With the new asynchronous I/O APIs, a thread, different from the one that issued the I/O request, can be notified when the operation completes.

With this, a single thread can issue all the I/O requests, and then switch to a different worker thread. If this thread is the one that handles the data after the I/O request completes, then a thread- switch, which causes a performance hit, may be avoided. Windows Vista also introduces synchronous I/O cancellation.

During a synchronous I/O request, the application is blocked until the request is serviced or fails. In Windows Vista the application may issue a cancellation request. Applications that cancel the operation on user feedback may prefer to enable user feedback during the time the issuing thread is suspended for usability.

Windows Vista introduced a number of new I/O functions to the Microsoft Windows line of operating systems. They are intended to shorten the time taken to boot the. Microsoft Windows 7 offers solid functionality for reinstalling sound playback devices. Microsoft compiled a plethora of drivers for sound playback devices in order.

I have an older HP Pavilion DV6810us that originally came with Vista. After 8.1 Pro install I have no sound device or recording device detected & no sound.

Windows Vista also implements I/O scheduling as prioritized I/O. Windows Vista defines five priority classes – Very Low, Low, Normal, High and Critical. By default I/O requests are assigned Normal priority.

Windows Vista also allows reservation of bandwidth on a per- application basis during disk access; this aims to guarantee the required throughput rate to the application when it accesses the disk. Both these features are used by Windows Media Player with respect to media playback. In Windows Vista, there is no limit on the size of I/O requests.

This means an entire I/O operation can be completed by issuing fewer requests, which in turn may lead to higher performance. Windows Explorer and the Command Prompt'scopy command have been modified to issue 1 MB requests.

When such a device is plugged in, the Windows Autoplay dialog offers an additional option to use it to speed up the system; an additional . Windows Readyboosy is also available for windows 7 and Windows 1. It should be noted that most flash memory devices are formatted in the FAT3. This will need to be changed of one wants to properly utilize a larger flash device for Readyboost. But if one activates Readyboost using Windows Autoplay reformatting the device will become impossible until Readyboost for that device is disabled.

The drive- side functionality is expected to be standardized in ATA- 8. When a hybrid hard drive is installed in a Windows Vista machine, the operating system will display a new . It is based on the . It does so by continually analyzing application behavior and usage patterns, e. Although hard disks usually have higher sequential data transfer rates, flash drives can be faster for small files or non- sequential I/O because of their short random seek times. Offline Files. It locally caches shared files marked for offline access, and uses the cached copy whenever the network connection to the remote files is interrupted. Windows Vista Business, Enterprise and Ultimate editions contain significant improvements to Offline Files.

If in your Windows 10 / 8 / 7, Windows Vista or Windows XP computer, you find that there is no sound or that sound is missing, then this Fix It from Microsoft.

Beginning with Windows Vista, whenever the connection is restored, all open file handles to the cached copy are redirected to the remote version, without waiting for the cached files to be synchronized. The local copy is automatically synchronized with the remote copy, to reflect the changes made on either copy of the file. The file caching and sync algorithm has also been completely rewritten to determine the differences faster.

When synchronizing the changes in the cached copy to the remote version, the Bitmap Differential Transfer protocol is used so that only the changed blocks in the cached version are transferred. This also improves support for caching large files. Sync Center can also report sync errors and resolve sync conflicts. The property page for any file or folder has an Offline Files tab that provides status and allows control of the offline status of the file or folder. Moreover, even if a single file is unavailable, other files in the same share and other shares are available as the transition is now at the share level instead of server level. Offline Files are configurable through Group Policy and provide better interoperability with DFS. Also, a comprehensive Offline Files management API is available via COM objects and scriptability through WMI.

Windows Vista also supports . When users make only a few files from a directory available offline, Windows Vista creates ghosted entries of the remaining unavailable items to preserve the online context. Offline Files also feature slow- link mode which when enabled through Group Policy, always reads from and writes to the local cache to improve performance over a slow network connection. It is also possible in Windows Vista to specify a limit for the total size of the local cache and another sub- limit for the space used by automatically cached files. Manually cached files are never removed from the local cache even if the cache limit is reached. In Windows XP, Offline Files could not be enabled when Fast User Switching was enabled. This restriction applied because .

