Disabling driver signature in win 10. Verifying digital signature

Drivers are programs that serve link equipment with an operating system. Without this type of application, no installed devices won't work.

A digital signature of device drivers is a certificate that confirms the identity of the issuing person or corporation with additional information about the program. Thanks to this information, you can find the publisher and his contact information. Essentially, a digital signature is some guarantee of the security of the installed driver.

Purpose of the driver digital signature

It is important to understand that if the driver is not digitally signed (a pop-up window will tell you this), then most likely: it is not certified or the application is certified, but has been modified after the procedure. Both cases are very dangerous for the computer, since if you come across a version processed by a hacker (this may be a driver from a well-known company), then the application can perform absolutely any action on the computer. In fact, it is possible to catch a virus, and a dangerous one at that. Therefore, to continue with the installation, you must be confident in the program and its manufacturer.

By default, Windows checks the digital signature of drivers to determine how trusted the program is.

This procedure can protect against many computer problems due to possible counterfeits. Again, there is no guarantee that if you can install a digitally signed driver, you won't have problems with its contents.

Typically, drivers are supplied with the device, either on a hardware micro-media, such an application is installed automatically, or on a disk.

Sometimes such discs may contain a driver without a digital signature, but if the company that produced the product is trustworthy, you can install such a program.

Since according to Windows default will block the installation of the application, you will have to manually disable driver digital signature verification.

It is worth noting that you disable the check at your own peril and risk; in general, this is not recommended, but such a function still exists.

How to disable digital signature of drivers?

There are 4 options to achieve the desired result, let's start with the simplest. To use them, you will need administrator rights, because you will have to make changes to important settings systems.

Method 1

2.Then you should insert bcdedit.exe /set nointegritychecks ON in the window that opens, press enter.

Method 2

Similar to the previous one, also allows through command line disable the desired setting.

1.Press Win + R and enter the cmd command;

2.Now insert bcdedit.exe -set loadoptions DDISABLE_INTEGRITY_CHECKS;

3.When the test is complete, set the line bcdedit.exe -set TESTSIGNING ON.

Method 3

This method allows you to manually go through the Group Policy Editor and change required parameter settings, because it was its position that we changed through the console.

1.Press Win + R and paste gpedit.msc, then Enter;

2.In the window that opens, you need to follow the path User Configuration - Administrative Templates - System - Driver Installation;

3.Changing the digital signature of the driver is done by selecting the corresponding option in the right window and setting the value to “Disabled”.

Method 4

You can simply start the system without having to verify the driver's digital signature. When you have installed everything required applications, just run into normal mode. Windows won't verify the signature anymore installed drivers, but in the future it will work as before.

Restart your computer and go to special parameters downloads. This is done by pressing F8 when the system starts (usually at the moment the BIOS splash screen appears);
Select "Disconnect" mandatory verification driver signatures."

Then the computer will boot and you can easily install problematic driver. After completing all the steps, simply restart your computer.

Digitally signing a driver increases trust in the software and the product it comes with.

Also, not all users will understand how to install similar application. Therefore, most companies use certification centers and sign the driver.

Sometimes it happens that a person purchased a product from a well-known company, but the driver gives similar error. In this case, you should first try downloading required application from the manufacturer's official website, this is usually done without difficulty. Also for full-fledged work some equipment required additional programs, this is also worth taking into account.

Viewing the driver's digital signature

To view information about installed software you should:

Open the Start menu;
Click right click Go to “My Computer” and select the “Properties” option;
Next, in the menu on the left, click on “Device Manager”;

You will see a list of categories, select the one you need and expand it;
Right-click on the equipment with the signature you are interested in and select “Properties”;

Go to the “Details” tab;
You will see a drop-down list in the “Property” column. By selecting the desired option, information will be displayed in the value column.

The conclusion is simple, it is better to avoid drivers without a digital signature at all costs, because they are a pig in a poke. However, if there is no choice, of course you can install the software, but first try to research the manufacturer.

