MenuetOS is an operating system in development for PC, written fully in assembly language (64bit and 32bit). Features include pre-emptive and real-time multitasking with multiprocessor support and Graphical User Interface. Menuet64 is released under License and Menuet32 under GPL. Menuet supports both 64 and 32bit x86 assembly programming for much faster, smaller and less resource hungry applications.

Menuet isn't based on other operating system nor has it roots within UNIX or the POSIX standards. The design goal has been to remove the extra layers between different parts of an OS, which normally complicate programming and create bugs.

Menuet's application structure isn't specifically reserved for asm programming since the header can be produced with practically any other language. However, the overall application programming design is intended for 64/32 bit asm programming. Menuet programming is fast and easy to learn. Menuet's responsive GUI is easy to handle with assembly language. And Menuet64 is capable of running Menuet32 applications.