In Windows Vista, this restriction no longer applies as Offline Files runs as a Windows service that performs synchronization for the user at opportune times such as logon and offline to online transitions. Synchronization does not occur continuously in the background. Transactional NTFS allows for files and directories to be created, renamed, and deleted atomically. Using a transaction ensures correctness of operation; in a series of file operations (done as a transaction), the operation will be committed if all the operations succeed. In case of any failure, the entire operation will roll back and fail.

Shadow Copy. The Backup and Restore Center in Windows Vista and later performs block- based backups when doing full system backups. The file backup feature also uses shadow copy but stores files inside ZIP files. Beginning with Windows Vista, Shadow Copy is also used by the System Protection component which creates and maintains periodic copies of system and user data on the same local volume (similar to the Shadow Copies for Shared Folders feature in Windows Server) but allows it to be locally accessed by System Restore. System Restore allows reverting to an entire previous set of shadow copies called a Restore point.

Prior to Windows Vista, System Restore was based on a file- based filter that watched changes for a certain set of file extensions, and then copied files before they were overwritten. Retrieved July 1.

Windows Vista - Wikipedia. Windows Vista (codenamed Longhorn. Development was completed on 8 November 2.

On 3. 0 January 2. It was succeeded by Windows 7, which was released to manufacturing on 2. July 2. 00. 9 and released worldwide for retail on 2. October 2. 00. 9.

New features of Windows Vista include an updated graphical user interface and visual style dubbed Aero, a new search component called Windows Search, redesigned networking, audio, print and display sub- systems, and new multimedia tools such as Windows DVD Maker. Vista aimed to increase the level of communication between machines on a home network, using peer- to- peer technology to simplify sharing files and media between computers and devices. Windows Vista included version 3. NET Framework, allowing software developers to write applications without traditional Windows APIs.

Microsoft's primary stated objective with Windows Vista was to improve the state of security in the Windows operating system. In light of this, Microsoft chairman Bill Gates announced in early 2. Criticism of Windows Vista has targeted its high system requirements, its more restrictive licensing terms, the inclusion of a number of, then, new DRM technologies aimed at restricting the copying of protected digital media, lack of compatibility with some pre- Vista hardware and software, longer boot time, and the number of authorization prompts for User Account Control. As a result of these and other issues, Windows Vista had seen initial adoption and satisfaction rates lower than Windows XP.

It was originally expected to ship sometime late in 2. Windows XP and Blackcomb, which was planned to be the company's next major operating system release. Gradually, . In some builds of Longhorn, their license agreement said . Many of Microsoft's developers were also re- tasked to build updates to Windows XP and Windows Server 2. Faced with ongoing delays and concerns about feature creep, Microsoft announced on 2.

August 2. 00. 4, that it had revised its plans. For this reason, Longhorn was reset to start work on componentizing the Windows Server 2. Service Pack 1 codebase, and over time re- incorporating the features that would be intended for an actual operating system release. However, some previously announced features such as Win. FS were dropped or postponed, and a new software development methodology called the Security Development Lifecycle was incorporated in an effort to address concerns with the security of the Windows codebase, which is programmed in C, C++ and assembly.

Longhorn became known as Vista in 2. During this period, Microsoft was fairly quiet about what was being worked on, as their marketing and public relations focus was more strongly focused on Windows XP, and Windows Server 2.

April 2. 00. 3. Occasional builds of Longhorn were leaked onto popular file sharing networks such as IRC, Bit. Torrent, e. Donkey and various newsgroups, and so most of what is known about builds prior to the first sanctioned development release of Longhorn in May 2. After several months of relatively little news or activity from Microsoft with Longhorn, Microsoft released Build 4. Internet around 2. February 2. 00. 3.

As an evolutionary release over build 3. An optional . The incorporation of the Plex theme made blue the dominant color of the entire application. The Windows XP- style task pane was almost completely replaced with a large horizontal pane that appeared under the toolbars. A new search interface allowed for filtering of results, searching of Windows help, and natural- language queries that would be used to integrate with Win.

FS. The animated search characters were also removed. File metadata was also made more visible and more easily editable, with more active encouragement to fill out missing pieces of information. Also of note was the conversion of Windows Explorer to being a . NET application. Most builds of Longhorn and Vista were identified by a label that was always displayed in the bottom- right corner of the desktop. A typical build label would look like . Higher build numbers did not automatically mean that the latest features from every development team at Microsoft was included.

