Only 64-bit drivers are supported in Windows XP 圆4 Edition, but 32-bit codecs are supported as long as the media player that uses them is 32-bit. Windows XP 圆4 Edition also includes both 32-bit and 64-bit versions of Internet Explorer 6, so that user can still use browser extensions or ActiveX controls that are not available in 64-bit versions. The 32-bit version can become the default Windows Shell. Windows XP 圆4 Edition ships with both 32-bit and 64-bit versions of Windows Explorer. Specifically, 32-bit shell extensions for Windows Explorer fail to work with 64-bit Windows Explorer. This may lead to the need for library developers to provide both 32-bit and 64-bit binary versions of their libraries. A 64-bit program cannot use a 32-bit dynamic-link library (DLL) and similarly a 32-bit program cannot use a 64-bit DLL.

All 32-bit processes are shown with *32 in the task manager, while 64-bit processes have no extra text present.Īlthough 32-bit applications can be run transparently, the mixing of the two types of code within the same process is not allowed. On the Itanium architecture, WoW64 was required to translate 32-bit x86 instructions into their 64-bit Itanium equivalents-which in some cases were implemented in quite different ways-so that the processor could execute them. As a result, x86-64 architecture microprocessors suffer no performance loss when executing 32-bit Windows applications. Since the x86-64 architecture includes hardware-level support for 32-bit instructions, WoW64 simply switches the process between 32- and 64-bit modes. Later, it was adopted for 圆4 editions of Windows XP and Windows Server 2003. It was first used in Windows XP 64-bit Edition (for Itanium architecture).

Windows XP Professional 圆4 Edition uses a technology named Windows-on-Windows 64-bit (WoW64), which permits the execution of 32-bit software. Files and Settings Transfer Wizard supports migrating settings from both 32-bit and 64-bit Windows XP PCs.Remote Desktop Services supports Unicode keyboard input, client-side time-zone redirection, GDI+ rendering primitives for improved performance, FIPS encryption, fallback printer driver, auto-reconnect and new Group Policy settings.Benefits from Shadow Copy features introduced in Windows Server 2003.Benefits from IPsec features and improvements made in Windows Server 2003.

Windows XP Professional shipped with WMP 8 (with WMP 9 shipping with Service Pack 2 and later), although WMP 11 is available for Windows XP Service Pack 2 or later.

Ships with Windows Media Player (WMP) version 10.

All other 32-bit editions of Windows XP have IIS v5.1.

Ships with Internet Information Services (IIS) version 6.0.

Allows faster encoding of audio or video, higher performance video gaming and faster 3D rendering in software optimized for 64-bit hardware.

Supports GPT-partitioned disks for data volumes (but not bootable volumes) after SP1, which allows disks greater than 2 TB to be used as a single GPT partition for storing data.

Windows XP Professional 圆4 Edition also introduces Kernel Patch Protection (also known as PatchGuard) which can help improve security by helping to eliminate rootkits.

Uses the Windows Server 2003 kernel which is newer than 32-bit Windows XP and has improvements to enhance scalability.

As such, as of 2014, the OS supports all commercially available multicore CPUs, including Intel Core series, or AMD FX series.

Supports up to two physical CPUs (in separate physical sockets) and up to 64 logical processors (i.e.

During the initial development phases, Windows XP Professional 圆4 Edition was named Windows XP 64-Bit Edition for 64-Bit Extended Systems. Windows XP Professional 圆4 Edition is not to be confused with Windows XP 64-Bit Edition as the latter was designed for Itanium architecture. However, it includes client features of Windows XP such as System Restore, Windows Messenger, Fast User Switching, Welcome Screen, Security Center and games, which Windows Server 2003 does not have. Windows XP Professional 圆4 Edition uses the same kernel and code tree as Windows Server 2003 and is serviced by the same service packs. Although the theoretical memory limit of a 64-bit computer is about 16 exabytes (17.1 billion gigabytes), Windows XP 圆4 is limited to 128 GB of physical memory and 16 terabytes of virtual memory. 32-bit editions of Windows XP are limited to a total of 4 gigabytes. The primary benefit of moving to 64-bit is the increase in the maximum allocatable random-access memory (RAM).

It is designed to use the expanded 64-bit memory address space provided by the x86-64 architecture. Microsoft Windows XP Professional 圆4 Edition, released on April 25, 2005, is an edition of Windows XP for x86-64 personal computers.
