{{Windows Vista}}
[[Windows Vista]] (formerly codenamed Windows "Longhorn") has many significant new features compared with previous [[Microsoft Windows]] versions, covering most aspects of the operating system.
Line 8 ⟶ 9:
For graphics, Windows Vista introduces a new as well as major revisions to [[Direct3D]]. The [[Windows Display Driver Model|new display driver model]] facilitates the new [[Desktop Window Manager]], which provides the [[page tearing|tearing]]-free desktop and special effects that are the cornerstones of the [[Windows Aero]] [[graphical user interface]]. The new display driver model is also able to offload rudimentary tasks to the [[GPU]], allow users to install drivers without requiring a system reboot, and seamlessly recover from rare driver errors due to illegal application behavior.
At the core of the operating system, many improvements have been made to the memory manager, process scheduler, heap manager, and [[
==Audio==
Windows Vista features a completely re-written audio stack designed to provide low-latency 32-bit floating point audio, higher-quality digital signal processing, bit-for-bit sample level accuracy, up to 144 dB of dynamic range and new audio [[

===Other audio enhancements===
* A new set of user interface sounds have been introduced, including a new startup sound
* The new Volume Mixer displays a percentage value showing the current system volume while the volume level is being changed. Previous versions of Windows only displayed a volume meter.
* Windows Vista also allows controlling system-wide volume or volume of individual audio devices and individual applications separately.<ref name="AudioImprovements"/><ref name="Softpedia">{{cite web |url=http://archive.news.softpedia.com/news/The-Windows-Vista-Volume-Mixer-41882.shtml |title=The Windows Vista Volume Mixer |last=Oiaga |first=Marius |date=December 7, 2006 |publisher=[[Softpedia]] |access-date=April 25, 2015 |archive-url=https://web.archive.org/web/20150214074429/http://archive.news.softpedia.com/news/The-Windows-Vista-Volume-Mixer-41882.shtml |archive-date=February 14, 2015 |url-status=dead |df=mdy-all }}</ref> This feature can be used from the new ''Volume Control'' windows or programmatically using the overhauled audio API. Different sounds can be redirected to different audio devices as well.

Microsoft has also included a new high quality voice capture [[DirectX]] Media Object (DMO) as part of [[DirectShow]] that allows voice capture applications such as [[
===Speech recognition===
Line 86 ⟶ 88:
Windows Vista is the first Windows operating system to include fully integrated support for [[speech recognition]]. Under Windows 2000 and XP, Speech Recognition was installed with Office 2003, or was included in Windows XP Tablet PC Edition.
Windows Vista includes speech recognition for 8 languages at release time: English (U.S. and British), Spanish, German, French, Japanese and Chinese (traditional and simplified). Support for additional languages is planned for post-release.

===XPS print path===
{{see also|XML Paper Specification}}
The XPS Print Path introduced in Windows Vista supports high quality 16-bit color printing.<ref>{{Cite web |url=http://blogs.msdn.com/b/adrianford/archive/2008/10/22/16-bits-and-more-printing-on-windows.aspx |title=16 bits and more printing on Windows |access-date=2010-06-22 |archive-date=2012-01-15 |archive-url=https://web.archive.org/web/20120115155328/http://blogs.msdn.com/b/adrianford/archive/2008/10/22/16-bits-and-more-printing-on-windows.aspx |url-status=live }}</ref> The XPS print path uses [[XML Paper Specification]] (XPS) as the [[

Line 129 ⟶ 131:
The XPS print path can automatically calibrate [[color profile]] settings with those being used by the display subsystem. Conversely, XPS print drivers can express the configurable capabilities of the printer, by virtue of the ''XPS PrintCapabilities'' [[Class (computer science)|class]], to enable more fine-grained control of print settings, tuned to the individual printing device.
Applications which use the [[Windows Presentation Foundation]] for the display elements can directly print to the XPS print path without the need for image or colorspace conversion. The XPS format used in the spool file, represents advanced graphics effects such as 3D images, glow effects, and gradients as Windows Presentation Foundation primitives, which are processed by the printer drivers without [[