Typically, a team working on a certain feature or subsystem would generate their own working builds which developers would test with, and when the code was deemed stable, all the changes would be incorporated back into the main development tree at once. At Microsoft, a number of . The name of the lab in which any given build originated is shown as part of the build label, and the date and time of the build follows that. Some builds (such as Beta 1 and Beta 2) only display the build label in the version information dialog (Winver). The icons used in these builds are from Windows XP. At the Windows Hardware Engineering Conference (Win.

HEC) in May 2. 00. Microsoft gave their first public demonstrations of the new Desktop Window Manager and Aero. The demonstrations were done on a revised build 4. A number of sessions for developers and hardware engineers at the conference focused on these new features, as well as the Next- Generation Secure Computing Base (previously known as .

Also at this conference, Microsoft reiterated their roadmap for delivering Longhorn, pointing to an . Internally, some Microsoft employees were describing the Longhorn project as . It offered only a limited subset of features planned for Longhorn, in particular fast file searching and integrated graphics and sound processing, but appeared to have impressive reliability and performance compared to contemporary Longhorn builds.

Allchin went on to explain how in December 2. Brian Valentine and Amitabh Srivastava, the former being experienced with shipping software at Microsoft, most notably Windows Server 2. Future Longhorn builds would start from Windows Server 2. Service Pack 1 and continue from there. This change, announced internally to Microsoft employees on 2.

August 2. 00. 4, began in earnest in September, though it would take several more months before the new development process and build methodology would be used by all of the development teams. A number of complaints came from individual developers, and Bill Gates himself, that the new development process was going to be prohibitively difficult to work within. As Windows Vista. By approximately November 2.

In the end, Microsoft chose Windows Vista as confirmed on 2. July 2. 00. 5, believing it to be a . That's what Windows Vista is all about: . In September of that year, Microsoft started releasing regular Community Technology Previews (CTP) to beta testers from July 2.

February 2. 00. 6. The first of these was distributed at the 2. Microsoft Professional Developers Conference, and was subsequently released to beta testers and Microsoft Developer Network subscribers. The builds that followed incorporated most of the planned features for the final product, as well as a number of changes to the user interface, based largely on feedback from beta testers. Windows Vista was deemed feature- complete with the release of the . Beta 2, released in late May, was the first build to be made available to the general public through Microsoft's Customer Preview Program. It was downloaded by over five million people.

Two release candidates followed in September and October, both of which were made available to a large number of users. The UEFI 2. 0 specification (which replaces EFI 1.

Microsoft's announcement, no firmware manufacturers had completed a production implementation which could be used for testing. As a result, the decision was made to postpone the introduction of UEFI support to Windows; support for UEFI on 6.

Vista Service Pack 1 and Windows Server 2. UEFI would not be supported, as Microsoft does not expect many such systems to be built as the market moves to 6. Because a release to manufacturing (RTM) build is the final version of code shipped to retailers and other distributors, the purpose of a pre- RTM build is to eliminate any last . Thus, it is unlikely that any major new features would be introduced; instead, work would focus on Vista's . In just a few days, developers had managed to drop Vista's bug count from over 2. September to just over 1. RC2 shipped in early October.

However, they still had a way to go before Vista was ready to RTM. Microsoft's internal processes required Vista's bug count to drop to 5.

RTM. During a demonstration of the speech recognition feature new to Windows Vista at Microsoft's Financial Analyst Meeting on 2. July 2. 00. 6, the software recognized the phrase . After several failed attempts to correct the error, the sentence eventually became . On 1. 6 November 2. Microsoft made the final build available to MSDN and Technet Plus subscribers. Laptop users report, however, that enabling Aero shortens battery life.

A search box appears in every Explorer window. The address bar has been replaced with a breadcrumb navigation bar. Icons of certain file types in Windows Explorer are . The preview pane allows users to see thumbnails of various files and view the contents of documents. The details pane shows information such as file size and type, and allows viewing and editing of embedded tags in supported file formats. The Start menu has changed as well; incorporating an instant search box, and the All Programs list uses a horizontal scroll bar instead of the cascading flyout menu seen in Windows XP. Gadgets can also be placed on the desktop.

IE7 in Windows Vista runs in isolation from other applications in the operating system (protected mode); exploits and malicious software are restricted from writing to any location beyond Temporary Internet Files without explicit user consent.
