Более или менее продвинутые пользователи нередко пользуются командной строкой, ведь через неё можно влиять на большинство системных процессов. При использовании строки DISM, которая есть в седьмой и следующих версиях Windows, время от времени могут появляться сообщения об ошибке.
Это норма для любой программы, но наша задача — избавиться от неполадки, чтобы выполнить необходимую команду. Ошибка 87 DISM возникает по нескольким причинам, и в каждом случае есть свои пути её устранения.
Иногда пользователи могут столкнуться с ошибкой 87 в строке DISM
Давайте выясним, при каких обстоятельствах обычно появляется такое сообщение и как избавиться от него без посторонней помощи.
С чем связана ошибка 87?
Как правило, она напрямую относится к любым действиям, выполняемым с директорией WinSxS. Если вдруг в Windows пропадёт любой системный файл, он тут же будет восстановлен рабочей копией из этой папки. То есть, WinSxS это очень важная папка с документами.
И вот ошибка 87 возникает в тот момент, когда пользователь пытается проделать какие-то операции с папкой через DISM. А теперь давайте конкретнее рассмотрим ситуации, когда возникает эта неполадка, чтобы в зависимости от них узнать способы избавления от неё.
Ошибка 87 при проверке целостности системных файлов
Время от времени Windows 7, 8, 8.1 и даже последняя версия начинает некорректно работать. Иногда компьютер внезапно перезагружается или попросту часто зависает. В такой ситуации обычно пользователям советуют не только проверить ПК на вирусы, но и выяснить, нет ли каких-либо повреждений в системных файлах.
Чтобы произвести такую проверку, используется командная строка, где вводится sfc /scannow. Если всё хорошо, то пользователь получает соответствующий текст. Однако в некоторых случаях вы получите сообщение о том, что система нашла повреждённые файлы, но ничего не может с ними сделать.
В этот момент в игру вступает DISM — следует открыть его от имени администратора и ввести такие команды:
- DISM /Online /Cleanup-image /ScanHealth — если у вас седьмая версия Windows;
- Та же команда + DISM.exe /Online /Cleanup-image /RestoreHealth — две команды для Windows 8, 10. Первая необходима для поиска повреждений, вторая команда запускает их исправление.
Именно после первой комбинации из списка, которая разработана для седьмой версии системы, всплывает ошибка 87 в командной строке DISM с сопутствующим текстом «Параметр ScanHealth не распознан в этом контексте».
Как её исправить? Первое очень простое решение — проверить правильность ввода комбинации. Поскольку эта командная строка очень требовательна к каждому знаку, убедитесь, что ставите только один пробел перед каждым слешем.
Не помогло? Тогда вам следует скачать обновление под названием KB2966583 на сайте Майкрософт и установить его на своём компьютере.
После успешной установки вы сможете снова запустить командную строку DISM и выполнить восстановление целостности файлов Windows.
Ошибка 87 и попытки почистить директорию WinSxS
Иногда вышеупомянутую директорию, которая работает страховкой для всех самых важных файлов, пытаются уменьшить. Для чего? В большинстве случаев папка WinSxS занимает много места на диске — 5,7 и даже 8 и больше ГБ, что может не нравиться пользователям, особенно если свободной памяти и так не хватает.
Поэтому чтобы немного сэкономить место, можно удалить бэкап папки таким образом:
- Открывается DISM.
- Вводиться текст dism /online /cleanup-image /spsuperseded /hidesp.
Часто именно после этой команды выбивает ошибку 87 с таким текстом: «Параметр spsuperseded не распознан в этом контексте».
Что делать в таком случае? Проверьте работоспособность сервиса «Установщик модулей Windows». Если он нерабочий, установите его, запустите, и затем повторите вышеуказанные действия.
Если же это не помогло, значит, команда для удаления бэкапа уже выполнялась, и больше места вы сэкономить не сможете.
Теперь вы знаете, по каким причинам появляется ошибка 87 в командной строке Windows, и знаете, что делать для её исчезновения. Советуем быть аккуратными при пользовании подобными программами и внимательно следить за тем, в какие процессы вы вмешиваетесь, чтобы не навредить компьютеру.

Некоторые пользователи Windows часто пользуются командной строкой, чтобы вносить изменения во многие системные процессы и контролировать их. Строка DISM может помочь запустить нужный скрытый файл, системный процесс, восстановить хранилище с данными, утерянными из-за программного сбоя и т.д. Но иногда и в работе самой командной строки возникают ошибки, например, DISM /Online/Cleanup-Image /RestoreHealth: ошибка 87. Это нормально для системы Windows, но важно знать, как устранить эту проблему. Далее расскажем, почему возникает ошибка 87, и как исправить её разными способами.

