xEMU for Windows is a

high-performance x86 emulator

designed to run a wide range of x86 applications on Windows. Unlike some emulators which focus on specific applications or operating systems, xEMU aims for broad compatibility. It uses dynamic binary translation to run x86 code, which generally means faster execution than full system emulation. However, it[SQ]s still an emulator, so performance will never match native execution speed. Its intended purpose is to run legacy software or applications not natively supported by Windows.
