Ошибка 0x803c0103 возникает при запуске средства устранения неполадок Центра обновления Windows 10. Как правило, пользователи сталкиваются с этой ошибкой в том случае, если у них не получается установить новые (или отложенные) обновления для своей системы и они решаются запустить уже упомянутое средство устранения неполадок.
Что вызывает появление ошибки 0x803c0103
Ошибка 0x803c0103 — крайне тревожная проблема, а все из-за того, что она появляется в средстве, которое должно как раз устранять эти самые проблемы. Завидев такой код перед собой и потеряв возможность обновлять свою ОС, многие пользователи впадают в панику — не нужно этого делать! Для начала нам с вами нужно понять, почему вообще возникает 0x803c0103.
- Повреждения системных файлов. Средство устранения неполадок и Центр обновления для своей работы задействуют безумное количество всевозможных системных файлов Windows 10. Если с этими файлами что-то произойдет, то есть шанс, что ни средство, ни Центр обновления не смогут корректно выполнять возложенные на них задачи. К счастью, Майкрософт не дураки — они оснастили свои ОСы специальными инструментами, которые способны восстанавливать целостность системных файлов.
- Компоненты Центра обновления находятся в «мертвой петле». В некоторых случаях службы и компоненты Центра обновления могут наглухо зависнуть, так сказать, в своеобразной мертвой петле. Открывая Центр обновления или средство устранения неполадок, система пытается получить доступ к повисшим элементам, однако ей это не удается — пользователь получает соответствующую ошибку, например, 0x803c0103.
- Банальный баг операционной системы. Бывает и такое, что средство устранения неполадок показывает вам ту или иную ошибку просто из-за того, что в Windows 10 возник какой-то странный баг, который препятствует нормальной работе некоторых компонентов ОС. Как правило, избавиться от такого бага можно с помощью элементарной перезагрузки.
Как избавиться от ошибки 0x803c0103
Мы настоятельно рекомендуем выполнять методы в том порядке, в котором мы указали их ниже. Поверьте, вам действительно не нужно переустанавливать свою ОС всякий раз, когда у вас не получается установить то или иное обновление для Windows 10.
Метод №1 Перезагрузка ПК
Самый простой и, на удивление, эффективный метод устранения ошибки 0x803c0103 — элементарная перезагрузка компьютера. Попробуйте перезапустить свой ПК, после чего снова запустите средство устранения неполадок и проверьте наличие ошибки. Кроме того, после перезагрузки можете сразу запустить обновление ОС: проблемы с установкой апдейтов могли разрешиться сами собой.
Метод №2 SFC и DISM — средства восстановления Windows
Средство устранения неполадок и Центр обновления могут перестать работать, если некоторые из системных файлов Windows 10 были повреждены, изменены, перемещены или удалены. Кстати, последние четыре пункта могут произойти по вине вирусов и вредоносного программного обеспечение — мы рекомендуем вам прямо сейчас запустить сканирование антивирусом. Так или иначе повреждение системных файлов необходимо как-то исправлять, верно? Тут на выручку идут такие полезные утилиты, как SFC и DISM.
Первая утилита сканирует системные файлы на наличие повреждений и устраняет последние, если это возможно, вторая — ищет повреждения в хранилище компонентов и образе системы, после чего точно также пытается их устранить. Пользоваться обеими утилитами очень и очень просто — мы покажем вам, как это сделать.
SFC для восстановления системных файлов
- Нажмите на клавиатуре комбинацию Win+R, чтобы открыть окошко «Выполнить».
- Вставьте в пустую поисковую строчку окна значение «CMD» (без кавычек) и нажмите комбинацию CTRL+SHIFT+ENTER.
- Открыв перед собой системную консоль (от имени администратора), вставьте в нее команду «sfc /scannow» (без кавычек) и нажмите ENTER.
- Подождите несколько минут (или дольше), ознакомьтесь с результатами работы утилиты и перезагрузите компьютер.
DISM для восстановления хранилища компонентов и образа системы
- Нажмите на клавиатуре комбинацию Win+R, чтобы открыть окошко «Выполнить».
- Вставьте в пустую поисковую строчку окна значение «CMD» (без кавычек) и нажмите комбинацию CTRL+SHIFT+ENTER.
