Disabling the driver signature enforcement windows 8

Установка неподписанного драйвера в Windows 8

Требование обязательного наличия цифровой подписи драйвера в Windows 8 (Device Driver Signing) –это требование системы безопасности Windows, которая разрешает установку только драйверов, имеющих цифровую подпись производителя. Система сертификации и подписывания драйверов нужна Microsft для того, чтобы максимально обезопасить систему от установки некорректного или опасного ПО, способного дестабилизировать систему.

При попытке установки в Windows 8 драйвера, не имеющего цифровой подписи появляется окно с предупреждением:

“Windows encountered a problem installing the driver software for your device. Windows found driver software for your device but encoutered an error while attempting to install it. The hash for the file is not present in the specified catalog file. The file is likely corrupt or the victim of tampering.”

(Хэш этого файла отсутствует в заданном файле каталога. Возможно файл поврежден или подделан)

Напомним, что требование обязательного подписывания драйверов, выполняемых в режиме ядра, появилось впервые в 64 битной Windows Vista. Однако, если в Windows 7 (ранее мы уже описывали как в Windows 7 можно отключить проверку цифровой подписи драйвера) и Vista, система еще предлагала возможность установки неподписанного драйвера (что не всегда получалось), то в Windows 8, установка драйвера без цифровой подписи просто завершается с соответствующим предупреждением.

Отключаем проверку цифровой подписи драйвера в параметрах загрузки Windows 8

Тот же самый эффект (попасть в режим настройки параметров загрузки системы) можно, перезагрузив компьютер из командной строки (запускать с правами администратора):

Далее нужно выбрать пункт Troubleshoot.

Troubleshoot win 8

Затем выберите опцию Advanced Startup

Далее выбираем Startup Settings

И, наконец, нажмите кнопку Restart

Компьютер опять перезагрузится и перед вами появится меню выбора опций загрузки. Нас интересует пункт Disable driver signature enforcement (отключить проверку драйвера), выберите его нажав на клавиатуре клавишу F7 или 7

В результате Windows 8 загрузится в режиме, в котором возможна установка подписанных драйверов. Теперь при установке такого драйвера (через диспетчер устройств или с помощью мастера) в Windows 8 появится окно с предупреждением системы безопасности Windows:

Windows can’t verify the publisher of this driver software

Выберите пункт: Install this driver software anyway, после чего драйвер должен установится. Осталось перезагрузиться в обычном режиме и проверить работоспособность установленного драйвера и устройства.

Установка неподписанного драйвера в Тестовом режиме Windows 8

В том случае если вышеприведенная методика у вас не сработала, существует еще один способ установки неподписанных драйверов. В Windows 8 и Windows Server 2012 существует так называемый «тестовый режим работы» (Test Mode), в котором возможна установка любых (в т.ч. и неподписанных драйверов).

Чем грозит работа системы в «тестовом режиме»? Технически вы работаете с той же самой полноценной ОС, но есть несколько нюансов. Во-первых, формально такая конфигурация не поддерживается вендором (Microsoft). Во-вторых, переведя систему в отладочный режим работы, вы существенно снижаете ее безопасность и стабильность работы ОС, так что риск появления различных ошибок, BSOD-ов и заражения ее существенно увеличивается.

Итак, на 64 битной ОС нужно запустить командную строку с правами администратора и последовательно выполнить команды:

Первую команду можно заменить на

После каждой команды должно появляется сообщение об ее успешном выполнении.

Затем перезагрузите систему и попробуйте установить неподписанный драйвер.

Факт работы Windows 8 в тестовом (отладочном) режиме проявляется в наличии в правом нижнем углу рабочего стола надписи: Тестовый режим (Test Mode), версии ОС и номера сборки Windows.

Чтобы отключить Test Mode, необходимо с правами админа выполнить команды:

Вместо первой команды можно использовать:

Итак, мы рассмотрели способы отключения проверки цифровой подписи в 64-битной версии Windows 8.

Стоит отметить, что подобная проблема наиболее часто возникает у владельцев всевозможных старых устройств (драйвера на которые также существенно устарели). Этим «счастливчикам» нужно быть готовым к тому, что старые драйвера без цифровой подписи производителя, установленные по данной статье в обход системы безопасности Windows, не всегда будут работать корректно. Поэтому в первую очередь рекомендуется проверить наличие свежей подписанной версии драйвера для Windows 8 (Windows 7) на сайте производителя.

Question

Does anyone know how to PERMANENTLY disabled driver signature enforcement in Windows 8.1?

