sublime3是一款很优秀的文本编辑器。软件免费，但是会经常弹出purchase的选项。解决方案如下：

一、修改host文件。可以写个脚本，也可以自己添加。

@echo off

SET NEWLINE=^& echo.

FIND /C /I "license.sublimehq.com" %WINDIR%\system32\drivers\etc\hosts
IF %ERRORLEVEL% NEQ 0 ECHO %NEWLINE%^127.0.0.1 license.sublimehq.com>>%WINDIR%\System32\drivers\etc\hosts

FIND /C /I "45.55.255.55" %WINDIR%\system32\drivers\etc\hosts
IF %ERRORLEVEL% NEQ 0 ECHO %NEWLINE%^127.0.0.1 45.55.255.55>>%WINDIR%\System32\drivers\etc\hosts

FIND /C /I "45.55.41.223" %WINDIR%\system32\drivers\etc\hosts
IF %ERRORLEVEL% NEQ 0 ECHO %NEWLINE%^127.0.0.1 45.55.41.223>>%WINDIR%\System32\drivers\etc\hosts

127.0.0.1 license.sublimehq.com
127.0.0.1 45.55.255.55
127.0.0.1 45.55.41.223

二、 打开sublime text 3，在上方“help工具栏”下面对应的”enter license”，输入以下代码：