- Открыв перед собой системную консоль (от имени администратора), вставьте в нее команду «Dism /Online /Cleanup-Image /CheckHealth» и нажмите ENTER.
- Ознакомьтесь с результатами проверки, после чего вставьте в консоль команду «Dism /Online /Cleanup-Image /ScanHealth» и нажмите ENTER.
- Снова ознакомьтесь с результатами сканирования, затем вставьте команду «Dism /Online /Cleanup-Image /RestoreHealth» и нажмите ENTER.
- Подождите завершения восстановления и перезагрузите ПК.
Важно отметить, что для выполнения некоторых из указанных выше команд может потребоваться достаточно большое количество времени. Проще говоря, вам, возможно, придется набраться терпения. Как только закончите работать с SFC и DISM, проверьте, была ли устранена ошибка 0x803c0103 в средстве устранения неполадок и исчезли ли проблемы в Центре обновления Windows 10.
Метод №3 Запуск точки восстановления системы
Раньше ни со средством устранения неполадок, ни с Центром обновления не возникало никаких проблем? Тогда, возможно, вы имеете дело с конфликтом, который возник между системными компонентами Windows 10 и сторонним программным обеспечением. Рекомендуем воспользоваться точкой восстановления, чтобы вернуть свою систему к более стабильному состоянию.
- Нажмите Win+R для вызова окошка «Выполнить».
- Пропишите в пустой строке значение «control» и нажмите ENTER.
- Измените режим просмотра на «Крупные значки».
- Перейдите в Панели управлении в раздел «Восстановление».
- Кликните на пункт «Запуск восстановления системы».
- Теперь нажмите на кнопку «Далее», выберите подходящую точку восстановления и нажмите еще раз «Далее».
- И наконец-то, нажмите на кнопку «Готово», чтобы начать восстановления системы.
Важно отметить, что во время восстановления ОС ваш компьютер автоматически перезагрузится. Как только зайдете в систему, проверьте наличие ошибки 0x803c0103.
Метод №4 Починка компонентов Центра обновления
Неполадки в средстве устранения неполадок и самом Центре обновления могли быть вызваны некорректной работой тех или иных компонентов этого самого Центра обновления. Решается такая проблема с помощью сброса компонентов ЦО. Сброс компонентов ЦО Windows 10 — это достаточно простой процесс, несмотря на заявления некоторых пользователей в сети.
Осуществить подобный сброс можно как вручную, так и в полуавтоматическом режиме. Мы рекомендуем вам не тратить свое время, и воспользоваться вторым вариантом.
Полуавтоматический сброс компонентов Центра обновления
- Создайте на своей Рабочем столе (или любом другом удобном вам месте) самый обычный текстовый файл. Не знаете, как это сделать? Нажмите ПКМ на пустое место и выберите пункты «Создать→Текстовый документ».
- Откройте созданный файл и вставьте в него следующий скрипт:

Windows 10 Updates are occasionally quite troublesome. There are dozens of different update-related errors plaguing users from day one.
And, since updates are mandatory in Windows 10, chances are you’ll run into one of the errors sooner or later. After the error occurs, most users will reach for the built-in troubleshooter.
However, there seems to be an error with the Update Troubleshooter itself and it goes by the 0x803c0103 code.
If this or similar errors bother you while running the Update Troubleshooter, make sure to try the steps below in order to resolve it.
How can I fix update error 0x803c0103?
1. Run SFC and DISM
Let’s start with the usual solution whenever any system tool fails to deliver. If some of the essential Windows files are corrupted, chances are that certain built-in features will get broken.
This isn’t uncommon for Windows Update for Windows 10, which tends to break PCs left and right. Users who experienced the update error and then tried running the troubleshooter, have tasted this first hand.
When something like this happens, we need to check the system for corruption. Whether the last unoptimized update brought this upon you, or it’s something else at hand – it doesn’t matter.
What matters is that you have all the tools you need to fix it right there. The first tool is the System File Checker, which scans and resolves system corruption.
The other one takes the same task to another level and it’s called Deployment Image Servicing and Management or DISM. They work best when combined.
Here’s how to run SFC and DISM on your PC:
- In the Windows Search bar, type cmd. Right-click click on Command Prompt and run it as admin.
- In the command-line, type sfc/scannow and press Enter.
