There could be multiple desktops and configurations of the same workspace and username in Windows, such as having a work workspace, and a school workspace, and a personal workspace - to adequately and organizationally separate them out into different purposes. It could also be possible for someone that runs a big company to have different views for different purposes of the company, such as Accounting, Marketing, and Legal. Each of the different purposes of the work space would be separated, and settings and data could be shared and/or compartmentalized, to help to organize multiple purposes on the same computer, without having to create separate user accounts.
