通过注册表修改键盘按键的映射。
参考文章 http://blog.chinaunix.net/uid-174325-id-3912617.html
具体操作方法：
将下面的文本存成“scancode.reg”，双击导入注册表。键值可通过查下面列出的键位表查询，找到要替换的 Scan Code码，把##,##替换掉就可以了。 （比如：用a(00 1E)替换1(00 4F)，这时先把a键的（00 1E ）反过来填充到前4个#号（1E 00），再把1键的(00 4F)反过来填充到后4个#号(4F 00)）
Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Keyboard Layout]
"Scancode Map"=hex:00,00,00,00,00,00,00,00,02,00,00,00,##,##,##,##,00,00,00,00
还原方法：
定位到注册表[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Keyboard Layout]，删除”Scancode Map”键值
