修改如下注册表项下的
InitialKeyboardIndicators的值为80000002，重启即可。
HKEY_USERS\.Default\Control Panel\Keyboard\
HKEY_CURRENT_USER\Control Panel\Keyboard\
代码如下
Windows Registry Editor Version 5.00
[HKEY_USERS\.DEFAULT\Control Panel\Keyboard]
"InitialKeyboardIndicators"="80000002"
[HKEY_CURRENT_USER\Control Panel\Keyboard]
"InitialKeyboardIndicators"="80000002"
如果还不行，参考
