在某些时候，您可能需要查看安装在 Windows 10 或 Windows 11 PC 上的硬件驱动程序的状态。在设备管理器中，查看特定设备驱动程序的属性时，您可能会在设备^(Device)状态字段中看到消息“此设备的驱动程序已被阻止启动（代码 48） ”。^{(The driver for this device has been blocked from starting (Code 48))}这篇文章提供了有关如何最好地缓解此问题的建议。

完整的错误消息是这样读的；

The driver for this device has been blocked from starting because it is known to have problems with Windows. Contact the hardware vendor for a new driver. (Code 48)

这是出现在设备状态中的^(Device)设备管理器错误消息^{(Device Manager error message)}，表明当前安装的驱动程序存在严重问题，并且在您对 PC 进行了一些重大更改后发生错误。

此错误最可能的罪魁祸首包括：

• 内存完整性和驱动程序问题。
• 系统文件问题。
• 内存问题。

此设备的驱动程序已被阻止启动（代码 48^{(Code 48)}）

主要解决方案是安装兼容当前版本的Windows的驱动程序。您需要与OEM联系以了解是否有新的更新。如果没有，那么您可以尝试安装唯一具有兼容模式的驱动程序，看看问题是否为您解决。如果这也没有帮助，请尝试以下建议：

1. 运行 SFC 扫描
2. 更新硬件驱动程序
3. 在安全模式下安装驱动程序
4. 关闭内存完整性
5. 禁用 Hyper-V（如果适用）
6. 运行 Windows 内存诊断测试。

让我们看一下关于列出的每个解决方案所涉及的过程的描述。

1]运行SFC扫描

您可以采取的第一个措施来解决此设备的驱动程序已被阻止启动（代码 48）^{(The driver for this device has been blocked from starting (Code 48))}问题是运行 SFC 扫描- 因为该错误可能是由于系统文件损坏而触发的。

2]更新硬件驱动程序

正如错误描述中建议的，联系硬件供应商以获取新驱动程序，这只需要您更新引发此错误代码的硬件驱动程序。

您可以通过设备管理器手动^{(update your drivers manually)}更新驱动程序或通过命令提示符更新驱动程序^{(update the driver via Command Prompt)}，或者您可以在Windows 更新下^{(Windows Update)}的可选更新^{(get the driver updates on the Optional Updates)}部分获取驱动程序更新。您也可以从硬件制造商的网站下载最新版本的驱动程序。^{(download the latest version of the driver)}

3]在安全模式下安装驱动程序

此解决方案要求您启动 Windows 10/11 计算机进入安全模式^{(boot into Safe Mode)}，然后安装驱动程序^{(install the driver)}。

4]关闭内存完整性

此错误可能是由于内存完整性触发的，这是^{(Memory Integrity)}Windows 11/10核心^(Core)隔离的安全功能。该功能旨在防止攻击将恶意代码注入关键进程和设备驱动程序。

此解决方案要求您只需关闭内存完整性^{(turn off Memory Integrity)}并重新安装设备驱动程序。

5]禁用Hyper-V（如果适用）

一些受影响的 PC 用户报告说，禁用Hyper-V为他们解决了这个问题。因此，如果您不需要该功能，您可以禁用 Hyper-V^{(disable Hyper-V)}并查看问题是否已解决。

6]运行Windows内存诊断测试^{(Run Windows Memory Diagnostic Test)}

内存问题可能是导致错误的罪魁祸首。在这种情况下，请运行内存测试^{(run a memory test)}以检查RAM中的异常情况。如果发现，您需要更换受影响的RAM。

希望这可以帮助！

您如何解决此驱动程序已被阻止加载？

当您尝试安装或运行与您 PC 上运行的Windows 10/11的版本/构建不兼容的程序或软件时，您最有可能遇到错误消息此驱动程序已被阻止加载。^{(This driver has been blocked from loading)}要解决此问题，只需禁用 Driver Signature Enforcement^{(disable Driver Signature Enforcement)}。
