无限重置Navicat Premium 16的试用天数(方法二)

前情

本来平常项目里用用Navicat For Mysql就基本足够用了，但是看到金闪闪的Navicat Premium图标，本人的DNA就动了。。。

看这贵气又不俗气的logo，难道你就不心动？

立刻去下载了Navicat Premium 16，可是只能试用14天。。。嗯，小场面，关于注册激活，网上有很多大佬分享了，无论是破解工具还是替换DLL，多如繁星，这里咱就不一一赘述了。不过其中有个大佬的无限试用的方式，成功引起了我的注意，原文指路：体验Navicat Premium 16，无限重置试用14天方法(附源码)

根据大佬的方法，我在本地试了一下，还挺好用，感兴趣的小伙伴也学起来吧~

步骤

一、下载安装Navicat Premium 16

下载和安装的步骤很简单，点击下一步一直到完成安装就行了，附上官网下载链接：https://navicat.com.cn/products

二、清除注册表

这里可以选择手动或脚本自动清除注册表，在上面提到的大佬的原博里都有详述，这里转载一下便于以后查找：

1、手动清除

1）系统搜索"注册表编辑器"，找到以下位置HKEY_CURRENT_USER\SOFTWARE\Classes\CLSID\{F849765A-E477-BEAE-5962-032BC822FDD5}\Info

提醒一下：不同系统红色ID 可能不一样哦~！

直接将 Info 目录删除即可！

2）再在HKEY_CURRENT_USER\SOFTWARE\PremiumSoft\NavicatPremium中，删除Registration16XCS和Update文件夹中的文件。

2、脚本清除注册表

按照大佬提供的python脚本执行，并将它添加到了定时任务中。

搬运来的脚本如下：

import winreg
import os
import time
from collections import deque
from typing import Any
 
 
# root
HKEY_CURRENT_USER = winreg.HKEY_CURRENT_USER
 
# key path
PREMIUM_PATH = r'Software\PremiumSoft'
CLSID_PATH = r'Software\Classes\CLSID'
 
 
def get_sub_keys(root: Any, reg_path: str) -> list:
    """This function will retrieve a list of sub-keys under the path
    of `root` + `reg_path`.
 
    Args:
        root(Any): Root registry.
        reg_path(str): The relative specific path under the root registry.

    """
    key_result = winreg.OpenKeyEx(root, reg_path)

            sub_keys = winreg.EnumKey(key_result, i)
            sub_keys_list.append(sub_keys)
            i += 1