}}</ref> It includes a native implementation of [[IPv6]], as well as complete overhaul of [[IPv4]]. IPv6 is now supported by all networking components, services, and the user interface. In IPv6 mode, Windows Vista can use the Link Local Multicast Name Resolution ([[LLMNR]]) protocol to resolve names of local hosts on a network which does not have a [[DNS server]] running. The new TCP/IP stack uses a new method to store configuration settings that enables more dynamic control and does not require a computer restart after settings are changed. The new stack is also based on a strong [[
The user interface for configuring, troubleshooting and working with network connections has changed significantly from prior versions of Windows as well. Users can make use of the new "Network Center" to see the status of their network connections, and to access every aspect of configuration. The network can be browsed using ''Network Explorer'', which replaces [[Windows XP|Windows XP's]] "[[My Network Places]]". Network Explorer items can be a shared device such as a scanner, or a file share. ''Network Location Awareness'' uniquely identifies each network and exposes the network's attributes and connectivity type. Windows Vista graphically presents how different devices are connected over a network in the ''Network Map'' view, using the [[
Support for [[Wireless LAN|wireless networks]] is built into the network stack itself, and does not emulate wired connections, as was the case with previous versions of Windows. This allows implementation of wireless-specific features such as larger frame sizes and optimized error recovery procedures. Windows Vista uses various techniques like [[RWIN|Receive Window]] Auto-scaling, [[Explicit Congestion Notification]], TCP Chimney offload and Compound TCP to improve networking performance. [[Quality of service]] (QoS) policies can be used to prioritize network traffic, with [[traffic shaping]] available to all applications, even those that do not explicitly use QoS APIs. Windows Vista includes in-built support for peer-to-peer networks and [[Server Message Block|SMB]] 2.0. For improved network security, Windows Vista supports for 256-bit and 384-bit [[Diffie-Hellman]] (DH) algorithms, as well as for 128-bit, 192-bit and 256-bit [[Advanced Encryption Standard]] (AES) is included in the [[network stack]] itself, while integrating [[IPsec]] with [[Windows Firewall]].

* The memory manager and processes scheduler have been improved. The scheduler was modified to use the cycle counter register of modern processors to keep track of exactly how many [[
* Windows Vista includes support for [[condition variable]]s and [[reader-writer lock]]s.
* Process creation overhead is reduced by significant improvements to DLL address-resolving schemes.
Line 173 ⟶ 175:
* ''Threaded DPC'' [https://web.archive.org/web/20090424065603/http://msdn.microsoft.com/en-us/library/ms795178.aspx], conversely to an ordinary DPC (Deferred Procedure Call), decreases the system latency improving the performance of time-sensitive applications, such as audio or video playback.
* Data Redirection: Also known as ''data virtualization'', this virtualizes the [[Windows Registry|registry]] and certain parts of the file system for applications running in the [[Principle of least privilege|protected user context]] if [[User Account Control]] is turned on, enabling legacy applications to run in non-administrator accounts. It automatically creates private copies of files that an application can use when it does not have permission to access the original files. This facilitates stronger file security and helps applications not written with the [[least user access]] principle in mind to run under stronger restrictions. ''Registry virtualization'' isolates write operations that have a global impact to a per-user ___location. Reads and writes in the {{mono|HKLM\Software}} section of the [[Windows Registry|Registry]] by user-mode applications while running as a standard user, as well as to folders such as "Program Files", are "redirected" to the user's profile. The process of reading and writing on the profile data and not on the application-intended ___location is completely transparent to the application.
* Windows Vista supports the [[PCI Express]] 1.1 specification, including PCI Express
* Native support and generic driver for [[Advanced Host Controller Interface]] (AHCI) specification for [[Serial ATA]] drives, SATA [[Native Command Queuing]], [[
* Full support for the [[
* [[Windows Vista SP1]] supports [[Windows Hardware Error Architecture]] (WHEA).
* Kernel-mode [[Plug-And-Play]] enhancements include support for PCI multilevel rebalance, partial arbitration of resources to support PCI subtractive bridges, asynchronous device start and enumeration operations to speed system startup, support for setting and retrieving custom properties on a device, an enhanced ejection API to allow the caller to determine if and when a device has been successfully ejected, and diagnostic tracing to facilitate improved reliability.<ref>{{Cite web |url=http://www.microsoft.com/whdc/system/pnppwr/pnp/default.mspx |title=Plug and Play: Architecture and Driver Support |website=[[Microsoft]] |access-date=2007-05-26 |archive-url=https://web.archive.org/web/20040616023120/http://www.microsoft.com/whdc/system/pnppwr/pnp/default.mspx |archive-date=2004-06-16 |url-status=dead }}</ref>
* The [[Windows Vista Startup Process|startup process for Windows Vista]] has changed completely in comparison to earlier versions of Windows. The [[NTLDR]] boot loader has been replaced by a more flexible system, with NTLDR's functionality split between two new components: [[winload.exe]] and [[Windows Boot Manager]].<ref name="bcd-faq">See [http://www.microsoft.com/technet/windowsvista/library/85cd5efe-c349-427c-b035-c2719d4af778.mspx Boot Configuration Data Editor Frequently Asked Questions] {{Webarchive|url=https://web.archive.org/web/20061208002701/http://www.microsoft.com/technet/windowsvista/library/85cd5efe-c349-427c-b035-c2719d4af778.mspx |date=2006-12-08 }} for details on BCD.</ref> A notable change is that the Windows Boot Manager is invoked by pressing the [[space bar]] instead of the F8 [[function key]].<ref>{{Cite web |url=http://blogs.msdn.com/windowsvistanow/archive/2008/12/05/the-space-bar-is-the-new-f8-when-it-comes-to-vista-and-server-2008-boot-options.aspx |title=The space bar is the new F8 when it comes to Vista and Server 2008 boot options |access-date=2010-05-18 |archive-date=2009-05-24 |archive-url=https://web.archive.org/web/20090524094408/http://blogs.msdn.com/windowsvistanow/archive/2008/12/05/the-space-bar-is-the-new-f8-when-it-comes-to-vista-and-server-2008-boot-options.aspx |url-status=live }}</ref> The F8 key still remains assigned for advanced boot options once the Windows Boot Manager menu appears.

