将capslock键替换为ctrl:

参考http://hushicai.com/2016/01/07/win7-jiang-CapsLock-ying-she-wei-Ctrl.html

新建caps_lock_to_ctrl.reg文件，内容如下：
Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Keyboard Layout]
"Scancode Map"=hex:00,00,00,00,00,00,00,00,02,00,00,00,1D,00,3A,00,00,00,00,00

运行后重启，完成。

交换左win键和左alt键：

将capslock键替换为左ctrl，同时交换win键和左alt键：
"Scancode Map"=hex:00,00,00,00,00,00,00,00,03,00,00,00,1D,00,3A,00,5B,E0,38,00,38,00,5B,E0
