The Microsoft Windows Script Host (WSH) (formerly named Windows Scripting Host) is an automation technology for Microsoft Windows operating systems that provides scripting abilities comparable to batch files, but with a wider range of supported features. This tool was first provided on Windows 95 after Build 950a on the installation discs as an optional installation configurable and installable by means of the Control Panel, and then a standard component of Windows 98 (Build 1111) and subsequent and Windows NT 4.0 Build 1381 and by means of Service Pack 4. The WSH is also a means of automation for Internet Explorer via the installed WSH engines from IE Version 3.0 onwards; at this time VBScript became means of automation for Microsoft Outlook 97.^[1] The WSH is also an optional install provided with a VBScript and JScript engine for Windows CE 3.0 and following and some third-party engines including Rexx and other forms of Basic are also available.^[2][3][4]

It is language-independent in that it can make use of different Active Scripting language engines. By default, it interprets and runs plain-text JScript (.JS and .JSE files) and VBScript (.VBS and .VBE files).

Users can install different scripting engines to enable them to script in other languages, for instance PerlScript. The language independent filename extension WSF can also be used. The advantage of the Windows Script File (.WSF) is that it allows multiple scripts («jobs») as well as a combination of scripting languages within a single file.

WSH engines include various implementations for the Rexx, BASIC, Perl, Ruby, Tcl, PHP, JavaScript, Delphi, Python, XSLT, and other languages.

Windows Script Host is distributed and installed by default on Windows 98 and later versions of Windows. It is also installed if Internet Explorer 5 (or a later version) is installed. Beginning with Windows 2000, the Windows Script Host became available for use with user login scripts.

Usage[edit]

Windows Script Host may be used for a variety of purposes, including logon scripts, administration and general automation. Microsoft describes it as an administration tool.^[5] WSH provides an environment for scripts to run – it invokes the appropriate script engine and provides a set of services and objects for the script to work with.^[5] These scripts may be run in GUI mode (WScript.exe) or command line mode (CScript.exe), or from a COM object (wshom.ocx), offering flexibility to the user for interactive or non-interactive scripts.^[6] Windows Management Instrumentation is also scriptable by this means.

The WSH, the engines, and related functionality are also listed as objects which can be accessed and scripted and queried by means of the VBA and Visual Studio object explorers and those for similar tools like the various script debuggers, e.g. Microsoft Script Debugger, and editors.

WSH implements an object model which exposes a set of Component Object Model (COM) interfaces.^[7] So in addition to ASP, IIS, Internet Explorer, CScript and WScript, the WSH can be used to automate and communicate with any Windows application with COM and other exposed objects, such as using PerlScript to query Microsoft Access by various means including various ODBC engines and SQL, ooRexxScript to create what are in effect Rexx macros in Microsoft Excel, Quattro Pro, Microsoft Word, Lotus Notes and any of the like, the XLNT script to get environment variables and print them in a new TextPad document, and so on.

The VBA functionality of Microsoft Office, Open Office (as well as Python and other installable macro languages) and Corel WordPerfect Office is separate from WSH engines although Outlook 97 uses VBScript rather than VBA as its macro language.^[8]

Python in the form of ActiveState PythonScript can be used to automate and query the data in SecureCRT, as with other languages with installed engines, e.g. PerlScript, ooRexxScript, PHPScript, RubyScript, LuaScript, XLNT and so on. One notable exception is Paint Shop Pro, which can be automated in Python by means of a macro interpreter within the PSP programme itself rather than using the PythonScript WSH engine or an external Python implementation such as Python interpreters supplied with Unix emulation and integration software suites or other standalone Python implementations et al.^[9][10] as an intermediate and indeed can be programmed like this even in the absence of any third-party Python installation; the same goes for the Rexx-programmable terminal emulator Passport.^[11] The SecureCRT terminal emulator, SecureFX FTP client, and related client and server programmes from Van Dyke are as of the current versions automated by means of the WSH so any language with an installed engine may be used; the software comes with VBScript, JScript, and PerlScript examples.