- After its done, type the following command and press Enter after each:
- DISM /online /Cleanup-Image / ScanHealth
- DISM /Online /Cleanup-Image /RestoreHealth
- When the procedure ends, restart your PC.
Alternatively, you can rely on third-party optimizing tools that can restore your PC from crashes or errors like the one here.
Plus, you have the benefits of optimizing your PC processes and repairing various system or program malfunctions.
2. Reset Update services
If we avoid the premise that the update in itself is badly administered, we are left with some internal issues you should check up.
Namely, maybe the update files stored on your PC are corrupted or the associated services won’t start when needed.
If that’s the case, we suggest resetting the said services and redownloading the update files stored in the SoftwareDistribution folder. Here’s what you need to do:
- In the Windows Search bar, type cmd.
- Right-click the Command Prompt and run it as an administrator.
- In the command-line, type the following commands and press Enter after each:
- net stop wuauserv
- net stop bits
- net stop cryptsvc
- ren C:WindowsSoftwareDistribution SoftwareDistribution.old
- ren C:WindowsSystem32catroot2 Catroot2.old
- net start wuauserv
- net start bits
- net start cryptsvc
After that, check for updates again.
3. Use a downloadable troubleshooter
If the built-in Update Troubleshooter won’t work, we suggest using a downloadable alternative provided by Microsoft. This tool should, in theory, completely fill in for the built-in Update Troubleshooter.
It doesn’t require installation and you can run it as soon as it’s downloaded. It should scan for update-related errors and fix them accordingly.
If you’re not sure where to get it and how to run it, here’s the whole step-by-step explanation:
- Download Windows Update Troubleshooter from here.
- Right-click on the tool and run it as administrator.
- Follow the instructions and restart your PC after the fix is applied.
4. Reset this PC
Finally, if none of the previous steps helped you resolve the error at hand, we suggest resetting your PC to factory values.
I’ve done it myself multiple times after an insider update that completely ruined my system or made some of the key features inaccessible.
After the reset, everything worked just fine. And, most importantly, you get to keep your files and settings. Errors like the 0x803c0103 usually affect users who upgraded over Windows 7/8.1.
So a clean reinstallation is another option you might consider.
Here’s how to reset your PC to factory settings:
- Press Windows key + I to summon the Settings app.
- Open the Update & Security section.
- Select Recovery from the left pane.
- Under Reset this PC, click Get started.
- Keep your files and start the restoration process.
With that said, we can conclude this article. Hopefully, one of the enlisted steps helped you address the troubleshooter error 0x803c0103.
In case you have any questions or suggestions, feel free to tell us in the comments section below.
If completely removing it from your PC is required, be sure to use the best uninstaller software of the moment.

Some Windows 10 users are reporting that they always end up seeing the 0x803c0103 error when attempting to run the Windows Update Troubleshooter in order to resolve an issue with one of the pending Windows updates that are waiting to be installed.
After investigating this particular issue, it turns out that there are a couple of underlying issues that might be triggering this error code. Here’s a shortlist of potential culprits that might be responsible for this issue:
- System File Inconsistency – One of the most common causes that will trigger this issue is a common system file inconsistency that ends up affecting the updating function or the Windows Update troubleshooter. In this case, you can most likely fix the issue by running SFC and DISM scans in order to fix corrupted OS data. In more serious circumstances, you might need to go for a repair install or repair install.
- Windows Update is stuck in a limbo state – One less frequent scenario that will cause this issue is the Windows Update service that is stuck in a limbo state. In this case, you can resolve the issue by resetting every Windows Update component with a specialized agent or by doing it manually from an elevated CMD.
Now that you are intimately familiar with every cause of this error code, here’s a list of verified fixes that should allow you to resolve the 0x803c0103 error:
Method 1: Running SFC and DISM Scans
As it turns out, one of the most common instances that will trigger the 0x803c0103 error when running the Windows Update troubleshooter is a system file corruption that is affecting the auto-updating function of Windows installation.
If this scenario looks like it could be applicable, you should start by running a couple of scans with two built-in utilities – System File Checker (SFC) and Deployment Image Servicing and Management(DISM).
While both SFC and DISM share some similarities, our recommendation is to run both scans in quick succession in order to improve your chance of fixing the corrupted system files.
If this scenario is applicable, start with a simple SFC scan.
