Windows Vista (formerly codenamed '''Windows "Longhorn"''') has many significant new features compared with previous Microsoft Windows versions, covering most aspects of the operating system. This article discusses the changes most likely to be of interest to non-technical users. The companion article, Technical Features New To Windows Vista , discusses the technical advancements in Windows Vista, while the article Security And Safety Features New To Windows Vista discusses the security advancements. The article Management Features New To Windows Vista discusses the management and administrative improvements, which may be of interest to IT professionals. SHELL & USER INTERFACE Windows Aero See Also: Windows Aero Premium editions of Windows Vista include a redesigned user interface and visual style, named ''Windows Aero (Authentic, Energetic, Reflective and Open)''. Aero is intended to be cleaner and more aesthetically pleasing than previous Windows versions, including transparencies, window animations and Eye Candy . Windows Aero also features a new default font ( Segoe UI ) with a slightly larger size, a streamlined style for Wizards , and a change in the tone and phrasing of most of the dialogs and control panels. In addition to the Windows Aero visual style, Windows Vista includes three other variations: "Standard" which is Windows Aero without the transparencies and glass effects, "Basic" which more closely resembles Windows XP with elements of Aero, and is geared towards lower-end machines that aren't able to use the Desktop Window Manager , and "Classic" which is similar in appearance to Windows 2000. Windows Explorer See Also: Windows Explorer Layout and visualization Windows Explorer's task pane has been removed, integrating the relevant task options into the toolbar. A Favorites pane on the left contains commonly accessed folders and prepopulated ''Search Folders''. Seven different views are available to view files and folders, namely, List, Details, Small icons, Medium icons, Large icons, Extra large icons or Tiles. It is possible to change the layout of the Explorer window by using the Organize button. Users can select whether to display Classic Menus, a Search Pane, a Preview Pane, a Reading Pane, and/or the Navigation Pane. Document Properties are available from the common 'Open' and 'Save' dialog boxes, so it is easier to add metadata (such as ''author'' or ''subject'') to a document. The metadata can be viewed and edited in the ''Properties Pane'' that shows up at the bottom of an Explorer window. The ''Navigation Pane'' contains a list of most common folders (the ''Favorites'') for quick navigation. It can also show the folder layout of the entire hard drive or a subset of it. It can contain both real folders as well as Virtual Ones . By default it contains a links to folders such as ''Documents'' and the publicly shared folder, as well as virtual folders that search and present the saved virtual folders and that lists the recently changed documents. The ''Preview Pane'' can be used to preview the contents of a document, including viewing pictures in a size larger than the thumbnails shown in the folder listing, and sampling contents of a media file, without opening any additional program. Explorer can show a preview for any image format if the necessary codec authored using the '' Windows Imaging Component '' installed. Also, if an application installs proper handlers for the preview pane (like Office 2007 does), then the documents can be edited in the preview pane itself.1 Windows Explorer also contains modifications in the visualization of files on a computer. A new addition to Windows Explorer is the ''Details pane'', which displays metadata and information relating to the currently selected file or folder. The ''Details pane'' will also display a graphical thumbnail of the file (known as ''live icon''). Furthermore, different imagery is overlayed on thumbnails to give more information about the file, such as a picture frame around the thumbnail of an image file, or a filmstrip on a video file. Thumbnails can be zoomed on. The preview panel allows you to see thumbnails of all sorts of files and view the contents of documents, similar to the way you can preview email messages in Outlook, without opening the files. The address bar has been modified to present a Breadcrumbs view, which shows the full path to the current location. Clicking any location in the path hierarchy takes the user to that level, instead of repeatedly pressing the Back button. This is roughly analogous to what is possible today by pressing the small down-arrow next to "Back" and selecting any folder from a list of previously accessed folders. It is also possible to navigate to any subfolder of the current folder using the arrow to the right of the last item, or to click in the space to the right of this to copy or edit the path manually. As with many other Microsoft-made Windows Vista applications, the menu bar is hidden by default. Pressing the Alt key makes the menu bar appear. Free and used space on all drives is shown in horizontal indicator bars. Check boxes allow the selection of multiple files. Icons Icons in Windows