1. 查找windows的键值对照表
从对照表中找到需要更改映射的按键的值，windows的键值对照表放在文末。
Caps Lock:3A 00
Esc:01 00
Backspace:0E 00
Insert:52 E0
2. 创建ScanCode Map
打开cmd或者powershell，然后输入“regedit”回车打开注册表编辑器找到以下路径：
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Keyboard Layout
右键新建名为“ScanCode Map”的“二进制值”
3. 修改ScanCode Map
修改时需要遵从ScanCode Map的规则：
（1）先填充8组00表示版本号和头部字节
（2）填充“xx 00 00 00”，其中"xx"代表映射数目
（3）按“目标字节码在前，源字节码在后”的原则继续填充
（4）最后填充4组00作为结束标志
我这里将Caps与Esc互换，将Insert变为Backspace。
4. 重启计算机生效
5. 取消设置
从注册表中删除创建的ScanCode Map这个键
