MenuetOS was originally written for 32-bit x86 architectures and released under the GPL-2.0-only license, thus many of its applications are distributed under the GPL.[2]
64-bit
The 64-bit MenuetOS, often referred to as Menuet 64, remains a platform for learning 64-bit assembly language programming. The 64-bit Menuet is distributed without charge for personal and educational use only, but without the source code, and the license includes a clause that prohibits disassembly.[1]
MenuetOS development has focused on fast, simple, efficient implementation. MenuetOS has networking abilities, and a working TCP/IP stack. Most of the networking code is written by Mike Hibbett.
The main focus of Menuet has been on making an environment for easy assembly programming, but it is still possible to run software written in high-level programming languages on the assembler core. The biggest single effort towards high-level language support is Jarek Pelczar's work in porting C libraries to Menuet.

64-bit
The 64-bit main distribution is now proprietary. Several distributions of the 32-bit GPL MenuetOS still exist, including translations in Russian, Chinese, Czech, and Serbian.