- Из-за чего появляется ошибка 87?
- Попытка очистить папку WinSxS
- Попытка проверить целостность файлов системы
- Решение проблемы с ошибкой 87
- Отсутствие обновлений
- Недостаточно привилегий

Из-за чего появляется ошибка 87?
В любой операционной системе Windows есть особая директория WinSxS. Там хранятся копии всех важных системных файлов. Если, какой-то из оригинальных файлов будет повреждён или утерян, система автоматически восстановит его из этой директории. Таким образом, WinSxS является крайне важной директорией, без которой Windows может в какой-то момент полностью выйти из строя.
Ошибка 87 напрямую связана с директорией WinSxS. Она возникает, когда пользователь пытается внести какие-либо изменения в эту папку. Рассмотрим действия, после которых вы можете увидеть эту ошибку на своём экране.
Попытка очистить папку WinSxS
Директория со всеми важными файлами может занимать около 7-8 Гигабайтов, поэтому некоторые пользователи пытаются удалить все бэкапы с компьютера, чтобы получить больше свободного места.
Для этого нужно:
- Зайти в пуск и ввести в поисковой строке «DISM».
- Запустить DISM.
- Ввести команду dism /online /cleanup-image /spsuperseded /hidesp.
В этом случае ошибка будет сопровождаться объяснением, что «spsuperseded» на компьютере не распознан. Проблема, скорее всего, в «Установщике модулей Windows». О нём расскажем далее.
Попытка проверить целостность файлов системы
Если компьютер начал плохо работать, спонтанно перезагружаться или выключаться, проблема может быть не только в вирусах. Часто причиной становится повреждение файлов системы. В DISM при помощи команды «sfc /scannow» можно выполнить автоматическое сканирование и восстановление. Но, в некоторых случаях, система выявляет повреждение файлов, но сделать с этим ничего не может.
Тогда приходится проводить восстановление вручную:
- Запустить DISM.
- Ввести команду сканирования.
- Ввести команду восстановления.
Для Windows 7 достаточно ввести одну команду: «DISM /Online /Cleanup-image /ScanHealth». Если вы пользуетесь более новыми версиями ОС, к этому коду нужно добавить вторую часть «DISM.exe /Online /Cleanup-image /RestoreHealth».
При попытке проверки файлов и возникает ошибка 87. В этом случае проблема часто заключается в отсутствии обновлений. Как её решить, расскажем далее.
Решение проблемы с ошибкой 87
Существует несколько причин, вызывающих ошибку 87. Во всех случаях исправить проблему достаточно просто, поэтому рассмотрим каждый случай подробнее.
Отсутствие обновлений
Ошибка часто возникает при попытке восстановить системные файлы, если некоторые модули системы не обновлены. В данном случае вам требуется найти на официальном сайте Microsoft обновление KB2966583. Оно распространяется бесплатно и почти ничего не весит. Найдите подходящий под вашу версию ОС файл, выберите язык «русский», скачайте обновление, запустите и следуйте дальнейшим инструкциям в инсталляторе.
Также ошибка 87 возникает из-за отсутствия других обновлений. Обычно, система Windows обновляется автоматически. Но, если вы отключите эту функцию, то со временем некоторые функции и программы начнут работать некорректно. Введите в поисковой строке «Центр обновлений Windows» и проверьте последние обновления.
Недостаточно привилегий
Использовать DISM могут только те пользователи, которые обладают правами администратора. Если вы запустили консоль, как обычный пользователь, то при попытке ввести команду она покажет вам ошибку 87. Чтобы запустить командную строку в режиме администратора, найдите её в перечне программ. После этого нажмите правой кнопкой мыши и в открывшемся списке выберите пункт «Запуск от имени администратора».
Проблема с системными службами
При выполнении некоторых команд в DISM задействуется системная служба «Установщик модулей Windows». Из-за программных сбоев она иногда отключается, что не позволяет выполнять некоторые команды.
Найдите «Службы» через поисковую строку и найдите в списке нужную службу.
Нажмите на неё правой кнопкой мыши и выберите «Свойства». Если «Установщик модулей Windows» остановлен, как на скриншоте снизу, нажмите на «Запустить».
Ошибка в синтаксисе
Распространённая ошибка, допускаемая по невнимательности. Проверьте правильность набранной команды. Обратите внимание, что перед каждым знаком «/» должен стоять пробел. На эту причину указывают следующие описания к ошибке 87:
- Параметр не распознан в контексте;
- Неизвестный параметр.
DISM stands for Deployment Image Service and Management, and you can find DISM in Windows 7/8/10/11 and Windows Server R2 as a preinstalled tool to provide services related to the recovery and repair of Windows images.
You can access the DISM tool from Windows PowerShell or the Command Line of your computer. When a Windows image becomes inoperable, the DISM tool can update files and repair problems.
