Sometimes, you might encounter the USB driver error code 52: Windows cannot verify the digital signature for the drivers required for this device. Luckily, you can fix it by yourself. In this article, MiniTool Partition Wizard puts together some solutions to this issue and hope you can benefit from them.
Windows Digital Signatures
Based on Microsoft public key infrastructure technology, the Windows digital signatures are implemented to verify the identity of the software publisher or the driver vendor. The digital signature can protect your Windows from potential threats and infections of some malicious programs.
According to the explanation from Microsoft, Windows uses a valid digital signature to verify some information, including:
- The file, or the collection of files (such as a driver package), is signed.
- The signer is trusted.
- The certification authority that authenticated the signer is trusted.
- The collection of files was not altered after it was published.
In order to be installed and run on the latest Windows operating system, the drivers and programs must be digitally signed. However, there are still some legitimate programs or drivers that are not signed, and you may encounter certain problems while installing them.
About Windows Cannot Verify the Digital Signature Code 52
Sometimes, your USB ports might fail to recognize any hardware connected to your device, and you will see the error code 52 in the properties of the USB driver. The USB driver code 52 is a typical error related to the digital signature. It commonly occurs after updating or upgrading Windows and comes up with the following error message:
Windows cannot verify the digital signature for the drivers required for this device. A recent hardware or software change might have installed a file that is signed incorrectly or damaged, or that might be malicious software from an unknown source. (Code 52)
Besides, you might receive some other different error messages related to Windows digital signature, such as “Windows cannot verify the digital signature for this file. (0xc0000428)”, “Digital Signature not found”, and so on.
If you receive the digital signature error unluckily, take it easy. Some feasible solutions reported by the users are listed in the following contents, and you can work your way down the list until you fix the issue effectively.

Windows Cannot Verify the Digital Signature FAQ
Can I install a driver without a digital signature?
To install a driver and make it work properly on your computer, the driver should be officially signed. But sometimes, you may want to install a drier without a digital signature. Yes, you can force an unsigned driver to install, but it may take some time. For the detailed information, you can check this guide.
How do I fix an invalid digital signature?
If you encounter the invalid digital signature installation error, you can try the following solutions:
- Make sure the downloaded executable is unblocked.
- Install the certificates manually through the properties of the executable file.
- Consult your group policy admin to temporarily disable restriction for the authentication of certificates.
What is the difference between signed and unsigned drivers?
The signed driver with a correct digital signature indicates that it is not damaged, corrupted, manipulated, or changed, and it is safe to use. It can be installed and work properly on Windows. The unsigned driver will be considered as a potentially malicious item by the system and it cannot be installed properly.
A signed driver might also turn to unsigned if its signature becomes invalid due to any tampering or changing.
Windows provides different error codes for different types of errors. These codes can be useful in identifying the root cause of the problem and then resolving it. You may get the following error while running a device/component in Windows 11/10:
Windows cannot verify the digital signature for the drivers required for this device. A recent hardware or software change might have installed a file that is signed incorrectly or damaged, or that might be malicious software from an unknown source. (Code 52)
This error was prevalent in Windows 7 but has been reported on Windows 10 and even Windows 11 systems. Most modern components of the PC are automatically installed by Windows 10/11. However, some specific hardware devices may have corrupted drivers or nonstandard drivers might have been installed. As a result, Windows may display Error code 52.