* Windows Vista includes a completely overhauled and rewritten ''Event logging'' subsystem, known as [[Windows Event Log]] which is [[XML]]-based and allows applications to more precisely log events, offers better views, filtering and categorization by criteria, automatic log forwarding, centrally logging and managing events from a single computer and remote access.
* Windows Vista includes an overhauled [[Task Scheduler]] that uses hierarchical folders of tasks. The Task Scheduler can run programs, send email, or display a message. The Task Scheduler can also now be triggered by an [[XPath]] expression for filtering events from the ''Windows Event Log'', and can respond to a workstation's lock or unlock, and as well as the connection or disconnection to the machine from a ''Remote Desktop''. The Task Scheduler tasks can be scripted in [[VBScript]], [[JScript]], or [[
* ''Restart Manager'': The ''Restart Manager'' works with Microsoft's update tools and websites to detect processes that have files in use and to gracefully stop and restart services to reduce the number of reboots required after applying updates as far as possible for higher levels of the software stack. Kernel updates, logically, still require the system to be restarted.<ref>{{cite web | url=http://msdn.microsoft.com/en-us/library/aa373654.aspx | title=Restart Manager | author=Microsoft | publisher=Microsoft | work=MSDN Library | access-date=2008-12-21 | archive-url=https://web.archive.org/web/20090112123045/http://msdn.microsoft.com/en-us/library/aa373654.aspx | archive-date=2009-01-12 | url-status=dead }}</ref> In addition, the Restart Manager provides a mechanism for applications to stop and then restart programs. Applications that are written specifically to take advantage of the new ''Restart Manager'' features using the API can be restarted and restored to the same state and with the same data as before the restart. Using the ''Application Recovery and Restart'' APIs in conjunction with the ''Restart Manager'' enables applications to control what actions are taken on their behalf by the system when they fail or crash such as recovering unsaved data or documents, restarting the application, and diagnosing and reporting the problem using [[Windows Error Reporting]].
<!-- Deleted image removed: [[Image:Vista Shutdown.png|thumb|right|A screenshot of Windows Vista's shutdown overlay UI|{{deletable image-caption|1=Tuesday, 22 September 2009}}]] -->
* When shutting down or restarting Windows, previous Windows versions either forcibly terminated applications after waiting for few seconds, or allowed applications to entirely cancel shutdown without informing the user. Windows Vista now informs the user in a full-screen interface if there are running applications when exiting Windows
* ''Clean service shutdown'': Services in Windows Vista have the capability of delaying the system shutdown in order to properly flush data and finish current operations. If the service stops responding, the system terminates it after 3 minutes. Crashes and restart problems are drastically reduced since the Service Control Manager is not terminated by a forced shutdown anymore.
Line 207 ⟶ 209:
* [[Transactional NTFS]] allows multiple file/folder operations to be treated as a single operation, so that a crash or power failure won't result in half-completed file writes. Transactions can also be extended to multiple machines.