As of the most recent releases and going back a number of versions now, the programmability of 4NT / Take Command in the latest implementations (by means of «@REXX» and similar for Perl, Python, Tcl, Ruby, Lua, VBScript, JScript and the like and so on) generally uses the WSH engine.^[12] The ZOC terminal emulator gets its ability to be programmed in Rexx by means of an external interpreter, one of which is supplied with the programme, and alternate Rexx interpreters can be specified in the configuration of the programme.^[13][14] The MKS Toolkit provides PScript, a WSH engine in addition to the standard Perl interpreter perl.exe which comes with the package.

VBScript, JScript, and some third-party engines have the ability to create and execute scripts in an encoded format which prevents editing with a text editor; the file extensions for these encoded scripts is .vbe and .jse and others of that type.

Unless otherwise specified, any WSH scripting engine can be used with the various Windows server software packages to provide CGI scripting. The current versions of the default WSH engines and all or most of the third party engines have socket abilities as well; as a CGI script or otherwise, PerlScript is the choice of many programmers for this purpose and the VBScript and various Rexx-based engines are also rated as sufficiently powerful in connectivity and text-processing abilities to also be useful. This also goes for file access and processing—the earliest WSH engines for VBScript and JScript do not since the base language did not,^[15] whilst PerlScript, ooRexxScript, and the others have this from the beginning.

WinWrap Basic, SaxBasic and others are similar to Visual Basic for Applications, These tools are used to add scripting and macro abilities to software being developed and can be found in earlier versions of Host Explorer for example. Many other languages can also be used in this fashion. Other languages used for scripting of programmes include Rexx, Tcl, Perl, Python, Ruby, and others which come with methods to control objects in the operating system and the spreadsheet and database programmes.^[16] One exception is that the Zoc terminal emulator is controlled by a Rexx interpreter supplied with the package or another interpreter specified by the user; this is also the case with the Passport emulator.

VBScript is the macro language in Microsoft Outlook 97, whilst WordBasic is used for Word up to 6, Powerpoint and other tools. Excel to 5.0 uses Visual Basic 5.0. In Office 2000 forward, true Visual Basic for Applications 6.0 is used for all components. Other components use Visual Basic for Applications. OpenOffice uses Visual Basic, Python, and several others as macro languages and others can be added. LotusScript is very closely related to VBA and used for Lotus Notes and Lotus SmartSuite, which includes Lotus Word Pro (the current descendant of Ami Pro), Lotus Approach, Lotus FastSite, Lotus 1-2-3, &c, and pure VBA, licensed from Microsoft, is used in Corel products such as WordPerfect, Paradox, Quattro Pro &c.

Any scripting language installed under Windows can be accessed by external means of PerlScript, PythonScript, VBScript and the other engines available can be used to access databases (Lotus Notes, Microsoft Access, Oracle Database, Paradox) and spreadsheets (Microsoft Excel, Lotus 1-2-3, Quattro Pro) and other tools like word processors, terminal emulators, command shells and so on. This can be accomplished by means of the WSH, so any language can be used if there is an installed engine.

In recent versions of the Take Command enhanced command prompt and tools, the «script» command typed at the shell prompt will produce a list of the currently installed engines, one to a line and therefore CR-LF delimited.^[17][18][19]

Examples[edit]

The first example is very simple; it shows some VBScript which uses the root WSH COM object «WScript» to display a message with an ‘OK’ button. Upon launching this script the CScript or WScript engine would be called and the runtime environment provided.

Content of a file hello0.vbs

WScript.Echo "Hello world"
WScript.Quit

WSH programming can also use the JScript language.

Content of a file hello1.js

WSH.Echo("Hello world");
WSH.Quit();

Or, code can be mixed in one WSF file, such as VBScript and JScript, or any other:

Content of a file hello2.wsf

<job>
<script language="VBScript">
  MsgBox "hello world (from vb)"
</script>
<script language="JScript">
  WSH.echo("hello world (from js)");
</script>
</job>

Security concerns[edit]

Windows applications and processes may be automated using a script in Windows Script Host. Viruses and malware could be written to exploit this ability. Thus, some suggest disabling it for security reasons.^[20] Alternatively, antivirus programs may offer features to control .vbs and other scripts which run in the WSH environment.

