Windows XP Professional Edition Upgrade x64 (Includes Software Assurance) (English/Multilanguage)
The x64 Edition of Windows XP Professional is designed to work with 64-bit processors from AMD and Intel that support the x64 extensions to the x86 architecture.
To install this operating system on your x64 computer, you must already have a valid license for one of the following operating systems (not necessarily on the x64 computer), and you must discontinue the use of that operating system: Windows 98, Windows 98 SE, Windows Me, Windows NT Workstation 4.0, Windows 2000 Professional, or Windows XP Home Edition.
Make a thorough backup of your important files before you install Windows XP Professional x64 Edition. The installation wipes out all data on the same drive as the operating system, so you will need to reinstall all your applications and restore all your files from backup.
The Windows XP Multilingual User Interface Pack is designed for multilingual work environments; it allows administrators or users to specify the language of the user interface as any of the 33 supported languages: German, French, Japanese, Simplified Chinese, Traditional Chinese, Korean, Arabic, Hebrew, Spanish, Italian, Swedish, Dutch, Brazilian, Norwegian, Danish, Finnish, Russian, Czech, Polish, Hungarian, Portuguese, Turkish, Greek, Slovak, Slovenian, Romanian, Croatian, Bulgarian, Estonian, Lithuanian, Latvian, or Thai.
Installing this product requires a licence key and installation media.

- Under the Software Assurance programme, customers acquire the right to install any new release of products covered in the agreement during the term of their coverage.
- Because x64 applications run natively, they run faster and more efficiently and can deliver more data per clock cycle.
- Support for up to 128 GB of RAM and 16 terabytes (TB) of virtual memory enables applications to preload substantially more data into virtual memory and to run faster when working with large data sets.
- The Windows on Windows 64 (WOW64) x86 emulation layer allows organizations to keep their existing investment in 32-bit software and Windows expertise.
- Performance and scalability are enhanced because the computer can have two single-core or multicore x64 processors.
- The 64-bit Windows environment is virtually identical to the development environment for 32-bit Windows.