Vista are visually more realistic than illustrative. Icons are scalable in size up to 256 x 256 (512 KB), Resolution - Independent and optimized for high- DPI Displays . Required icon sizes are 16 x 16, 32 x 32, and 256 x 256. Optional sizes are 24 x 24, 48 x 48, 64 x 64, 96 x 96, and 128 x 128. Document icons show the actual document contents and several media types are distinguished by icon overlays (video, audio, photos). The icons can be zoomed in and out using a gradual slider or by holding down the ''Ctrl'' key and using the mouse scroll wheel. To optimize and reduce the size of large icons, icons may be stored as compressed PNG s. To maintain backward compatibility with earlier versions of Windows, only larger sized icons can use lossless PNG compression. Organizing & metadata Windows Explorer includes significant changes from previous versions of Windows in terms of organization, navigation, filtering, sorting, grouping and stacking. Combined with integrated desktop searching, Explorer allows users to find and organize their files in new ways, such as "Stacks". The "Stacks" view groups files according to the criterion specified by the user. Stacks can be clicked to filter the files shown in Windows Explorer. Windows Explorer also sorts files on-the-fly automatically as they are renamed or pasted. The ''Details pane'' also allows for the change of some textual metadata such as 'Author' and 'Title' in files that support them within Windows Explorer. A new type of metadata called tags allows users to add descriptive terms to documents for easier categorization and retrieval. Some files support open metadata, allowing users to define new types of metadata for their files. Out-of-the-box, Windows Vista supports Microsoft Office documents and most audio and video files. Metadata support for other file types can however be added by writing Shell Extension s. Unlike previous versions of Windows, all metadata is stored inside the file, so that it will always travel with the file. However, initially, users will be able to add metadata to only a few file types. Windows Vista Help: Add tags or other properties to files File operations In Windows Vista, when moving or copying files, if a conflict or error is encountered, it does not terminate the copy or move operation. Rather the file is skipped and the rest of the files processed. At the end of the operation, the errors are presented to the user with resolution options (if available). If two files have the same name, an option is available to rename the file; in previous versions of Windows, the only options were to either replace the destination file or cancel the process. The user can also choose to apply the same action to the further conflicts, if any. When renaming a file (when extensions are being displayed), Explorer only highlights the filename without selecting the extension. In case a file is in use or "locked" by another application, Windows Explorer informs users to close the application and retry the file operation. Also, a new interface IFileIsInUse is introduced into the API which developers can use to let other applications switch to the main window of the application that has the file open or simply close the file from the "File In Use" dialog. 'File in Use' Demystified If the running application exposes these operations by means of the IFileInUse interface, Windows Explorer, upon encountering a locked file, allows the user to close the file or switch to the application from the dialog box itself.Default Programs A common issue in previous Windows versions was that competing applications doing common tasks each tried to associate themselves as the default for a certain file type using their own custom user interface. The default application information for a particular file type was stored in the registry on a per-machine basis, resulting in applications changing another user's default program when one user's defaults were changed and each application querying several different registry values when launched. In Windows Vista onwards, File Type Associations and protocol handlers can be set on a per-user basis using the new ''Default Programs'' API, meaning default programs for file types and tasks can be different for each individual user. There is an API for calling a common ''user interface'' so applications no longer need to maintain their own file association UI. The Default Programs API gives applications a programmatic way to check for and discover other default applications, restore a single or all registered defaults, query for the owner of a specific default file association/protocol, launch the ''Default Programs UI'' for a specific application or clear all per user associations. Applications only need to registered at install time to be part of ''Default Programs''. Windows Flip and Flip 3D For all Vista Premium Ready PCs, when using Alt+Tab to switch between open windows, a preview of each open window appears instead of just the program icon. In addition, Windows Flip 3D enables users to flip through a cascading stack of their open windows using the mouse scroll wheel. Windows can be stacked and rotated in 3D to provide views of all of them simultaneously. (The keyboard shortcuts are ''Win+Tab'', which makes Flip 3D disappear after releasing, ''Ctrl+Win+Tab'', which keeps Flip 3D visible after releasing, and ''Win+Shift+Tab'' to flip through open windows backward).2 The window buttons on the taskbar show a thumbnail image of the window, when the mouse hovers over the button. Other shell improvements
