Windows Vista Business 64-bit

Windows Vista, a major release of the Microsoft Windows operating system, was available in six different product editions: Starter, Home Basic, Home Premium, Business, Enterprise, and Ultimate. On September 5, 2006, Microsoft announced the USD pricing for editions available through retail channels. Editions sold at retail were available in both Full and Upgrade versions, and would later feature integration with Service Pack 1.

Microsoft characterized the packaging for the retail editions of Windows Vista as "designed to be user-friendly, […] a small, hard, plastic container designed to protect the software inside for life-long use." The packaging opens sideways to reveal the Windows Vista DVD suspended in a clear plastic case. The Windows Vista disc itself uses a holographic design similar to the discs that Microsoft has produced since Windows 98.

With the exception of Windows Vista Starter, all editions support both 32-bit (x86) and 64-bit (x64) processor architectures. Microsoft ceased retail copies of Windows Vista in October 2010.

Notes:

To support 64-bit platforms such as Intel Xeon, Intel Core 2, AMD Opteron and AMD Athlon 64, Microsoft released 64-bit versions of every edition of Windows Vista except for the Starter edition. These editions can run 32-bit programs by running them within the WOW64 subsystem. Most 32-bit programs can run natively, though applications that rely on device drivers will not run unless those device drivers have been written for 64-bit Windows. Reviewers have reported that the 64-bit editions of Windows Vista outperform their 32-bit counterparts in synthetic benchmarks such as PassMark.
