【键盘】由于其配置信息(注册表中的)不完整或已损坏，Windows 无法启动这个硬件设备(代码 19)
解决这个问题的方法是：用鼠标打开注册表，找到HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E96B-E325-11CE-BFC1-08002BE10318}
将UpperFilters的值改为kbdclass
重启后，键盘就可以使用了。
或者导入下面的注册表也可以解决问题。Windows Registry Editor Version 5.00
"Class"="Keyboard"
"ClassDesc"="@%SystemRoot%\\System32\\SysClass.Dll,-3002"
@="Keyboards"
"Installer32"="SysClass.Dll,KeyboardClassInstaller"