Search See Also: Windows Search Windows Vista features system-wide integrated search, called ''Instant Search'' (also known as (''Windows Search'').4 ''Instant Search'' is designed to run significantly faster and offers more customized search capabilities. Search boxes have been added throughout the Explorer user interface, to the Start menu, Open/Save dialog boxes, and several of the applications included with Windows Vista. By default, Instant Search indexes only a small number of folders such as the start menu, the names of files opened, the Documents folder, and the user's e-mail. Beyond searching for files, search works with Help, Control Panel, Networking, and more. In Control Panel, for example, typing "firewall" will instantly return all applets that have to do with the system firewall. Five Great Features in Windows Vista RC1 The search engine uses indexing to allow for a quick display of results for a given search. Advanced options allow the user to choose the file type, how it should be indexed, the properties only, or the properties and the file contents. The Start menu search also doubles as the ''Run'' command from previous versions of Windows; simply typing any command will execute it. The indexed search platform is based on Microsoft 's Windows Desktop Search 3.0, allowing third-party applications (e.g. Microsoft Outlook 2007) to use the indexing platform to store metadata and perform searches on Windows Vista or Windows XP (with the Windows Desktop Search redistributable installed). This is in contrast to the search engine of Windows XP, which takes some time to display results, and only after the user has finished typing the search string. The Windows Vista search allows users to add multiple filters to continually refine search results (Such as "File contains the word 'example'"). It is also possible to search across RSS and Atom feeds, straight from Windows Explorer. Windows search uses IFilters that are used by Windows Desktop Search as well. The IFilter interface can be implemented by software makers so that files created by their applications can be better integrated with search and indexing programs. Searching can also be done from the box at the bottom of the start menu, so it possible to start a program from here by typing its name, for example "Calc" to start the calculator, "Word" to start Microsoft Word, "Mail" to open Windows Mail, a web address to start the default browser at a particular site, the default search engine, or even a folder name, filename or network share name. There is also the ability to save searches as a Search Folder where opening the folder will execute a specific search automatically and display the results as a normal folder. A search folder is just an XML file which stores the search query, including the search operators as well. When these files are accessed, the search is run with the saved query string and the results presented as a virtual folder. Windows Vista also supports query composition, where a saved search (called a ''scope'') can be nested within the query string of another search.5 These virtual folders are also distributable via RSS . Windows Vista also features an enhanced file content search for non-indexed locations, whereby the files being scanned are processed by the same IFilters that would be used for indexing, therefore offering more consistent results between indexed and non-indexed searches as well as the ability for third-parties to add support for additional file formats to have their content searched. Windows Sidebar See Also: Windows Sidebar Windows Sidebar is a new panel which can be placed on either the left or the right-hand side of the screen where a user can place Desktop Gadgets , which are small applets designed for a specialized purpose (such as displaying the weather or sports scores). The gadgets can also be placed on other parts of the desktop, if desired, by dragging. By default, Windows Vista ships with thirteen gadgets: Calculator, Clock, CPU Meter, Currency Conversion, Feed Viewer, Feed Watcher, Notes, Number Puzzle, Picture Puzzle, Recycle Bin, Slide Show, Stocks, and an egg timer. Additional gadgets are published at Microsoft's web site, which offers both Microsoft-created and user-submitted gadgets in a gallery. Gadgets are written using a combination of DHTML for visual layout, JScript and VBScript for functional code, and an XML file for defining the gadget's metadata (author name, description, etc.) The gadget is then distributed as a ZIP file with a .gadget extension. Displaying the gadget using DHTML allows the same gadget to be used on Microsoft's Live.com and Windows Live Spaces sites. Alternatively, on Windows Vista, the gadget can detect that WPF is available and take advantage of its graphical abilities to display in a different way from the web.