Note: Keep in mind that this tool is entirely local and will not require you to be actively connected to the internet.
Important: After you initiate this procedure, it’s very important to not close the CMD window even if the utility looks like it froze. Wait patiently until the process is complete, as interrupting the operation might cause logical errors on your HDD or SSD.
After the SFC scan is completed successfully, reboot your computer and see if the issue is fixed once the next computer startup is complete.
If the same 0x803c0103 Windows Update Troubleshooter issue is still occurring, deploy a DISM scan and follow the on-screen prompts to complete the operation.
Note: A key difference between SFC and DISM is that DISM uses a sub-component of Windows Update to download healthy equivalents to replace corrupted system files. Because of this, you need to make sure that you have reliable Internet before initiating this operation.
Once the DISM scan has been completed successfully, restart your computer once again and see if the 0x803c0103 error is now fixed.
If the Windows Update Troubleshooter is still not fixed, move down to the next potential fix below.
Method 2: Reset every Windows Update Component
If repairing the system files didn’t allow you to fix the issue, you’re likely dealing with a persisting bug that is affecting the Windows Update troubleshooter.
Since you were unable to repair the Troubleshooter via DISM or SFC, the next best thing you can do is deploy the same repair strategies in order to reset every Windows Update component that might be causing issues with your pending Windows updates.
By far, the most common instance that will cause this kind of issue is one or more WU (Windows Update) components that are currently stuck in a limbo state (they’re neither open nor closed). If this scenario is applicable, you will be able to fix the problem by resetting all WU components that are involved in the updating process.
Here are two different methods that you can follow in order to reset all Windows Update components:
A. Resetting WU via the WU Agent
- Start by visiting this Microsoft Technet download page and download the Reset Windows Update Agent script.
Downloading the Windows Update Reset Agent - After the download is finally complete, extract the zip archive with a utility like WinRar, WinZip, or 7Zip and paste it into an easy to access location.
- Double-click on the ResetWUENG.exe file, click Yes at the User Account Control, and then follow the instructions to run the script on your computer. After you do so, it will reset all your WU components.
- Once the process is complete, restart your computer and see if you’re able to install the failing update once the next startup sequence is complete.
Resetting WU via elevated CMD
- Start by pressing Windows key + R to open up a Run dialog box. Then, type “cmd” inside the text box and press Ctrl + Shift + Enter to open up an elevated Command Prompt.
Opening an elevated Command Prompt Note: When you see the UAC (User Account Control) prompt, click Yes to grant administrative privileges.
- Once you’re inside the elevated Command Prompt, type the following commands in order and press Enter after each one to stop all WU related services:
net stop wuauserv net stop cryptSvc net stop bits net stop msiserver
Note: Just so you know what you’re actually instructing the terminal to do, these commands will stop the Windows Update Services, MSI Installer, Cryptographic services, and BITS services.
- After every relevant service has been stopped, run the following commands to clear and rename SoftwareDistribution and Catroot2 folders:
ren C:\Windows\SoftwareDistribution SoftwareDistribution.old ren C:\Windows\System32\catroot2 Catroot2.old
Note: These folders are responsible for holding updated files use by the WU component. Renaming these folders will force your OS to create new healthy equivalents that will not be affected by corruption.
- Now that the folders have been cleared, run the following commands to re-enable the services that we’re previously disabled:
net start wuauserv net start cryptSvc net start bits net start msiserver
- Restart your computer once again and see if the issue has been resolved at the next computer startup.
If the same issue is still occurring even after you have successfully refreshed every Windows Update component, move down to the next potential fix below.
Method 3: Performing a Repair Unstall or Clean Install
If none of the methods above have allowed you to resolve the 0x803c0103 error when running the Windows Update Troubleshooter, you can conclude that your issue is caused by an underlying system corruption issue that can’t be fixed conventionally (with DISM and SFC scans).
Several users that were facing a similar issue have reported that the issue was fixed after they refreshed every Windows component. This can either be achieved by an in-place repair (repair install) or by a clean install.
Going for a clean install is a more straight-forward solution, but the main drawback is that it won’t allow you to keep your personal files (applications, games, personal media, etc.) unless you back them out first.
On the other hand, if you decide to go for a repair install, the procedure is a little more tedious, but the main advantage is that you get to keep all your personal files including applications, games, personal media, and even some user preferences.
