U盘病毒最近有抬头的趋势，有什么办法杜绝USB接口在电脑中直接运行呢？如果您使用的是Win7，那么通过组策略简简单单就可以实现禁止USB接口运行。一、打开控制面板-硬件和声音-设备管理器，在设备管理器中展开通用串行总线控制器列表，找到USB大容量存储设备，打开属性，在导航栏选择详细信息，复制出它的硬件ID，也保存记事本中。二、把自己经常使用的USB设备插入电脑中，设备进入正常运行状态后，打开控制面板硬件和声音设备和打印机，在此窗口中可看到所有设备。右击一个USB设备，选择属性，在打开窗口中选择硬件-属性，选择详细信息，选择硬件ID项，将其中的ID代码复制并保存到记事本中。三、打开运行对话框，输入gpedit.msc，这时会弹出组策略窗口，依次展开计算机配置-管理模板-系统-设备安装-设备安装限制，打开允许安装与下列设备ID相匹配的设备，在已启用点为实点，单击显示按钮，把之前保存在记事本里的设备ID粘贴进来。最后，再选择禁止安装未由其他策略设置描述的设备，在弹出的窗口中选择已启用，选择确定后退出。以上组策略设置，禁止USB接口运行，可以保证了Windows7系统的安全性，防止USB病毒的侵入而带来不必要的麻烦。and performance test copies of the record. If necessary, review should be carried out; 4) for spring hangers (included simple spring, hangers and constant support hangers) it should also be recognized as setting and locking of loads. 5) check the surface quality, folded layering and without cracks, rust and other defects. 5) after completion of the test and control drawing number one by one, by series baled. Color alloy steel parts, the parts marking installation location and rotation about the direction you want. 7.3.14. hangers installation 7.3.14.1 hanger layout a. a clear design of hanger should be installed strictly in accordance with the drawings and designs shall not be installed wrong, missing, etc. B. own arrangement of piping support and hanger set and selection should be based on comprehensive analysis of general layout of piping systems; cold installation of steam pipe with particular attention reserved for compensation of thermal expansion displacement and orientation. C. support systems should be rational to withstand pipe loads, static load and incidental load; reasonable piping displacement; guaranteed under various conditions, stress are within the allowed range. Strength, stiffness, and meet requirements to prevent vibration and soothing water, without affecting the adjacent equipment maintenance and other piping installation and expansion. D. equipment connected to the interface to meet pipeline thrust (torque) limit requirements; increase the stability of piping systems to prevent pipeline .