Windows Internet Explorer 7 7]] See Also: Internet Explorer Internet Explorer 7 Windows Vista includes the latest version of Internet Explorer, which adds support for Tabbed Browsing , Atom , RSS , Internationalized Domain Name s, a search box, a Phishing filter, an anti-spoofing URL engine, fine-grained control over ActiveX add-ons, thumbnails of all open tabs in a single window (called Quick Tabs), page zoom, and tab groups. Tab groups make it possible to open a folder of Favorites in tabs with a single click. Importing bookmarks and cookies from other web browsers is also supported. Additionally, there is now proper support for PNG images with transparency as well as improvements and fixes to CSS and HTML rendering. The Windows RSS Platform offers native RSS support, with developer APIs. The Windows Vista and XP version of Windows Internet Explorer 7 additionally feature an update to the WinInet API. The new version has better support for IPv6 , and handles hexadecimal literals in the IPv6 address. It also includes better support for Gzip and Deflate compression, so that communication with a web server can be compressed and thus will require less data to be transferred. IE's Gzip and deflate support IE already supports Gzip and deflate Internet Explorer Protected Mode support in WinInet is exclusive to Windows Vista. Windows Media Player 11 11]] See Also: Windows Media Player Windows Media Player 11, which is also available on playback also requires third-party components to be installed. The ''Media Library'' is now presented without the category trees which were prominent in the earlier versions. Rather, on selecting the category in the left pane, the contents appear on the right, in a graphical manner with thumbnails — a stark departure from textual presentation of information. Search has been upgraded to be much faster. Other features of Windows Media Player 11 include:
Windows Media Center ]] See Also: Windows Media Center Media Center in Windows Vista, available in the Home Premium and Ultimate editions, has been upgraded significantly, including a considerable overhaul of the user interface. Each button in the main menu, which contains sections such as "Music", "Videos", and "TV", gets encased in a box when selected, and for each selection, a submenu comes up, extending horizontally. When any of the options is selected, the entries for each are presented in a grid-like structure, with each item being identified by album art, if its an audio file, or a thumbnail image if it is a picture, a video or a TV recording, and other related options, such as different views for the music collection if "Music" is selected, extend horizontally along the top of the grid. Similarly, other items are identified by suggestive artwork. The grid displaying the items is also extended horizontally, and the selected item is enlarged compared to the rest. Other features of Windows Media Center include:
Internet Information Services 7 7's redesigned management console]] See Also: Internet Information Services Windows Vista includes Internet Information Services (IIS) version 7, which has been refactored into a modular architecture, with integrated .NET extensibility. Instead of a monolithic server which features all services, IIS 7 has a core web server engine, and modules offering specific functionality can be added to the engine to enable its features. Writing extensions to IIS 7 using ISAPI has been deprecated in favor of the module API. Much of IIS's own functionality is built on this API, and as such, developers will have much more control over a request process than was possible in prior versions. A significant change from previous versions of IIS is that all web server configuration information is stored solely in XML configuration files, instead of in the metabase. The server has a global configuration file that provides defaults, and each virtual web's document root (and any subdirectory thereof) may contain a web.config containing settings that augment or override the defaults. Changes to these files take effect immediately. This marks a significant departure from previous versions whereby web interfaces, or machine administrator access, was required to change simple settings such as default document, active modules, and security/authentication. IIS 7 also features a completely rewritten administration interface that takes advantage of modern MMC features such as task panes and asynchronous operation. Configuration of ASP.NET is more fully integrated into the administrative interface. Previous versions of IIS included with Windows XP had hard limits on concurrent connections and defined web servers; IIS 7.0 on Vista will not limit the number of connections allowed but will limit workloads based on the active concurrent requests to 10, improving usability and performance in peer-to-peer scenarios. SECURITY AND SAFETY See Also: Security and safety features new to Windows Vista with the underlying ethos of, "Secure by design, secure by default, secure in deployment". New code for Windows Vista was developed with the SDL methodology, and all existing code was reviewed and refactored to improve security. Some of the most significant and most