Since version 5.6 of WSH, scripts can be digitally signed programmatically using the Scripting.Signer object in a script itself, provided a valid certificate is present on the system. Alternatively, the signcode tool from the Platform SDK, which has been extended to support WSH filetypes, may be used at the command line.^[21]

By using Software Restriction Policies introduced with Windows XP, a system may be configured to execute only those scripts which are stored in trusted locations, have a known MD5 hash, or have been digitally signed by a trusted publisher, thus preventing the execution of untrusted scripts.^[22]

Available scripting engines[edit]

Note: By definition, all of these scripting engines can be utilised in CGI programming under Windows with any number of programmes and set up, meaning that the source code files for a script used on a server for CGI purposes could bear other file extensions such as .cgi and so on. The aforementioned ability of the Windows Script Host to run a script with multiple languages in it in files with a .wsh extension. Extended Html and XML also add to the additional possibilities when working with scripts for network use, as do Active Server Pages and so forth. Moreover, Windows shell scripts and scripts written in shells with enhanced capabilities like TCC, 4NT, etc. and Unix shells under interoperability software like the MKS Toolkit can have scripts embedded in them as well.

There have been suggestions of creating engines for other languages, such as LotusScript, SaxBasic, BasicScript, KiXtart, awk, bash, csh and other Unix shells, 4NT, cmd.exe (the Windows NT shell), Windows PowerShell, DCL, C, C++, Fortran and others.^[24]
The XLNT language^[25] is based on DCL and provides a very large subset of the language along with additional commands and statements and the software can be used in three ways: the WSH engine (*.xcs), the console interpreter (*.xlnt) and as a server and client side CGI engine (*.xgi).^[26]

When a server implementing CGI such as the Windows Internet Information Server, ports of Apache and others, all or most of the engines can be used; the most commonly used are VBScript, JScript, PythonScript, PerlScript, ActivePHPScript, and ooRexxScript. The MKS Toolkit PScript program also runs Perl. Command shells like cmd.exe, 4NT, ksh, and scripting languages with string processing and preferably socket functionality are also able to be used for CGI scripting; compiled languages like C++, Visual Basic, and Java can also be used like this. All Perl interpreters, ooRexx, PHP, and more recent versions of VBScript and JScript can use sockets for TCP/IP and usually UDP and other protocols for this.

Version history[edit]

The redistributable version of WSH version 5.6 can be installed on Windows 95/98/Me and Windows NT 4.0/2000. WSH 5.7 is downloadable for Windows 2000, Windows XP and Windows Server 2003. Recently^[when?], redistributable versions for older operating systems (Windows 9x and Windows NT 4.0) are no longer available from the Microsoft Download Center.

Since Windows XP Service Pack 3, release 5.7 is not needed as it is included, with newer revisions being included in newer versions of Windows since.

The first example is very simple; it shows some VBScript which uses the root WSH COM object «WScript» to display a message with an ‘OK’ button. Upon launching this script the CScript or WScript engine would be called and the runtime environment provided.

Content of a file hello0.vbs

WScript.Echo "Hello world"
WScript.Quit

WSH programming can also use the JScript language.

Content of a file hello1.js

WSH.Echo("Hello world");
WSH.Quit();

Or, code can be mixed in one WSF file, such as VBScript and JScript, or any other:

Content of a file hello2.wsf

<job>
<script language="VBScript">
  MsgBox "hello world (from vb)"
</script>
<script language="JScript">
  WSH.echo("hello world (from js)");
</script>
</job>

Security concerns[edit]

Windows applications and processes may be automated using a script in Windows Script Host. Viruses and malware could be written to exploit this ability. Thus, some suggest disabling it for security reasons.^[20] Alternatively, antivirus programs may offer features to control .vbs and other scripts which run in the WSH environment.

Since version 5.6 of WSH, scripts can be digitally signed programmatically using the Scripting.Signer object in a script itself, provided a valid certificate is present on the system. Alternatively, the signcode tool from the Platform SDK, which has been extended to support WSH filetypes, may be used at the command line.^[21]

By using Software Restriction Policies introduced with Windows XP, a system may be configured to execute only those scripts which are stored in trusted locations, have a known MD5 hash, or have been digitally signed by a trusted publisher, thus preventing the execution of untrusted scripts.^[22]

Available scripting engines[edit]

Note: By definition, all of these scripting engines can be utilised in CGI programming under Windows with any number of programmes and set up, meaning that the source code files for a script used on a server for CGI purposes could bear other file extensions such as .cgi and so on. The aforementioned ability of the Windows Script Host to run a script with multiple languages in it in files with a .wsh extension. Extended Html and XML also add to the additional possibilities when working with scripts for network use, as do Active Server Pages and so forth. Moreover, Windows shell scripts and scripts written in shells with enhanced capabilities like TCC, 4NT, etc. and Unix shells under interoperability software like the MKS Toolkit can have scripts embedded in them as well.

