Tao ExDOS enables users of DOS applications to work with these applications on new operating systems. Using the built-in Virtual 8086 mode of the x86 CPU, Tao ExDOS enables DOS and 16-bit Windows applications (that run under DOS) to run effectively in 32-bit Windows desktop environments, including Windows 10/8/7/Vista/XP/2000 and Windows Terminal Server 2003/2008.

Virtual DOS machines can operate either exclusively through typical software emulation methods (e.g. dynamic recompilation) or can rely on the virtual 8086 mode of the Intel 80386 processor, which allows real mode 8086 software to run in a controlled environment by catching all operations which involve accessing protected hardware and forwarding them to the normal operating system (as exceptions).
