一些Windows用户在^(Windows)Windows 11/10设备管理器^{(Device Manager)}或DXDiag中看到错误消息：

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)

在本文中，我们将向您展示如何借助一些简单的解决方案来修复错误。

Windows 无法验证数字签名（代码 52^{(Code 52)}）

这些是您可以采取的措施来修复Windows无法验证Windows 11/10上的数字签名（代码 52^{(Code 52)}） ：

1. 从供应商网站下载驱动程序
2. 删除 USB 上层过滤器^{(Remove USB Upper Filter)}和下层过滤器^{(Lower Filter)}条目
3. 禁用驱动程序签名^{(Driver Signature)}强制

让我们详细谈谈它们。

1]从供应商网站下载驱动程序^{(Download Driver)}

面临此错误的两个最常见原因是他们尝试从不受信任的站点安装驱动程序。因此，如果您从某个地方但供应商的站点安装了驱动程序，您可能会遇到此错误。您可能会遇到此问题的另一个原因是驱动程序文件是否损坏。

两种情况下的解决方案都是相同的。您只需从供应商的网站卸载驱动程序并重新安装即可。

要卸载驱动程序，您可以按照给定的步骤操作。

1. 从开始菜单启动 设备管理器 。^{(Device Manager )}
2. 右键单击^{(Right-click)}给您带来麻烦的驱动程序，然后选择 卸载设备。^{(Uninstall device.)}
3. 单击 卸载 ^{(Uninstall )}以确认操作。

现在，从供应商的网站重新安装它并检查问题是否已解决。

2]删除USB上过滤器和下过滤器条目^{( USB Upper Filter and Lower Filter entries)}

如果问题出在USB驱动程序上，请尝试通过^(USB)注册表编辑器^{(Registry Editor)}删除USB Upper和Lower Filer条目，看看问题是否已解决。

为此，请 从“ 开始”菜单 启动^{(Start Menu )}注册表编辑器 ^{(Registry Editor )}并导航到以下位置。

Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{36fc9e60-c465-11cf-8056-444553540000}

现在，寻找 Upper Filer 和 Lower Filer并删除它们。

如果您在提到的位置没有上过滤器^{(Upper Filter)}和下过滤器^{(Lower Filter)}，您可以跳过此步骤。

最后，重新启动计算机并检查问题是否已解决。

3]禁用驱动程序签名^{(Disable Driver Signature)}强制

如果没有任何效果，并且您想以任何形式或形式使用此驱动程序，请尝试禁用Integrity Check。禁用驱动程序签名强制^{(Disabling Driver Signature enforcement)} 将禁止Windows尝试验证驱动程序的数字签名和完整性。那么，让我们看看如何禁用它。

从开始菜单^{(Start Menu)}以管理员身份启动 命令提示符 ^{(Command Prompt )}，一一键入以下命令并同时按Enter。

bcdedit -set loadoptions DDISABLE_INTEGRITY_CHECKS

bcdedit -set TESTSIGNING ON

如果这不起作用，请尝试在提升的命令提示符^{(Elevated Command Prompt)}中运行另一组命令，看看它是否解决了问题。

bcdedit /deletevalue loadoptions

bcdedit -set TESTSIGNING OFF

现在，重新启动计算机并检查它是否解决了问题。

希望您能够使用这些解决方案修复驱动程序^(Driver)错误。

Windows cannot verify the digital signature (Code 52)

Some Windows users are seeing an error in Device Manager or DXDiag of Windows 11/10 that says:

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)

In this article, we are going to show you how to fix the error with the help of some simple solutions.

Windows cannot verify the digital signature (Code 52)

These are things you can do to fix Windows cannot verify the digital signature (Code 52) on Windows 11/10:

1. Download Driver from Vendor’s Site
2. Remove USB Upper Filter and Lower Filter entries
3. Disable Driver Signature enforcement

Let us talk about them in detail.

1] Download Driver from Vendor’s site

Two of the most common reasons why one faces this error is if they try to install the driver from an untrusted site. So, if you have installed the driver from somewhere but the vendor’s site you may face this error. Another reason why you may face this issue is if the driver files got corrupt.

The solution in both cases will be the same. You just have to uninstall the driver and reinstall it from Vendor’s website.

To uninstall the driver, you can follow the given steps.

1. Launch Device Manager from the Start Menu.
2. Right-click on the driver that’s giving you trouble and select Uninstall device.
3. Click Uninstall to confirm the action.

Now, reinstall it from Vendor’s website and check if the issue is fixed.

2] Remove USB Upper Filter and Lower Filter entries

If the problem is with USB drivers, try removing USB Upper and Lower Filer entries via Registry Editor and see if the issue is fixed.

To do that, launch Registry Editor from the Start Menu and navigate to the following location.

Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{36fc9e60-c465-11cf-8056-444553540000}

Now, look for Upper Filer and Lower Filer and delete both of them.

If you don’t have Upper Filter and Lower Filter at the mentioned location, you can skip this step.

Finally, restart your computer and check if the issue is fixed.

3] Disable Driver Signature enforcement

If nothing works and you want to use this driver in any shape or form, then try disabling Integrity Check. Disabling Driver Signature enforcement will forbid Windows from trying to verify the digital signature and integrity of the driver. So, let us see how to disable the same.

Launch Command Prompt as an administrator from the Start Menu, type the following commands one by one and hit Enter simultaneously.

bcdedit -set loadoptions DDISABLE_INTEGRITY_CHECKS

bcdedit -set TESTSIGNING ON

If this doesn’t work then try running another set of commands in Elevated Command Prompt and see if it fixes the issue.

bcdedit /deletevalue loadoptions

bcdedit -set TESTSIGNING OFF

Now, restart your computer and check if it fixes the issue.

Hopefully, you are able to fix the Driver error with these solutions.
