Bochs 2.7
Emulate an x86 PC for legacy softwareBochs emulates an x86 PC, including its processor, memory, BIOS and common I/O devices, so operating systems and applications can run inside a virtual machine. It supports guests such as DOS, Linux and older Windows releases. Users can configure the emulated CPU and hardware for testing legacy software, exploring system behavior or running a separate PC environment. The Windows edition is freeware.

Bochs for Windows 10 - Full description
Bochs is a portable emulator that recreates an x86 personal computer in software. It is suited to developers, testers and users who need to run older operating systems or applications in a separate virtual machine, without relying on a physical PC with matching hardware. The emulator models the processor, memory, BIOS and common input/output devices so a guest system can boot and run within a window on the host computer.
A Bochs configuration defines the hardware presented to the guest, including the processor model and device setup. Depending on the build, the emulated CPU can represent systems ranging from 386-class PCs through later Pentium models and x86-64, with optional instruction-set extensions. The virtual machine's BIOS and emulated devices provide the basic environment an operating system needs to start, interact with storage and other hardware, and run software. This makes Bochs useful for reproducing older PC configurations as well as experimenting with different system setups.
The emulator can run a range of guest operating systems, including DOS, Linux, Windows 95 and 98, and Windows NT, 2000, XP and Vista. Once installed in the emulated PC, guest applications run as though they were on that system, while Bochs displays the simulated machine on the host desktop. This separation is useful for checking compatibility, exploring legacy software, testing operating-system behavior, and learning how PC hardware and boot processes work.
Bochs is written in C++ and is designed to be portable across operating systems. Its open-source codebase supports builds with different emulation modes, though the available modes depend on how the program is compiled. The Windows edition is freeware and is intended for 32-bit x86 PC emulation; performance and guest compatibility depend on the host system, configuration and guest software. Bochs emulates hardware rather than providing a guest operating system, so users need suitable operating-system installation media and any required licenses for the software they run.