If you still have questions on the topic “Digital signature of Windows 7 driver”, you can ask them in the comments

As a rule, disabling driver signature verification in Windows 10 is necessary when the downloaded device driver does not have a digital signature confirming the security of the program. Driver signing ensures that the file comes from a trusted source and is not a virus.

Installing drivers without a digital signature is not always safe, but there are situations when it is the only way. For example, the driver may simply not have been tested for compatibility with your version of Windows. This article will teach you how to disable driver signing in Windows 10.

Disabling Windows 10 Driver Signature Verification One Time

This method allows you to disable driver signature verification one-time, until the next computer restart. That is, we disabled the verification, installed the driver, rebooted Windows and that’s it, the signature verification service is working again.

Click on the Start menu and go to Windows Settings (gear icon).

Go to the "Update and Security" section.

Go to the "Recovery" tab and in the " Special options download" click "Restart now".

Next, go to the “Download Options” item.

A menu will open with a choice of options Windows boot 10. Click on the item “Disable mandatory driver signature verification”.

You can either click on this point, or simply press the F7 key on your keyboard. After this, Windows 10 will boot without checking driver signatures, and you can safely install it. The next time you boot your computer, signature verification will work again.

Disable Windows 10 Driver Signature Verification Permanently

If there are three solutions, how can you disable driver signature verification forever.

Disable via Group Policy.

Disabling signature verification through the Group Policy Editor is only possible in Windows versions 10 Professional. If you have home version, then the method described in the next chapter of this article will suit you.

Launch the local group editor Windows policies 10. To do this, right-click on the start menu and left-click on “Run”. Or just press the Win+R key combination.

Write gpedit.msc in the window that opens and press OK or Enter.

In the Group Policy editor that opens, go to the following registry branches: “User Configuration” - “Administrative Templates” - “System” - “Driver Installation”. Double-click on the line on the right “Digital signature of device drivers.”

In this setting, you can choose two options in which you will solve your problem with driver signature verification. By default, the setting is “not configured”. If you enable the setting, then select the “skip” subsetting. In this case, if Windows detects a driver file without a digital signature, it will still allow you to install it. You can also explicitly select “disabled” and in this state the check will be disabled in principle.

Once you have changed the settings click “Apply” and “OK”. After restarting the computer, driver signature verification will not be performed. If you need to return driver signature verification again, you will have to return to this menu and select the setting status “enabled” and “block”.

Disabling via command line

Disabling driver signature verification via the command line has a limitation. This feature is only available if your computer is running BIOS. If you have UEFI, then you must first disable Secure Boot.

The procedure is as follows. Right-click on the Start menu and open Command Prompt as an administrator.

In the command prompt that opens, type the following command and press Enter.

bcdedit.exe -set loadoptions DISABLE_INTEGRITY_CHECKS

Now enter the second command and also press Enter.
bcdedit.exe -set TESTSIGNING ON

After the commands work (as in the screenshot above), restart your computer. Checking driver signatures will be disabled, but a sign about test mode will always hang in the lower right corner of the screen Windows operation 10.

To remove it, you will need to open a command prompt with administrator rights and type in next line:

bcdedit.exe -set TESTSIGNING OFF

Disable via Safe Mode and bcedit

This proven method is, in my opinion, the most convenient. Start your computer in safe mode.

Right-click on the Start menu and launch Command Prompt with administrator rights.

At the command prompt, enter the following line: bcdedit.exe /set nointegritychecks on and press Enter. Reboot your computer, after which signature verification will be disabled.

To enable the check again, perform the same operations, but enter the line bcdedit.exe /set nointegritychecks off.

Absolutely all operating systems Windows latest generations, the requirements for installed software have become extremely stringent, not only for application software, but also for control software. In particular, this applies to hardware drivers and virtual devices. The system constantly checks the so-called digital signature, which certifies the publisher (developer). On how to disable driver digital signature verification in Windows 7 or higher systems, further and we'll talk. But first, let’s dwell on what it is in general and why it is needed.

What is a digital signature and why are there problems with it?

