Что за ошибка 87 в командной строке windows 7

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.

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.

• Способ 1: Запуск cmd с правами администратора
• Способ 2: Проверка написания
• Способ 3: Установка обновления
• Способ 4: Восстановление DISM
• Вопросы и ответы

Способ 1: Запуск cmd с правами администратора

Нередко ошибку удается исправить, просто запустив «Командную строку» с администраторскими полномочиями. Для этого найдите приложение через «Пуск», кликните по нему правой кнопкой мыши и выберите пункт «Запуск от имени администратора».

В «десятке» это можно сделать и через расширенное меню «Пуска».

Впишите команду еще раз.

Способ 2: Проверка написания

Часто пользователи не придают значения правильному написанию команды. В результате, даже если там нет ошибок, отсутствие, например, пробелов или косых черточек уже не позволит выполнить команду. Проверьте правильность ее написания, при необходимости скопируйте строчку ниже и вставьте в консоль клавишами Ctrl + V:

DISM.exe /Online /Cleanup-image /RestoreHealth

Способ 3: Установка обновления

В Windows 7, где действие команд DISM.exe /Online /Cleanup-image /ScanHealth и DISM.exe /Online /Cleanup-image /RestoreHealth объединено в одну (в первую), устранить ошибку 87 можно установкой обновления, без которого обе команды не работают в принципе. Скачивается пакет с официального сайта Microsoft по ссылке ниже.

Скачать KB2966583 с официального сайта Microsoft

1. Выберите установленную на вашем ПК операционную систему и нажмите кнопку «Загрузите пакет».



2. Укажите подходящий язык и кликните «Download».



3. Скачанный пакет запустите и дождитесь завершения проверки.



4. В ответ на вопрос об установке нажмите «Да».



5. Начнется инсталляция, которая не займет много времени.



6. Закройте установочное окно.

Попробуйте снова запустить команду в консоли.

Вероятно, если DISM был критически поврежден в результате действий пользователя, внутренних ошибок, использования «кривой» сборки Windows, есть смысл восстановить его работоспособность. Сделать это не очень просто, и может потребоваться создание загрузочной флешки. Более подробно этот процесс в Windows и в среде восстановления был рассмотрен в статье по следующей ссылке.

При использовании любительской сборки советуем перейти на чистую, а еще лучше лицензионную версию.
