DevCon classes命令

classes命令列出了所有设备安装程序类，包括系统上的设备不使用的类。 在本地和远程计算机上都可以使用。

  devcon [/m:\\computer] classes

参数

如果要在指定的远程机器上运行，使用/m参数，并且目标计算机的路径使用反斜杠”\”来标识。

注意 若要在远程计算机上运行 DevCon 命令，组策略设置必须允许即插即用服务在远程计算机上运行。 在运行 Windows Vista 和 Windows 7 的计算机上，默认情况下组策略禁止对服务的远程访问。 在运行 WDK 8.1 和 WDK 8 的计算机上，远程访问不可用。

备注

• /m参数必须位于类的操作名称之前。 否则，DevCon 将忽略 /m 参数，并在本地计算机上显示类，而不会返回语法错误。
• 在 DevCon 显示中，按 GUID) 的顺序列出类，按它们在 (注册表中的显示顺序列出。
• 若要在安装程序类中查找设备，请使用 DevCon ListClass 操作。 若要查找特定设备的安装类，请使用 DevCon Stack 操作。

用法示例

devcon classes > setupclasses.txt //将运行结果输出到setupclasses.txt文件中，如果文件不存在则创建
devcon /m:\\Server01 classes