* [[Live File System]]: A writable [[Universal Disk Format|UDF]] file system.<ref name="WindowsVistaOpticalPlatform"/> The Windows [[Universal Disk Format|UDF]] file system (UDFS) implementation was read-only in OS releases prior to Windows Vista. In Windows Vista, [[Mount Rainier (packet writing)|Packet writing]] (incremental writing) is supported by UDFS, which can now format and write to all mainstream optical media formats ([[Magneto-optical drive|MO]], CDR/RW, DVD+R/RW, DVD-R/RW/RAM). Write support is included for UDF format versions up to and including 2.50, with read support up to 2.60. UDF symbolic links, however, are not supported.<ref name="FilingCabinet">{{cite web |url=https://blogs.technet.com/filecab/articles/454702.aspx |title=Universal Disk FOrmat (UDF) Beta Chat Transcript (September 01, 2006) |publisher=[[Microsoft]] |work=MSDN Blogs |access-date=December 21, 2015 |archive-date=February 28, 2009 |archive-url=https://web.archive.org/web/20090228015926/http://blogs.technet.com/filecab/articles/454702.aspx |url-status=live }}</ref>

* A new tab, "Previous Versions", in the ''Properties'' dialog for any file or folder, provides read-only snapshots of files on local or network volumes from an earlier point in time. This feature is based on the [[Volume Shadow Copy]] technology.
* A new file-based [[disk image]] format called [[Windows Imaging Format]] (WIM), which can be mounted as a partition, or booted from. An associated tool called [[ImageX]] provides facilities to create and maintain these image files.
Line 239 ⟶ 241:
* Signed drivers are required for usage of PUMA, PAP (Protected Audio Path), and PVP-OPM subsystems.
* Driver packages that are used to install driver software are copied in their entirety into a "Driver Store", which is a repository of driver packages and located in <code>C:\Windows\System32\DriverStore</code>. In essence, DriverStore is similar to [[WinSxS]] but stored for device drivers. This ensures that drivers that need to be repaired or reinstalled won't need to ask for source media to get "fresh" files. The Driver Store can also be preloaded with drivers by an OEM or IT administrator to ensure that commonly used devices (e.g. external peripherals shipped with a computer system, corporate printers) can be installed immediately. Adding, removing and viewing drivers from the "Driver Store" is done using {{mono|PnPUtil.exe}}<ref>{{Cite web |url=http://support.microsoft.com/kb/937793 |title=The staging and the installation of driver packages by using the PnP Utility (Pnputil.exe) in Windows Vista |access-date=2007-10-27 |archive-date=2009-07-22 |archive-url=https://web.archive.org/web/20090722095346/http://support.microsoft.com/kb/937793 |url-status=live }}</ref> A new setting in [[Device Manager]] allows deleting the drivers from the Driver Store when uninstalling the hardware.
* Since Windows Vista, there has a "delete the driver software for this device" clickbox in confirmation dialog when uninstalling a hardware device in Device Manager.
* Support for [[Windows Error Reporting]]; information on an "unknown device" is reported to Microsoft when a driver cannot be found on the system, via Windows Update, or supplied by the user. OEMs can hook into this system to provide information that can be returned to the user, such as a formal statement of non-support of a device for Windows Vista, or a link to a web site with support information, drivers, etc.
===Processor Power Management===
Windows Vista includes the following changes and enhancements in processor [[

The 3D capabilities in WPF are limited compared to what's available in Direct3D. However, WPF provides tighter integration with other features like [[user interface]] (UI), documents, and media. This makes it possible to have 3D UI, 3D documents, and 3D media. A set of built-in controls is provided as part of WPF, containing items such as button, menu, and list box controls. WPF provides the ability to perform control composition, where a control can contain any other control or layout. WPF also has a built-in set of data services to enable application developers to bind data to the controls. Images are supported using the Windows Imaging Component. For media, WPF supports any audio and video formats which Windows Media Player can play. In addition, WPF supports time-based [[animation]]s, in contrast to the frame-based approach. This delinks the speed of the animation from how slow or fast the system is performing. [[wikt:Text|Text]] is anti-aliased and rendered using [[ClearType]].

The criteria for the search is specified using a [[SQL]]-like syntax.
The default catalog is called ''SystemIndex'' and it stores all the properties of indexed items with a predefined naming pattern.

The network projector can be connected to the network via wireless or cable (LAN) technology to make it even more flexible. Users can not only connect to the network projector remotely but can also remotely configure it. Network projectors are designed to transmit and display still images, such as photographs and slides —not high-bandwidth transmissions, such as video streams.
