Windows Thin PC

Windows Thin PC is the successor to Windows Fundamentals for Legacy PCs. It is based on Windows Embedded POSReady 7, a lightweight version of Windows 7 intended for point-of-sale devices, and serves as a thin client which can be used on older computers for users who do not want or do not have the option to upgrade hardware. It was released to manufacturing on 1 June 2011 and reached general availability on 1 July 2011.

The operating system is not available in the retail market and is only attainable from the Microsoft Software Assurance program, which is targeted towards the enterprise market.
