In computing, a page fault is an exception that the memory management unit (MMU) raises when a process accesses a memory page without proper preparations. Accessing the page requires a mapping to be added to the process's virtual address space.
Includes enhanced support for Non-Uniform Memory Access (NUMA) and systems with large memory pages. Windows Vista also exposes APIs for accessing the NUMA features. Memory pages can be marked as read-only, to prevent data corruption. New address mapping scheme called Rotate Virtual Address Descriptors (VAD). It is used for the advanced Video ...
Windows Vista contains a range of new technologies and features that are intended to help network administrators and power users better manage their systems. Notable changes include a complete replacement of both the Windows Setup and the Windows startup processes, completely rewritten deployment mechanisms, new diagnostic and health monitoring tools such as random access memory diagnostic ...
When using two display adapters, both must use the same WDDM driver. Although Windows Vista still supports XPDM drivers, a WDDM driver is required for the Windows Aero user experience. [54] [55] Windows Vista restricts the amount of memory DPMI programs can have to 32 MB (33,554,432 bytes).
In operating systems, memory management is the function responsible for managing the computer's primary memory. [1]: 105–208 The memory management function keeps track of the status of each memory location, either allocated or free. It determines how memory is allocated among competing processes, deciding which gets memory, when they receive ...
In computer operating systems, memory paging is a memory management scheme that eliminates the need for contiguous memory allocation. [1]It is often combined with the related technique of allocating and freeing page frames and storing pages on and retrieving them from secondary storage [a] in order to allow the aggregate size of the address spaces to exceed the physical memory of the system.

Direct3D 9 in Windows Vista is called Direct3D 9Ex and also uses the WDDM, which allows Direct3D applications to access new features available in Windows Vista including advanced gamma functions, cross-process shared surfaces, device removal management, managed graphics memory, prioritization of resources, and text anti-aliasing.
Windows Vista introduces the ability to independently redirect up to 10 user profile sub-folders to a network location. [20] There is also a Management Console snap-in in Windows Vista to allow users to configure Folder Redirection for clients running Windows Vista, Windows XP, and Windows 2000.
