Windows XP Pro 64 has attracted little interest among manufacturers,
developers and users.
With the flop of Windows XP Pro 64-bit, users ask more questions about Windows Vista. Because if many manufacturers believe that Windows Vista 64-bit is the future, availability too low 64-bit applications is an important consideration. As yet, a platform 64-bit Windows Vista is only useful if you plan to use your PC for "professional". Or even as a mere amateur or user to perform editing professional quality video, creating 3D (images, etc..), Subject to finding adequate and applications optimized for 64 bits.

Although it is still possible to use its usual applications pending an update or a new version optimized for 64 bits. Since Microsoft has developed 32-bit Windows on Windows 64 bit (WOW64), a sub-system in the x64 versions XP, 2003 x64 and Windows Vista x64 running at startup, and to run most of the 32-bit applications (16-bit applications are no longer supported) in a 64-bit.
Provided that these applications do not install modules or core unsigned drivers. The Kernel Patch Protection technology found only in 64-bit versions of Windows, requiring the installation of 64-bit drivers signed by Microsoft.
You should therefore make a very strict attention to the availability of 64-bit drivers for your components and peripherals.