There have been suggestions of creating engines for other languages, such as LotusScript, SaxBasic, BasicScript, KiXtart, awk, bash, csh and other Unix shells, 4NT, cmd.exe (the Windows NT shell), Windows PowerShell, DCL, C, C++, Fortran and others.^[24]
The XLNT language^[25] is based on DCL and provides a very large subset of the language along with additional commands and statements and the software can be used in three ways: the WSH engine (*.xcs), the console interpreter (*.xlnt) and as a server and client side CGI engine (*.xgi).^[26]

When a server implementing CGI such as the Windows Internet Information Server, ports of Apache and others, all or most of the engines can be used; the most commonly used are VBScript, JScript, PythonScript, PerlScript, ActivePHPScript, and ooRexxScript. The MKS Toolkit PScript program also runs Perl. Command shells like cmd.exe, 4NT, ksh, and scripting languages with string processing and preferably socket functionality are also able to be used for CGI scripting; compiled languages like C++, Visual Basic, and Java can also be used like this. All Perl interpreters, ooRexx, PHP, and more recent versions of VBScript and JScript can use sockets for TCP/IP and usually UDP and other protocols for this.

Version history[edit]

The redistributable version of WSH version 5.6 can be installed on Windows 95/98/Me and Windows NT 4.0/2000. WSH 5.7 is downloadable for Windows 2000, Windows XP and Windows Server 2003. Recently^[when?], redistributable versions for older operating systems (Windows 9x and Windows NT 4.0) are no longer available from the Microsoft Download Center.

Since Windows XP Service Pack 3, release 5.7 is not needed as it is included, with newer revisions being included in newer versions of Windows since.

Microsoft windows based script host что это

Подлинный файл является одним из компонентов программного обеспечения Microsoft Windows, разработанного Microsoft.

Wscript.exe – это исполняемый файл (программа) для Windows. Расширение имени файла .exe – это аббревиатура от англ. слова executable — исполнимый. Необходимо запускать исполняемые файлы от проверенных производителей программ, потому что исполняемые файлы могут потенциально изменить настройки компьютера или нанести вред вашему компьютеру. Бесплатный форум с информацией о файлах может помочь вам разобраться является ли wscript.exe вирусом, трояном, программой-шпионом, рекламой, которую вы можете удалить, или файл принадлежит системе Windows или приложению, которому можно доверять.

Вот так, вы сможете исправить ошибки, связанные с wscript.exe

Информация о файле wscript.exe

Важно: Некоторые вредоносные программы маскируют себя как wscript.exe, особенно, если они расположены не в каталоге C:WindowsSystem32. Таким образом, вы должны проверить файл wscript.exe на вашем ПК, чтобы убедиться, что это угроза. Мы рекомендуем Security Task Manager для проверки безопасности вашего компьютера.

Лучшие практики для исправления проблем с wscript

Аккуратный и опрятный компьютер – это главное требование для избежания проблем с wscript. Для этого требуется регулярная проверка компьютера на вирусы, очистка жесткого диска, используя cleanmgr и sfc /scannow, удаление программ, которые больше не нужны, проверка программ, которые запускаются при старте Windows (используя msconfig) и активация Автоматическое обновление Windows. Всегда помните о создании периодических бэкапов, или в крайнем случае о создании точек восстановления.

Если у вас актуальные проблемы, попробуйте вспомнить, что вы делали в последнее время, или последнюю программу, которую вы устанавливали перед тем, как появилась впервые проблема. Используйте команду resmon, чтобы определить процесс, который вызывает проблемы. Даже если у вас серьезные проблемы с компьютером, прежде чем переустанавливать Windows, лучше попробуйте восстановить целостность установки ОС или для Windows 8 и более поздних версий Windows выполнить команду DISM.exe /Online /Cleanup-image /Restorehealth. Это позволит восстановить операционную систему без потери данных.