I have an old piece of hardware that will never have signed drivers for 8.1. The driver installs and works just fine. I tested by going to advanced startup options, and choosing «7) Disable driver signature enforcement». The driver installs and works fine for one session. After reboot, the driver refuses to load because it isn’t signed.

The unsigned driver still fails to load after a reboot.

Please help, this is driving me bonkers!

Answers

Since a patch for Vista RTM, the option to PERMANENTLY disabled driver signature enforcement is removed. There are tools outside to workarond it:

But I have no idea if they still work in Win8.x

DSEO 1.3b did the trick for Windows 8.1. Since test signing was already enabled, I just had to «sign a system file» with DSEO.

I’ll also note that it seems possible to get the Windows 8.1 Driver Dev Kit and use makecert and signtool to accomplish the same thing, but DSEO is way easier.

I would also like to note that there are a few viruses out there that infect through driver files, and running a system full time in ‘test mode’ leaves the door open to them. In no way should a system be used in production with this workaround.

One more thing to note, re-enabling Secure Boot in the system BIOS disabled test mode, which caused the driver to stop working. I disabled Secure Boot, and tried to use DSEO to re-enable test mode, but it did not work. I had to run the follow two commands and reboot before it worked again:

I used this way and fixed.

rename problem files in C:\windows\system32\drivers\. and reinstall driver. I can’t post link here, see: en.community.dell.com/techcenter/os-applications/f/4457/t/19577823.aspx

DSEO 1.3b not working at win 8.1. yes u can sign the driver but u cant enable test mode and it make the driver cant working.

Top 2 Ways to Disable Driver Signature Enforcement on Windows 10/8.1/8/7/XP/Vista

How do I disable the driver signature enforcement in Windows 10? The driver signature enforcement error screen can’t be cleared… If you are going to turn off the driver signature enforcement feature on your 64 bit or 32 bit Windows 10, Windows 8.1, Windows 8, Windows 7, Windows XP or Windows Vista, you are in the right place. This post will tell you what it is, how to disable driver signature enforcement, how to enable it if needed and what should you do to enable all installed drivers work properly, also applied to Windows 10 Creators Update or Fall Creators Update 1709.

Part 1. What is Windows Driver Signature Enforcement

When you install drivers on your computer (from manufacturers, OEM, Windows Update or 3th-party driver download software, etc.), some of the drivers can work properly, while some may not. The working driver must be the signed driver that includes a digital signature, and the digital signature is an electronic security mark that can indicate the publisher for the driver, as well as all related information if someone has changed the original contents of the drive package. All drivers and system files must be digitally verified by Microsoft, and Windows won’t run the unsigned drivers on both 32-bit or 64-bit system. This is the «driver signature enforcement».

To increase security, Microsoft has introduced the driver signature enforcement in Windows OS, including Windows Vista, Windows XP, Windows 7, Windows 8, Windows 8.1, and Windows 10. This restricted feature has strict limitations on driver signing, especially in Windows 8, 8.1, and 10.

Windows will alert you if a driver is not signed or is not certificated with one of the messages like:

Windows can’t verify the publisher of this driver.

This driver has been altered.

Windows cannot install this driver.

Part 2. Why Do You Need to Disable Driver Signature Enforcement on Windows 10/8.1/8/7/XP/Vista

Many programs which use driver files do not have digital signature authentication, such as the phone drivers or other USB drivers. To receive verified certificates, manufacturers or developers have to pay Microsoft, and this makes lots of drivers are not accessible in Windows. To install the unsigned drivers on your computer and make them work properly, you need to disable driver signature enforcement.

Is it good to bypass or disable the driver digital signature enforcement? Installing unsigned drivers may have some risks, since the drivers can be modified or inserted something we don’t know. However, if you are sure the drivers you are going to install are safe, you can turn off this driver signature enforcement feature and install the unsigned drivers.

Part 3. How to Disable Driver Signature Enforcement Permanently – Top 2 Ways

How to Disable/Enable Driver Signature Enforcement in Windows 8 and 8.1

As we know, the price of computer hardwares is getting lower and lower. In order to use the more advanced configurations, an increasing number of people apply 4GB or 8GB RAM in their computers. Moreover, most people change their operating system to Windows 8.1 (64 bit), because 32 bit system cannot support memory which is more than 4GB. However, taking system security into consideration, the 64-bit version of Windows 8.1 limits the installation of uncertified drivers. Whereas, most small programs which use driver files do not have digital signature authentication, including phone drivers. Does it mean that we cannot use the drivers we applied before on the Windows 8.1 of 64 bit? No, we can solve the problem by disabling driver signature enforcement in Windows 8 and 8.1.
