All 64-bit versions of Microsoft operating systems impose a 16 TB limit on address space. Processes created on the 64-bit editions of Windows Vista can have 8 TB in virtual memory for user processes and 8 TB for kernel processes to create a virtual memory of 16 TB. [48]
A 64-bit processor performs best with 64-bit software. A 64-bit processor may have backward compatibility, allowing it to run 32-bit application software for the 32-bit version of its instruction set, and may also support running 32-bit operating systems for the 32-bit version of its instruction set. A 32-bit processor is incompatible with 64 ...
Microsoft Windows is a computer operating system developed by Microsoft. It was first launched in 1985 as a graphical operating system built on MS-DOS. The initial version was followed by several subsequent releases, and by the early 1990s, the Windows line had split into two separate lines of releases: Windows 9x for consumers and Windows NT ...
The 64-bit variant runs on CPUs compatible with the 8th generation of x86 (known as x86-64, or x64) or newer, and can run 32-bit and 64-bit programs. 32-bit programs and operating system are restricted to supporting only 4 gigabytes of memory, while 64-bit systems can theoretically support 2048 gigabytes of memory.

Many features were eventually reimplemented after the reset, but Microsoft ceased using managed code to develop the operating system. [8] New features of Windows Vista include a graphical user interface and visual style referred to as Windows Aero; a content index and desktop search platform called Windows Search; new peer-to-peer technologies ...
As with Windows XP Professional x64 Edition, in Windows Vista x64, old 16-bit Windows programs are not supported. If 16-bit software needs to be run in 64-bit Windows Vista, virtualization can be used for running a 32-bit operating system.