discussed security features included with Windows Vista include User Account Control , Kernel Patch Protection , BitLocker Drive Encryption , and Address Space Layout Randomization . Additionally, Windows Vista includes a range of Parental Controls , which give owners of a computer a set of tools to limit what other accounts on a computer can do, and an improved Windows Firewall which supports both inbound and outbound packet filtering, IPv6 connection filtering and more detailed configurable rules and policies. Vista also incorporates a range of Digital Rights Management features allowing 'premium content' while respecting the rights of the movie industry, at the cost of a slight percentage of system resources. MANAGEMENT AND ADMINISTRATION See Also: Management features new to Windows Vista Windows Vista contains a range of new technologies and features that are intended to help Network Administrator s and Power User s better manage their systems. Notable changes include a complete replacement of the "Windows Setup" process based on Windows Preinstallation Environment (WinPE), completely rewritten Image-based deployment mechanisms, GUI Recovery Tools , support for per-application Remote Desktop sessions, new diagnostic, health monitoring and system administration tools, and a range of new Group Policy settings covering many of the new features. GRAPHICS Desktop Window Manager The Desktop Window Manager (DWM) is the new Windowing System available in premium (but not Starter and Home Basic) versions of Windows Vista. It enables the new Windows Aero user interface. The DWM handles the drawing of all content to the screen. Instead of windows drawing directly to the video card's memory buffers, contents are instead rendered to back-buffers (technically Direct3D surfaces), which are then arranged in the appropriate Z-order, then displayed to the user. This drawing method uses significantly more video memory than the traditional window-drawing method used in previous versions of Windows, which only required enough memory to contain the composite of all currently visible windows at any given time. With the entire contents of windows being stored in video memory, a user can move windows around the screen smoothly, without having "tearing" artifacts be visible while the operating system asks applications to redraw the newly visible parts of their windows. Other features new to Windows Vista such as live thumbnail window previews and Flip 3D are implemented through the DWM. Users will need to have a DirectX 9 capable video card to be able to use the Desktop Window Manager. Machines that can't use the DWM will fall back to a "Basic" theme, and use screen drawing methods similar to Windows XP. DirectX See Also: Direct3D Windows Vista includes a new version of Direct3D, called Direct3D 10. It adds scheduling and memory virtualization capabilities to the graphics subsystem and foregoes the current DirectX practice of using "capability bits" to indicate which features are active on the current hardware. Instead, Direct3D 10 defines a minimum standard of hardware capabilities which must be supported for a display system to be "Direct3D 10 compatible". Microsoft's goal is to create an environment for developers and designers where they can be assured that the input they provide will be rendered in exactly the same fashion on all supported graphics cards. This has been a recurring problem with the DirectX 9 model, where different video cards have produced different results, thus requiring fixes keyed to specific cards to be produced by developers. According to Microsoft, Direct3D 10 will be able to display some graphics up to 8 times faster than DirectX 9.0c because of the new improved Windows Display Driver Model . In addition, Direct3D 10 incorporates Microsoft's High Level Shader Language 4.0. However, Direct3D 10 is not backward compatible like prior versions of DirectX. The same game will not be compatible with both Direct3D 10 ''and'' Direct3D 9 or below. Games would need to be developed for both APIs, one version for Direct3D 9 and below if targeting Windows versions prior to Windows Vista and another version using Direct3D 10 if targeting only Windows Vista. Windows Vista does, however, contain a backward compatible Direct3D 9 implementation. The Direct3D 10 API introduces unified Vertex and Pixel Shaders . In addition, it also supports ''Geometry Shaders'', which operate on entire geometric primitives (points, lines, and triangles), and can allow calculations based on adjacent primitives as well. The output of the geometry shader can be passed directly onwards to the rasterizer for interpolation and pixel shading, or written to a vertex buffer (known as 'stream out') to be fed back into the beginning of the pipeline. D3D10 functionality requires WDDM ( Windows Display Driver Model ) and new graphics hardware. The graphics hardware will be pre-emptively multithreaded, to allow multiple threads to use the GPU in turns. It will also provide paging of the graphics memory. The version of Direct3D 9 available in Windows Vista is called Direct3D 9Ex. This modified API also uses the WDDM and allows Direct3D 9 applications to access some of the features