Следующие программы могут вам помочь для анализа процесса wscript.exe на вашем компьютере: Security Task Manager отображает все запущенные задания Windows, включая встроенные скрытые процессы, такие как мониторинг клавиатуры и браузера или записей автозагрузки. Уникальная оценка рисков безопасности указывает на вероятность процесса быть потенциально опасным – шпионской программой, вирусом или трояном. Malwarebytes Anti-Malware определяет и удаляет бездействующие программы-шпионы, рекламное ПО, трояны, кейлоггеры, вредоносные программы и трекеры с вашего жесткого диска.

Первые версии WSH поставлялись в виде отдельного компонента, опционально устанавливаемого в Windows, но уже начиная с Windows 98 WSH стал частью всех ОС Windows.

Windows Script Host – особый компонент операционной системы, который позволяет запускать скрипты, написанные на JS (Java Script), VBS (Visual Basic Script) и других языках. При неправильном его функционировании могут наблюдаться различные сбои во время запуска и работы Windows. Такие ошибки зачастую не могут быть исправлены простой перезагрузкой системы или графической оболочки. Сегодня поговорим о том, какие действия необходимо совершить для устранения неполадок в функционировании компонента WSH.

Исправляем ошибку Windows Script Host

Сразу стоит сказать о том, что если вы писали свой скрипт и при его запуске получили ошибку, то необходимо искать проблемы в коде, а не в системном компоненте. Например, вот такое диалоговое окно говорит именно об этом:

Такая же ситуация может возникнуть и в том случае, когда в коде имеется ссылка на другой скрипт, путь к которому прописан неверно либо данный файл вовсе отсутствует на компьютере.

Далее мы поговорим о тех моментах, когда при старте Windows или запуске программ, например, Блокнота или Калькулятора, а также других приложений, использующих системные ресурсы, появляется стандартная ошибка Windows Script Host. Иногда подобных окон может появиться сразу несколько. Случается такое после обновления операционной системы, которое может пройти как в штатном режиме, так и со сбоями.

Причины такого поведения ОС следующие:

Вариант 1: Системное время

Многие пользователи думают, что системное время, которое показывается в области уведомлений, существует только для удобства. Это не совсем так. Некоторые программы, обращающиеся к серверам разработчиков или к иным ресурсам, могут работать некорректно или вовсе отказаться функционировать по причине расхождений в дате и времени. Это же касается и Windows с ее серверами обновления. В том случае, если будет расхождение в вашем системном времени и времени сервера, то могут наблюдаться неполадки с апдейтами, поэтому на это стоит обратить внимание в первую очередь.

Нажимаем на часы в правом нижнем углу экрана и переходим по ссылке, указанной на скриншоте.

Далее идем на вкладку «Время по интернету» и жмем на кнопку изменения параметров. Обратите внимание, что ваша учетная запись должна обладать правами администратора.

В окне настроек устанавливаем галку в указанный на изображении чекбокс, затем в выпадающем списке «Сервер» выбираем time.windows.com и нажимаем «Обновить сейчас».

Если все пройдет успешно, то появится соответствующая надпись. В случае ошибки с превышением времени ожидания просто нажимаем кнопку обновления еще раз.

Теперь ваше системное время будет регулярно синхронизироваться с сервером времени Майкрософт и расхождения не будет.

Вариант 2: Служба обновлений

Windows – это очень сложная система, с множеством одновременно протекающих процессов, и некоторые из них могут повлиять на работу службы, отвечающей за обновление. Высокое потребление ресурсов, различные сбои и занятость компонентов, помогающих апдейту, «заставляют» службу совершать бесконечные попытки выполнить свою работу. Сам сервис также может сбоить. Выход здесь один: отключить его, а затем перезагрузить компьютер.

Вызываем строку «Выполнить» сочетанием клавиш Win+R и в поле с названием «Открыть» пишем команду, которая позволит получить доступ к соответствующей оснастке.

В списке находим «Центр обновления», кликаем ПКМ и выбираем пункт «Свойства».

В открывшемся окне жмем кнопку «Остановить», а затем ОК.

