+# RustDesk server Pro on Windows server is deprecated
+
+The executable (`hbbs`/`hbbr`) is still maintained. We marked it as deprecated only because our support team lacks experience with Windows Server, which means we cannot provide effective assistance if you encounter any environment-related issues on Windows Server. If you are proficient with Windows Server, you can continue using it. Otherwise, we recommend switching to Linux for better support.
