正常情况下,我们在电脑里插入usb设备时，在电脑右下角托盘上，就会出现安全删除硬件的图标。但是当我们遇到usb设备接入后却没有显示安全删除硬件的情况该怎么做呢？让装机吧www.125315.com来教你吧。
安全删除硬件就是在USB设备与电脑确定没有进行数据交换的情况下，停止对USB设备的供电。如果不安全删除，直接拔出usb设备的话，就会对usb设备造成损伤，此时要有数据传输的话还会使数据损坏，所以安全删除硬件是很有必要的。
方法一：
在"运行"对话框中键入"devmgmt.msc"，回车打开设备治理器。在"磁盘驱动器"下找到"Generic Flash USB Device"选项。
鼠标右键单击"Generic Flash USB Device"，选择"属性"，打开属性窗口。然后打开策略标签页，选择"为提高性能而优化"，单击"确定"按钮。重新插拔一次USB设备，"安全删除硬件"图标应该出现了。
方法二：
单击"开始→运行"，在对话框中键入"C:\WINDOWS\system32\systray.exe"命令，回车执行，拔插一下USB设备，查看是否出现图标。
假如上面的步骤依然无法找回删除的u盘硬件图标。我们就继续打开"运行"对话框，键入"regedit"，回车打开注册表编辑器。依次展开如下注册表文件： [HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run]，右击它，新建一个字符串值命名为"systray.exe"，然后双击它，将它的数值改为"C:\WINDOWS\system32 \systray.exe"，确定注册表编辑器之后退出。
方法三：
在运行中，键入"SFC /scannow"，回车，系统会自动进行系统文件扫描，当提示到插入Windows安装光盘时将安装光盘插入到光驱，修复完成后，重新启动计算机即可。
方法四：
如果仍然不行，建议重新安装一下USB端口的驱动，不会重装usb端口驱动的可以直接采用重装主板驱动的方法来重装usb端口。
