind, regular desktops have more general functions. For example, a regular desktop can be used for office work, surfing the internet, and working on projects. Business desktops are often faster and more powerful than regular desktops, making them better suited for tasks like editing video or compiling data. 

One of the main differences between business desktops and regular desktops is that business desktops usually come with additional software tools and applications to help you get started quickly.
