以下是自己手动方式

office 2019安装包哪儿下载

https://msdn.itellyou.cn/

下载这个文件Office Professional Plus 2019 (x86 and x64) - DVD (Chinese-Simplified)

，它是官方原版镜像文件

复制ed2k地址用迅雷下载。

零售版转换为批量授权版

KMS激活只适合批量授权版，如果是零售版的office安装包，需要转换。

把下面的文本写到txt文件里，把txt文件改成bat文件运行就能实现转换。

cmd窗口出现Retail to Volume License conversion finished就表示转换成功了。
