Windows Fundamentals for Legacy PCs ("WINFLP"), codenamed "Edgar", is a thin client operating system released by Microsoft on July 8, 2006. It is a version of Windows XP that is made for older and less powerful hardware. Windows Fundamentals is not marked as a full-fledged general purpose operating system, though it is functionally able to perform most of the tasks generally associated with one. It includes only certain functionality for local workloads, such as security, management, the .NET framework, and document viewing related tasks. It is designed to work as a client-server solution with RDP clients or other third party clients.