available in Windows Vista such as cross-process shared surfaces, managed graphics memory, prioritization of resources, text anti-aliasing, advanced gamma functions, and device removal management. Deprecation of other DirectX APIs: In Windows Vista, only Direct3D features an overhaul. The DirectX SDK mentions that most of the other APIs have been deprecated. DirectInput and DirectPlay have been deprecated. DirectSound lacks hardware abstraction and is emulated in software. Only DirectMusic has been included intact. Imaging See Also: Windows Imaging Component HD Photo Windows Imaging Component (WIC) is a new extensible imaging framework that allows applications supporting the framework to automatically get support of installed codecs for Graphics File Format s. Windows Presentation Foundation applications also automatically support the installed image codecs. Third party developers can write their own image codecs for their specific image file formats. By default, Windows Vista ships with the JPEG , TIFF , GIF , PNG , BMP and HD Photo codecs. Codecs for RAW image formats used generally by high-end digital cameras are also supported in this manner. Windows Explorer , Windows Photo Gallery and Windows Photo Gallery Viewer are based on this new framework and can thus view and export images in any format for which the necessary codecs are installed. , that is introduced with Windows Vista. It supports features such as High Dynamic Range Imaging , Lossy as well as Lossless Compression , up to 32- Bpp Fixed or Floating Point representation, Transparency , RGB , CMYK and n-channel Color Space s, Radiance RGBE, embedded ICC color profiles, multiple images per file and support for Exif and XMP Metadata formats. It is the preferred image format for XPS documents. Color management See Also: Windows Color System Windows Vista features ''Windows Color System (WCS)'', Windows Color System a platform for Color Management . Its goal is to obtain color consistency across various software and hardware, including cameras, monitors, printers and scanners. Different devices interpret the same colors differently, according to their software and hardware configurations. As a result, they must be properly calibrated to reproduce colors consistently across different devices. WCS aims to make this process of color calibration automatic and transparent, as an evolution of ICC Color Profiles. Windows Color System is based on a completely new ''Color Infrastructure and Translation Engine'' (CITE). It is backed up by a new color processing pipeline that supports bit-depths more than 32 bits per pixel, multiple color channels (more than 3), alternative color spaces and high dynamic range coloring, using a technology named ''Kyuanos'' Windows Vista to use Canon software developed by Canon . The color processing pipeline allows device developers to add their own Gamut mapping algorithm into the pipeline to customize the color response of the device. The new pipeline also uses floating point calculations to minimize round-off losses, which are inherent in integer processing. Once the color pipeline finishes processing the colors, the CITE engine applies a ''color transform'' according to a color profile, specific to a device to ensure the output color matches to what is expected. WCS features explicit support for LCD as well as CRT monitors, projectors, printers, and other imaging devices and provides customized support for each. WCS uses color profiles according to the CIE Color Appearance Model recommendation (CIECAM02), defined using XML , to define how the color representation actually translates to a visible color. ICC V4 color profiles are also supported. Windows Photo Gallery and Photo Viewer, Windows Imaging Component , the HD Photo format, XPS print path and XPS documents all support color management. MOBILE COMPUTING Some significant changes have been made to Windows Vista for mobile computing. Power management In Windows Vista, 'Stand By' and 'Hibernate' have been combined into an additional 'Sleep' function which is active by default. When chosen, this new "Sleep" mode saves information from the computer's memory to the hibernation file on disk, but instead of turning off the computer, it simultaneously enters Standby mode. After a specified amount of time (3 hours by default), it shuts down (hibernates). If power is lost during Standby mode, the system resumes from the existing hibernate image on disk. Sleep mode, thus, offers the benefits of fast suspend and resume when in Standby mode and reliability when resuming from hibernation, in case of power loss. Also, in earlier Windows versions, drivers sometimes prevented Windows from entering or reliably resuming from a power-saving state. This problem has been solved in Windows Vista. Applications can disable sleep idle timers when needed such as when burning discs or recording media. Away mode, which is not a power plan by itself but a feature, automatically turns off displays, video rendering and sound but keeps the computer working when the user is away from the computer. Optionally, it can also switch to sleep mode. Power settings are also configurable through Group Policy. Other mobility enhancements
