A member of the series, Windows XP, debuted on October 25, 2001, and became the first consumer-oriented version of Windows to not use DOS. Although Windows XP could emulate DOS, it could not run many of its applications as they ran only in real mode to directly access the computer's hardware, and Windows XP's protected mode prevented such ...
Windows Fundamentals for Legacy PCs is a Windows XP Embedded derivative and, as such, it requires significantly fewer system resources than the fully featured Windows XP. [4] It also features basic networking, extended peripheral support [clarification needed], DirectX, and the ability to launch the remote desktop clients from compact discs.
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).
PearPC only runs on x86 systems including Intel and AMD such as Windows, Linux, FreeBSD, and ReactOS. [9] [10] The emulator features a just-in-time (JIT) processor emulation core which dynamically translates PPC code into x86 code, caching the results.

Many 16-bit Windows legacy programs can run without changes on newer 32-bit editions of Windows. The reason designers made this possible was to allow software developers time to remedy their software during the industry transition from Windows 3.1 to Windows 95 and later, without restricting the ability for the operating system to be upgraded to a current version before all programs used by a ...
The first, Windows XP 64-Bit Edition, was intended for IA-64 systems; as IA-64 usage declined on workstations in favor of AMD's x86-64 architecture, the Itanium edition was discontinued in January 2005. [57] A new 64-bit edition supporting the x86-64 architecture, called Windows XP Professional x64 Edition, was released in April 2005. [58]
