ReactOS Adds First Windows NT6 System Call, Advancing Vista Compatibility

ReactOS has added its first Windows NT6 system call implementation. The new call is a core component of the Windows Vista API set. This development moves the open‑source OS closer to Vista compatibility. ReactOS aims to provide binary compatibility with Windows applications. The addition reflects ongoing progress on the project’s roadmap. It may enable more Vista‑era software to run on ReactOS. The milestone was reported by Phoronix. Future work will focus on expanding NT6 support further.