Actually, the digital signature itself is nothing more than a certain mark, the presence of which indicates the legality of this software and him complete safety. In addition, such a signature indicates that this software has been certified according to international standards and is fully compatible with supported operating systems in which the corresponding system components that control the devices are expected to be installed.

However, the most basic reason why it is necessary to disable driver digital signature verification (Windows 7 is installed on the computer or more new system, not so important), lies in the fact that the main database of system drivers may not always contain control programs for non-standard devices or for equipment from manufacturers that are not on the support list, although their devices work just as well. In general, the picture turns out to be very sad: Windows does not see the signature and, when attempting to install, classifies the driver as potentially dangerous or unwanted software. Yes, of course, sometimes viruses can disguise themselves as such drivers, but if the user is absolutely sure that the driver is safe (for example, when downloading it from the equipment manufacturer’s website), then you will have to disable the digital signature verification of drivers (we’ll take Windows 7 as an example for now, although for other systems the proposed solutions are absolutely identical). Next, it is proposed to consider several basic techniques using the OS tools themselves or using third-party programs.

In principle, you can bypass such checks at the stage of driver installation. The operating system will usually display a message that the signature is missing, and the user should simply ignore this message and use the “Install Anyway” line. Naturally, Windows will start to “spit”, issuing warnings again and again. Again, you just need to ignore them, and in the end the necessary software will be installed (however, it is not a fact that the device will work correctly, since the system, due to its prohibitions and restrictions, can simply block the use of the installed driver). However, it is possible to combat such prejudices in Windows, and quite simply (fortunately, it itself is full of tools that allow you to disable these actions within a couple of minutes).

How to disable digital signature verification of Windows 7 drivers: methods

As for the basic techniques that are used to perform actions of this kind, the following are considered the most basic and effective:

disabling scanning at system boot;
changing group policy settings;
editing registry keys (almost the same as the previous item, but with higher priority);
using the command line;
substitution of signatures using special utilities.

How to disable driver digital signature verification when the system boots?

So let's start with the simplest technique. In Windows 7, you can disable driver digital signature verification at the boot stage. But for this you will need to call a special boot menu by pressing the F8 key at the start (as many do to enter the mode secure boot or to restore the system).

Here you simply select the appropriate line, after which the system is restarted in normal mode. Next you can install the required driver, using either the installer, or sections of the “Device Manager”, or automated programs to install driver updates.

Using Group Policy Management

No less effective is the method that allows you to disable driver digital signature verification in Windows 8.1 and Windows 10 (or the seventh version) in the Group Policy settings and permissions editor. It’s worth saying right away that all the actions described below are best performed under account administrator so that access to some sections is not blocked.

The editor itself is called from the Run console by entering the line gpedit.msc. You can disable driver digital signature verification using Group Policy and using the following sections through the user configuration with further selection of administrative templates, then through the system section and driver installation.

In the last section on the right in the editor window there is a parameter, the same signature line, on which you need to double-click or call the editing window through the RMB menu.

To install required configuration there are two ways:

complete shutdown services (activation of the “Disabled” line);
enabled mode with the ignore option set if the system detects an unsigned driver.

Both solutions are absolutely equivalent, although ideally it is better to use the first option, since when using the second solution, for some types of programs a corresponding notification may still be issued, which can, to put it mildly, be incredibly annoying. Then all that remains is to save the changes made and perform a complete reboot.

System registry manipulation

Similar to the steps described above in Windows 7, you can also disable driver digital signature verification through the registry editor. In principle, this is a kind of duplication of setting parameters in group policies, but changing registry keys has more high priority. In other words, if you change settings in group policies, you can change them in the registry. But once the settings have been configured in the registry, it will be impossible to change them in group policies.

So, first, the editor is called on behalf of the administrator (regedit in the “Run” console), after which in the HKLM branch, through the SOFTWARE and Policies directories, the section tree is navigated to the Driver Signing directory. On the right, you need to edit the BehaviorOnFailedVerify key, giving it a value of 0. If there is no such entry, you will need to create the DWORD key yourself.

