For this edition to be installed successfully, the tablet PC must have a touchscreen device or tablet digitizer and a special control button for scrolling. Here are some of the unique features associated with this edition. There are two sub-editions of this OS released by Microsoft to support bit hardware. The former lost support from Microsoft in July after which no further security features updates were released for it.

However, the latter continued to thrive coming with different service packs. Each pack is an improvement on the earlier one as it contains one or more features the others does not have. In general, the bits editions have the unique advantage of increase in the maximum number of virtual memory that can be allocated. The two versions are also immune to certain viruses and malware that often attack bit systems. There are some devices such as ATMs, Cell Phones, thermostats and calculators with dedicated functions which are usually having real-time computing constraints.

These are the ones know as embedded systems. The edition, known as Microsoft Windows Embedded brings all of the features of XP Professional to these systems just with some few differences. Here are some of the features you get in XP Professional but which are absent in embedded. For all editions, the following system specifications will just be sufficient for installation.

Windows XP x64 can support much more memory; although the theoretical memory limit a bit computer can address is about 18 billion GB 18 exabytes , Windows XP x64 is currently limited to GB bytes of physical memory and 16 TB bytes of virtual memory. Microsoft claims this limit will be increased as hardware capabilities improve. In practice, most motherboards compatible with bit processors do not support nearly the maximum, and often retain the 4 GB limit.

Since the AMD64 architecture includes hardware-level support for bit instructions, WOW64 simply switches the process between and bit modes. However, on the IA architecture, WOW64 was required to translate bit x86 instructions into their bit IA equivalents which in some cases were implemented in quite different ways so that the processor could execute them.

As a result, AMD64 microprocessors suffer no performance loss when executing bit Windows applications, whereas IA implementations experience noticeable performance loss. Although bit applications can be run transparently, the mixing of the two types of code within the same process is not allowed. A bit application cannot link against a bit library DLL and similarly a bit application cannot link against a bit library.

This may lead to the need for library developers to provide both and bit binary versions of their libraries.
