电脑小白必看！轻松学会在CMD中启动未签名驱动程序的方法及注意事项

在电脑的使用过程中，我们经常会遇到需要安装或更新驱动程序的情况。有些时候，驱动程序可能没有经过官方认证，也就是所谓的“未签名”驱动程序。对于电脑小白来说，这可能是个棘手的问题。别担心，今天就来教大家如何在CMD中启动未签名驱动程序，并提醒一些注意事项。

第一步：了解未签名驱动程序

首先，我们要明白什么是未签名驱动程序。简单来说，未签名的驱动程序意味着它没有经过微软或其他官方机构的认证。虽然这可能会带来一些安全风险，但在某些情况下，我们可能需要使用这些驱动程序，比如兼容性问题。

第二步：开启CMD管理员权限

在尝试安装未签名驱动程序之前，我们需要以管理员身份打开CMD。以下是操作步骤：

1. 按下Win + R键，输入cmd并按回车。
2. 右键点击CMD窗口，选择“以管理员身份运行”。

第三步：安装未签名驱动程序

1. 在CMD窗口中，输入以下命令（假设你的驱动程序位于D:\驱动目录）：

D:

1. 切换到驱动程序所在的目录：

cd \驱动

1. 使用driverquery命令查看当前系统中的驱动程序列表：

driverquery

1. 找到需要安装的未签名驱动程序，并使用以下命令安装（以MyDriver为例）：

driverquery | findstr "MyDriver" > installed_drivers.txt

这条命令会查找名为“MyDriver”的驱动程序，并将结果输出到installed_drivers.txt文件中。

1. 使用以下命令安装未签名驱动程序：