There is no need to save changes (this happens automatically). After exiting the editor, as in all other cases, a reboot is performed.

Disabling a service from the command line: method one

In Windows 7, you can also disable driver digital signature verification through the command console launched with administrator rights. There are two main methods used for this.

The first option is to enter the combination shown above in the console, wait for the message about the successful completion of the operation to appear, exit the console and reboot.

Using the Shell: Method Two

The second method is almost similar to the first, only the combinations shown in the picture below are entered on the command line.

Next, as usual, comes a restart. The method may seem somewhat inconvenient due to entering not one, but two commands, however, such a solution cannot be discounted, because in in this case all are considered available options actions.

Using third party utilities

Finally, in Windows 7, you can try to disable driver digital signature verification using various types of programs that allow you to either disable system functions OS, or simply replace the signatures with valid ones.

As the most simple utilities programs with a common name are suitable Windows Manager, released for versions from seventh to tenth inclusive. As for substitution, you can use other applications. But the problem is that the driver can be installed, but after uninstalling the utility itself, it will crash automatically. So you should not rely on such application programs. A driver crash in such a situation can even lead to the system not just freezing or displaying some kind of message about problems that have arisen. But it’s not even possible appearance of BSoD, as a result of which problems will have to be solved at a different level. The solutions here are quite simple, but, as they say, it’s better not to take risks.

Actions with Windows Defender for the tenth modification

In Windows 10, one of the options for the above actions is to completely disable Windows services Defender, if active. Please note that such actions are not required if the system has any other antivirus package(in this case, “Defender” is blocked automatically).

Disabling the “native” component is done through the parameters menu by selecting the system partition, where to Windows options Defender switches off cloud protection and real-time protection.

Here, in fact, are all the main solutions, which are completely equivalent to each other, unless you take into account the actions to disable the Defender toolkit in Windows 10. However, as already mentioned, with the active state installed antivirus such actions are not required.

Yes, and here's another thing. If for some reason all the described actions do not give the desired result or their implementation turns out to be impossible due to too strong restrictions on the part of the so-called super administrator, try reducing the level of control of UAC “accounts” (access to this section can be obtained by typing the required abbreviation into the search field) or try to do all this using download to Safe Mode. In some cases, this approach may be the only the right decision. But in most cases, even with installed options by default, such actions are not required (they are only needed when the security settings have changed dramatically).

However, finally, it is worth reminding all users without exception that it is recommended to disable checks only in cases where it is known for sure that the software was downloaded from a trustworthy resource and does not contain explicit or implicit threats to performance operating system(for example, when downloading from the website of the device manufacturer or driver developer).

As a last resort, to ensure security after downloading, files should be checked for viruses with any available scanner (preferably portable type, independent of the installed standard means protection). Utilities like KVRT or Dr.Web CureIt!, which are capable of identifying almost everything, are perfect for these purposes. known threats And malicious codes, without requiring installation on hard drive, which can provoke conflicts with the standard antivirus at the software level.

The digital signature of the driver is used by Microsoft to identify the manufacturer and confirm that the product meets the requirements of the operating system. The presence of such electronic certificate guarantees that it will not be modified after release. Thus, the user receives a double guarantee of security and can be confident in the functionality of the resulting driver.

Windows checks the digital certificate automatically. Having detected its absence, the system issues a warning to the user about the danger of installation unsigned driver. To check components already installed in the OS, you can use built-in tools.

Direct X

Multimedia drivers are the most frequently updated OS components. You can check them for a certificate using the built-in diagnostic tool. We launch it with the command shown in the screenshot.

On the main tab, check the marked box. So we will include automatic check certificate of conformity utility.

Switching to the next tab, in the “Drivers” field we see a positive response from the system.

We check the remaining pages in the same way, making sure that there is a WHQL certificate.

Signature Verification

You can detect the presence of all components in the system without a digital signature using special utility checks. Let’s launch it by typing “sigverif” in the text field.

Click the marked button to activate the component testing procedure.

Completing verification will slightly change the appearance of the main utility window. Click on the highlighted button to open additional options.

