qt使用wimlib-imagex，做windows系统备份还原

news 来源：原创 2024/5/10 6:35:34

wimlib-imagex是个第三方工具，可对系统映像进行操作，下载地址：
https://wimlib.net/downloads/index.html
在这里插入图片描述
程序主要用到以下这两个文件：libwim-15.dll和wimlib-imagex.exe

wimlib-imagex.exe的调用命令参数，可以通过cmd命令行wimlib-imagex --help进行查看，也可以自行百度。

系统备份：通过wimlib-imagex的capture命令，对指定系统盘进行捕获映像，生成wim文件。
系统还原：进入winPE系统，对指定系统盘进行格式化，再通过wimlib-imagex的apply命令，将之前备份的完整的wim文件应用到系统盘。

以下为涉及的部分参考代码：

SystemReloadObject.cpp
