To permanently turn off forced check of Windows driver signatures, you can enter bcdedit /set testsigning on and bcdedit /set nointegritychecks on through the command prompt and restart; or use the Group Policy Editor to set "Disabled Installation of Unsigned Drivers"; you can also temporarily bypass verification but require each reload; and you must turn off UEFI Secure Boot to ensure it takes effect.

To permanently turn off Windows' driver signature mandatory checking, it is actually an operation involving the underlying system settings. Simply put, Windows requires that all drivers must be digitally signed by default for security , but you may need to bypass this limitation in certain situations (such as test drivers, old hardware, or specific software).

Here are some feasible methods that apply to different versions of Windows (such as Win10/Win11), but please note: it is recommended to back up the system or create a restore point before operation.

Use the command prompt to disable driver signature mandatory

This is the most common and relatively simple method, suitable for users with certain hands-on ability.

• Open Command Prompt as administrator
• Enter the following command and press Enter:

   bcdedit /set testsigning on

• Then enter:

   bcdedit /set nointegritychecks on

• Finally restart the computer

After restarting, you will see a watermark of "Test Mode" in the lower right corner of the system, indicating that you have entered test mode and the unsigned driver can be loaded. This approach works in most cases, but in some systems it may still be impossible to completely bypass signature restrictions due to the integrity checking mechanism.

Turn off driver signature check using Group Policy Editor (Professional users only)

If you are using Windows Pro or Enterprise, you can use Group Policy to control driver signature behavior more granularly.

• Press Win R to open the run window and enter gpedit.msc
• Enter path:計算機管理> 管理模板> 系統(tǒng)> 設(shè)備安裝> 設(shè)備安裝限制
• Find the "Forbid installation of unsigned drivers" option and set it to "Disabled"

This method will not change the system startup parameters, nor will the Test Mode watermark be displayed, making it look "cleaner". However, it only affects the behavior of the device during installation and cannot completely prevent the system from checking signatures, especially in some systems with higher security levels, which have limited results.

Temporarily bypass signature verification using DSEO tools (not recommended for long-term use)

DSEO (Driver Signature Enforcement Overrider) is a third-party tool that can bypass signature checking at runtime and load unsigned drivers.

The steps for use are roughly as follows:

• Download DSEO Tools (requires searched by yourself)
• Run with administrator privileges
• Select "Disable Signature Enforcement"
• Then load the driver file you want to use

Although convenient, this type of tool has certain security risks, and it needs to be re-executeed after each restart. It is not recommended that ordinary users rely on it for a long time , especially in scenarios where system stability is high.

Special attention: The relationship between UEFI secure boot and driver signature

Even if you turn off driver signature mandatory by the above method, if Secure Boot is enabled on the motherboard, it may still prevent unsigned drivers from loading.

Solution:

• Enter BIOS settings
• Find the Secure Boot option and close it
• Save and exit

This step may be locked in some branded computers (such as Dell, HP) and requires administrator permissions or resetting the BIOS password to be modified.

Basically these are the methods. Each method has applicable scenarios, and you can choose the appropriate method according to your system version and technical level. Although the operation is not too complicated, it involves the system security mechanism. If you are not careful, it may lead to instability or even inability to start, so you must operate with caution.
