Windows logs cbs что это за папка

Have you heard about CBS.log? In this post, you will get a detailed introduction of CBS.log Windows 10. Besides, MiniTool software provides several feasible methods to help you fix CBS.log corrupt issue.

You may be not familiar to CBS.log file, but you might experience certain problems related to it. In the following contents, I will give you detailed information about CBS.log file and provide some effective solutions to CBS.log corrupt issue.

Without further ado, let’s have a close look at CBS.log at first.

What Is CBS.log

CBS refers to Component-Based Servicing. Some components might be installed or uninstalled during Windows update, and CBS.log is a file that includes logs about these involved components. This file logs detailed information from your most recent Windows installed updates, and thus it can be used for troubleshooting issues related to your updates.

What’s more, the built-in tool System File Checker also writes to this log file. In other words, when you use SFC.exe, the details of involved verification operation and repair operation will be written to the CBS.log file.

Where is the CBS.log file stored on your device?

Actually, you can find it in the path of %windir%LogsCBSCBS.log. The %windir% means the directory where your Windows is installed, typically C:Windows. So, the common location of CBS.log file is C:WindowsLogsCBSCBS.log.

Why and How to Read CBS.log

SFC.exe is a nice utility to resolve various issues caused by corrupted or missing system files. However, sometimes the problematic system files cannot be repaired by SFC scan. When the scanning process completes, you might receive the following message: Windows Resource Protection found corrupt files but was unable to fix some of them. Details are included in the CBS.Log windirLogsCBSCBS.log.

This message refers users to CBS.log file but doesn’t give access to view it, which makes users frustrated. How to read CBS.log? Commonly, we can go to the directory where CBS.log file is stored and double-click it to open it. However, things might be a little complicated if you want to read SFC logs only.

Don’t worry. To analyze the log file generated by SFC.exe program, you can follow the steps below.

Step 1: Press Windows + R to open Run window.

Step 2: Input cmd and press Ctrl + Shift + Enter to run Command Prompt as administrator.

Step 3: Type the following command line and press Enter to execute it: findstr /c:»[SR]» %windir%LogsCBSCBS.log >»%userprofile%Desktopsfclogs.txt

In CBS.log file, every SFC.exe program entry has a tag of [SR]. By performing this command, a new file named sfclogs will be created on your Desktop and all the SFC logs will be filtered out and stored altogether in this file.

Open this file with Notepad, and you can view and analyze the details of the scanned system files and information about the files that couldn’t be repaired during SFC scan.

Is It Safe to Delete CBS.log File?

It is harmless to leave the CBS.log file on your drive and you can let it alone. But sometimes, you may find that your drive is heavily fragmented after Windows update and the CBS.log is eating up your disk space. Under this situation, you might need to delete the CBS.log file.

You can feel free to delete it as this operation does no harm to your computer.

When you are trying to delete CBS.log file, you might receive an error saying that this file is in use. The Windows Update service might be responsible for this issue, because it is always ready to write update information to CBS.log file. So, you have to disable it before deleting the file.

Here is a tutorial on how to disable the service and then delete CBS.log file.

Step 1: After invoking Run dialog, input services.msc and press Enter to open Services app.

Step 2: Locate Windows Update service. Right-click the service and choose Stop to disable it temporarily. Then, exit the window.

Step 3: Open your File Explorer and go to your system drive. Then, navigate to Windows > Logs > CBS folder. You may need to check Hidden items option under View tab in tool bar to show Logs folder.

Step 4: Open CBS folder, and delete the CBS.log file or all files in it.

Step 5: After you have deleted the log file safely, open the Service app again to enable Windows Update service.

After that, the file will be recreated with everything it needs but won’t largely take up your disk space.

Cbs.Log Windows 10 FAQ

При проверке целостности системных файлов с помощью утилиты SFC пользователь может получить сообщение об обнаружении ряда повреждённых файлов, восстановить которые не удалось. Данные о таких файлах система записывает в файл CBS.log, открыть который также не удаётся по различным причинам (в частности из-за повреждения данного файла). В данном материале я разберу, что предпринять в такой ситуации, и каким образом исправить дисфункцию windirLogsCBSCBS.log повреждён на вашем ПК

Что такое CBS.log?

Системная утилита SFC, предназначенная для проверки целостности системных файлов ОС Виндовс, записывает данные по проверке и восстановлению файлов в файл CBS.log. Последний расположен по адресу %windir%LogsCBS, и может быть недоступным при попытке просмотреть его содержимое стандартным способом (через «Блокнот», файловый менеджер и др.).

Это может быть связано с закрытием доступа к данному файлу со стороны Виндовс, а также с повреждением данного файла по различным причинам (вирусы, осыпание диска, другие релевантные причины).

Для решения возникшей проблемы с повреждением windirLogsCBSCBS.log необходимо воспользоваться алгоритмом, который я приведу ниже.

Как исправить ошибку WindirLogsCBSCBS.log

В случае, если доступ к файлу закрыт на уровне системных настроек Виндовс, рекомендуется, запустит командную строку с правами администратора, в ней набрать:

после чего нажать на ввод. Файл данного лога будет сохранён на рабочем столе вашего PC, и вы сможете его просмотреть через самый обычный «Блокнот». Во время данного просмотра, в частности, вы можете увидеть, какие именно файлы утилита SFC посчитала повреждёнными, и скопировать их из стабильной системы.

Если же после запуска и работы утилиты SFC система выдала текст о невозможности восстановления ряда файлов, и записи информации об них в файле CBS, тогда выполните следующее:

Запустите командную строку от имени админа, и в ней последовательно наберите (обратите внимание на пробелы, они должны быть так, как приведено мной ниже:

затем

а уже потом

Дождитесь полного окончания данных процедур (могут занять полчаса-час), а затем перезагрузите ваш PC. После этого всё должно стабильно работать.

Альтернативные решения при повреждении CBS.log

В ряде случаев причиной возникновения проблемы является действие вирусных программ и осыпание диска. В первом случае рекомендуется проверить ваш PC с помощью соответствующего антивирусного инструментария (например, Доктор Веб Кюрейт, AdwCleaner и других аналогов). Затем перезагрузить ПК, и постараться вновь получить доступ к данному лог-файлу.

В случае осыпания диска, рекомендую воспользоваться такими утилитами как «Victoria HDD», «HDD Regenerator» и других, которые проверят ваш диск на наличие битых секторов, и при возможности восстановят его.

Заключение

В данном материале мной было разобраны способы того, как исправить повреждённый файл по адресу windirLogsCBSCBS.log. В большинстве случаев достаточно приведённых мной выше команд, чтобы полноценный доступ к данному файлу был восстановлен, и вы получили в пользование всю статистическую информацию, находящуюся в данном файле.
