The clean-room Windows — a free reimplementation of the NT API that has been 'alpha' for a quarter century and still compiles drivers.

ReactOS (1996) is the open-source Windows-compatible OS — a clean-room NT-compatible kernel+userland that runs unmodified Windows drivers and applications. Started as FreeWin95, reborn as a binary-compatible NT clone.\n\nIt's the only serious attempt at an open Windows; still alpha, still aiming.