После перезагрузки служба должна запуститься автоматически. Стоит проверить, так ли это и, если она все еще остановлена, включить ее тем же способом.

Если после выполненных действий ошибки продолжают появляться, то необходимо поработать с уже установленными обновлениями.

Вариант 3: Некорректно установленные обновления

Данный вариант подразумевает удаление тех обновлений, после установки которых начались сбои в Windows Script Host. Сделать это можно как вручную, так и с помощью утилиты восстановления системы. В обоих случаях необходимо вспомнить, когда «посыпались» ошибки, то есть после какой даты.

Идем в «Панель управления» и находим апплет с названием «Программы и компоненты».

Далее переходим по ссылке, отвечающей за просмотр обновлений.

Сортируем список по дате установки, кликнув по шапке последней колонки с надписью «Установлено».

Выбираем нужное обновление, кликаем ПКМ и выбираем «Удалить». Также поступаем с остальными позициями, помня про дату.

Для перехода к данной утилите кликаем правой кнопкой мыши по значку компьютера на рабочем столе и выбираем пункт «Свойства».

Далее переходим к «Защите системы».

Нажимаем кнопку «Восстановление».

В открывшемся окне утилиты жмем «Далее».

Ставим галку, отвечающую за показ дополнительных точек восстановления. Необходимые нам поинты будут называться «Автоматически созданная точка», тип – «Система». Из них необходимо выбрать ту, которая соответствует дате последнего обновления (или того, после которого начались сбои).

Жмем «Далее», ждем, пока система предложит перезагрузиться и выполнит действия по «откату» к предыдущему состоянию.

Обратите внимание, что в этом случае могут быть удалены и те программы и драйвера, которые были установлены вами после этой даты. Узнать, произойдет ли это, можно нажав кнопку «Поиск затрагиваемых программ».

Вариант 4: Нелицензионная Windows

Пиратские сборки «винды» хороши лишь тем, что они совершенно бесплатны. В остальном же такие дистрибутивы могут принести массу проблем, в частности, некорректную работу необходимых компонентов. В этом случае рекомендации, приведенные выше, могут не сработать, так как файлы в скачанном образе уже были сбойными. Здесь можно только посоветовать поискать другой дистрибутив, но лучше воспользоваться лицензионной копией Windows.

Заключение

Решения проблемы с Windows Script Host довольно просты, и с ними справится даже начинающий пользователь. Причина здесь ровно одна: некорректная работа инструмента обновления системы. В случае с пиратскими дистрибутивами можно дать следующий совет: пользуйтесь только лицензионными продуктами. И да, правильно пишите ваши скрипты.

Исправлено: Windows Script Host доступ отключен на этом компьютере

Если вы получили этот доступ к Windows Script Host на этом компьютере, обратитесь к администратору для получения сообщения на вашем компьютере с Windows 10/8/7, тогда этот пост может вас заинтересовать. Сегодня мы увидим, как вы можете включить или отключить Windows Script Host.

Доступ к Windows Script Host отключен на этом компьютере

Сообщалось, что несколько «вредоносных программ HTML» используют объекты WSH, в результате чего те, кому эта функция не требуется, обычно ее отключают. Но отключение WSH не позволит пользователям запускать какие-либо сценарии, включая сценарии VBScript и JScript, которые используют эту технологию – и некоторым программам может потребоваться включить эту функцию.

Включить, отключить Windows Script Host

Чтобы включить или отключить Windows Script Host, введите regedit.exe в поле «Выполнить» и нажмите Enter, чтобы открыть редактор реестра.

Перейдите к следующей клавише:

HKEY_LOCAL_MACHINE Software Microsoft Windows Script Host Настройки

Нажмите OK и выйдите из Реестра. Если вы не видите эту запись, возможно, вам придется ее создать, так как она не существует по умолчанию в Windows.

Теперь вы больше не будете получать доступ к Windows Script Host на этом компьютере. Таким образом, вы можете включить или отключить Windows Script Host.

Вы также можете использовать наш FixWin для решения этой проблемы. Он предлагает исправление в 1 клик в разделе Дополнительные исправления.

Этот пост покажет вам, как исправить другие ошибки Windows Script Host в Windows 10.