По умолчанию Windows требует, что все драйверы устройств были подписаны валидной цифровой подписью. Если цифровая подпись драйвера отсутствует, или подписывающий сертификат отозван, Windows отклонит установку такого драйвера. Если вам нужно установить в Windows какой-то старый драйвер без цифровой подписи, рекомендуется самостоятельно подписать драйвер с помощью самоподписанного сертификата (сложный, но безопасный вариант). В крайнем случае можно полностью отключить проверку цифровой подписи драйверов в Windows (хотя это и менее безопасный способ). В этой статье мы рассмотрим, как отключить проверку подписи драйверов и установить неподписанный драйвер в Windows 10 и 11.
Содержание:
- Режим загрузки Windows без проверки подписи драйвера
- Отключить режим проверки подписи драйверов из командной строки Windows
- Разрешить установку неподписанных драйверов через групповую политику
В нашем примере при попытке установить драйвер видеокарты без цифровой подписи с помощью команды
pnputil.exe /add-driver c:\drivers\*.inf /subdirs /install
или из проводника Windows, появляются ошибки вида:
Error 0xE000022F: The third-party INF does not contain digital signature information.
Error 0x800B010C: A certificate was explicitly revoked by its issuer.
Режим загрузки Windows без проверки подписи драйвера
Один из отладочных режимов загрузки Windows позволяет загружать операционную систему, игнорируя проверку подписи драйверов. Чтобы загрузить Windows в таком режиме, зажмите кнопку
Shift
и нажмите кнопку
Перезагрузка
в меню Пуск.
Windows запустится в среде восстановлений Windows RE, где нужно выбрать Troubleshoot -> Advanced Options -> Startup Settings -> Restart.
Компьютер перезагрузится еще раз и перд вами появится список режимов загрузки Windows. Нажмите клавишу
F7
(или
Fn+F7
на ноутбуках), чтобы загрузить Windows с включенной опцией Disable driver signature enforcement.
Windows загрузится с отключенной проверки цифровой подписи драйвера. При установке неподписанного драйвера появится предупреждение системы безопасности Windows:
Windows can't verify the publisher of this driver software The driver software you're attempting to install does not have a valid digital signature that verifies who published it, and could potentially be malicious software. You should only install driver software from publishers you trust. How can I decide which device software is safe to install?
Чтобы подтвердить установку драйвера, выберите Install this driver software anyway (
Все равно установить этот драйвер
).
Драйвер будет установлен, но в диспетчере устройств устройство с неподписанным драйвером может отображаться с восклицательным знаком и кодом ошибки 52:
Windows cannot verify the digital signature for the drivers required for this device. A recent hardware or software change might have installed a file that is signed incorrectly or damaged, or that might be malicious software from an unknown source. (Code 52)
С помощью встроенной утилиты sigverif.exe (File signature verification) можно вывести драйвера, для которых отсутствует цифровая подпись. Запустите утилиту, нажмите кнопку Start. Утилита просканирует хранилище драйверов Windows и выведет файлы драйверов без подписи.
Для работы устройства с неподписанным драйвером вам придется каждый раз загружать Windows с помощью клавиши
F7
, что неудобно.
Обратите внимание, что на компьютерах с UEFI и включенным режимом Secure Boot, отключить проверку подписи драйверов нельзя. Придется отключать Secure Boot в настройках BIOS (UEFI).
Отключить режим проверки подписи драйверов из командной строки Windows
Чтобы при каждой загрузки компьютера не выбирать режим загрузки с отключенной проверкой подписи драйверов, можно изменить настройки загрузчика Windows с помощью утилиты bcdedit.exe.
Откройте командную строку с правами администратора и выполните последовательно следующие команды:
bcdedit.exe -set loadoptions DISABLE_INTEGRITY_CHECKS
bcdedit.exe -set TESTSIGNING ON
bcdedit.exe -set NOINTEGRITYCHECKS ON
Перезагрузите Windows:
Shutdown -f -r -t 0
Теперь Windows будет всегда загружаться в тестовом режиме, в котором не выполняется проверка подписи драйверов. В этом случае в правом нижнем углу рабочего появится небольшая ватермарка с надписью Test Mode и названием версии и билда Windows.
Для отключения тестового режима нужно выполнить:
bcdedit.exe -set loadoptions ENABLE_INTEGRITY_CHECKS
bcdedit.exe -set TESTSIGNING OFF
bcdedit.exe -set NOINTEGRITYCHECKS OFF
Разрешить установку неподписанных драйверов через групповую политику
В редакторе локальной групповой политики Windows (gpedit.msc) есть отдельная опция, позволяющая игнорировать отсутствует подписи при установке драйвера. Этот параметр GPO работает только в Windows 7 и 8, но не применим к Windows 10 или 11.
Откройте консоль редактора локальной GPO и перейдите в раздел User Configuration->Administrative Templates-> System->Driver Installation (Конфигурация пользователя -> Административные шаблоны -> Система -> Установка драйвера).
Откройте настройки параметра Code Signing for Device Drivers (Цифровая подпись драйверов устройств). Включите параметр GPO и в настройках выберите Ignore (Пропустить).
Перезагрузите компьютер и попробуйте установить неподписанный драйвер.

FIX 5: Using SFC and DISM Commands
System File Checker and Deployment Image Servicing and Management are two command-line utility tools that scan for corrupt Windows files and then replace them with their working counterpart. The major difference between the two is whereas the SFC replaces the corrupt files with the working ones from the cached directory on your PC, DISM does so by downloading the working files from the online Microsoft servers. And as of now, we will be making use of both these tools to fix the underlying issue. Follow along.
- Right-click on the Start Menu and select Windows Terminal (Admin).
- Then click on the down arrow present next to the new tab icon and select Command Prompt from the list.
- Once the CMD window is opened, copy-paste the below command to open the SFC Tool:
sfc /scannow
- Once the SFC Scanning is complete, it’s time to use the DISM Tool. So copy-paste the below command:
DISM /Online /Cleanup-Image /RestoreHealth
- Once DISM finishes scanning, restart your PC and check out the results.
FIX 6: Disable Secure Boot
If none of the aforementioned methods spelled out success, then your last course of action should be to disable secure boot on your PC.

You might not be able to re-enable Secure Boot until you factory reset your PC. So only refer to our guide if you understand this risk: How to Disable Secure Boot in Windows 11.