Select the “View Log” option.

IN text editor A report on the status of the drivers installed in the system is launched. The designated “Status” column provides information about the presence of a WHQL digital certificate.

Having dealt with the current state of the system, let's look at how to disable driver digital signature verification in Windows 10.

Disable signature

While maintaining OS stability, Microsoft does not recommend installing components that do not have WHQL certificates, but this option remains in the system. The need to install an unsigned driver may arise due to various reasons. For example, this may be equipment that has been discontinued but is necessary for operation.

Group Policy

The easiest way to disable electronic signature is to change the security policy. We launch the editor using the “Run” menu.

In the main window, we sequentially expand the underlined items in the navigation area. Last section contains three parameters. The one we need is highlighted with a frame. Open it for editing.

In the control unit, set the switch to the “On” position. In the parameters area we use the drop-down menu. Select the item marked “2”. Apply and save the changes made.

The specified rule should take effect without a reboot.

Special boot options

The next method involves using special operating system boot options. Open the menu Windows settings and go to the section indicated in the screenshot.

In the navigation area, move to the “Recovery” item. Use the marked button to reboot the system.

Mouse control is available here, so we begin to move through the menu one by one. Open the troubleshooting section.

Select additional options.

Let's move on to the download settings.

This area is informational and only the marked button works in it.

The system goes into mode low resolution screen and disables mouse control. The item we need is seventh on the list. Select it by clicking control key"F7" in top row keyboards.

The computer will reboot, after which installation of unsigned drivers in the OS will become available.

Command line mode

Using this method, you can also disable driver digital signature verification in Windows 7. Launch PowerShell in elevated mode. Enter the commands shown in the screenshot sequentially.

After a reboot, the system will not report that it requires a digitally signed driver. To disable the mode, in the text of the last command we indicate “OFF” instead of “ON”.

Another option to use the command line requires rebooting into safe mode. We have already considered the sequence of actions. Having reached the additional parameters, select the indicated item.

The operating system will reboot again, displaying the Command Prompt in Administrator mode. Enter the command shown in the screenshot. To exit to graphic menu type “exit”.

Shutdown this mode also performed by replacing “ON” with “OFF” at the end of the control command.

Creating a Digital Signature

In some cases, the methods described may not help. When signature verification is not disabled Windows drivers 7 or 10, you will have to sign it yourself. For this purpose, we will need to unpack the installation package and find the file with INF extension. It contains the information necessary for installation in the system. Having found required file, call its properties and go to the “Security” tab. Copy the path specified in the “Object name” field.

Launch PowerShell with elevated rights. Enter the following command: “pnputil -a C:\path\name.inf”. We replace the line “C:\path\name.inf” with the copied path to the file.

As a result of its execution, the selected driver will be registered in the system. This same one the method will work and in the case when the digital signature of the driver constantly fails.

In conclusion

As we have seen, there are several installation options necessary components without electronic WHQL certificate. The steps are simple and can be performed by any user. However, installing an unsigned driver should not be the norm. Since it has not been tested by Microsoft, the company will not be held responsible for the consequences of installing it, and the user has a high chance of encountering BSOD errors.

Most of the problems of users who are faced with the fact that Windows OS cannot detect the device is due to the fact that starting from Windows 7 and up to new version Windows 10 has driver digital signature verification enabled. How to bypass this obstacle and install the required driver, read in this material!

What is a signed driver?

A signed driver is a device driver with a digital signature. A digital signature is an electronic security mark indicating the publisher of the software and changes to the original content software package drivers. If the driver is signed by the publisher and verified by a certificate authority, you can be confident that the driver was released by that publisher and has not been modified.

Windows will display one of the following warnings: the driver is not signed, the publisher's signature is not verified by a certificate authority, or the driver has changed since release. MicroSoft

In short, if the driver was not signed by MicroSoft, then such a driver will not have a digital driver signature for Windows. It is with such a driver that problems arise during installation.

In this article we will look at how to disable driver digital signature verification in Windows 10, Windows 8 and 8.1, as well as Windows 7.
