A screenshot showing how Wine can be configured to mimic different versions of Windows, going as far back as Windows 2.0 in the 32-bit version (64-bit Wine supports only 64-bit versions of Windows) There is the utility winecfg that starts a graphical user interface with controls for adjusting basic options.

QEMU has multiple operating modes: [7] User-mode emulation. In the user emulation mode, QEMU runs single Linux or Darwin/macOS programs that were compiled for a different instruction set. System calls are thunked for endianness and for 32/64-bit mismatches. Fast cross-compilation and cross-debugging are the main targets for user-mode emulation.
ReactOS 0.4.14 running the Firefox web browser. ReactOS is a free and open-source operating system for i586/amd64 personal computers intended to be binary-compatible with computer programs and device drivers developed for Windows Server 2003 and later versions of Microsoft Windows.
User-mode Linux (UML) is a virtualization system for the Linux operating system based on an architectural port of the Linux kernel to its own system call interface, which enables multiple virtual Linux kernel-based operating systems (known as guests) to run as an application within a normal Linux system (known as the host).
James Harper and the Xen open-source community have started developing free software paravirtualization drivers for Windows. These provide front-end drivers for the Xen block and network devices and allow much higher disk and network performance for Windows systems running in HVM mode. Without these drivers all disk and network traffic has to ...
Windows 10 includes WDDM 2.0, which is designed to dramatically reduce workload on the kernel-mode driver for GPUs that support virtual memory addressing, [37] to allow multithreading parallelism in the user-mode driver and result in lower CPU utilization.
User-Mode Driver Framework (UMDF) is a device-driver development platform first introduced with Microsoft's Windows Vista operating system, and is also available for Windows XP. It facilitates the creation of drivers for certain classes of devices.
Graphics device drivers are implemented using two components: a UMD (user-mode driver) and a KMD (kernel-mode driver). Starting with Linux kernel 4.2 AMD Catalyst and Mesa will share the same Linux kernel driver: amdgpu. Amdgpu provides interfaces defined by DRM and KMS.
