前言
Steam 安装游戏时会自动安装需要的运行库， 这点在 20 年前 Steam 还只是 CS 启动器，商城游戏数量还不如蒸汽平台， 各种下载站群魔乱舞的时候很实用，但放在今天就没什么意义。 况且 Steam 判断运行库安装的标准是「有没有通过 Steam 安装过」， 如果自己下载安装，但没有在 Steam 安装过，Steam 通通当作没有安装， 愉快地下载 CommonRedist 到本地，然后再提示系统已经安装了更新版本🙃， 浪费多余的带宽、硬盘和时间。
原理
Steam 安装 _CommonRedist 后在注册表会写入对应信息，以此判断运行库是否安装。
所以只要把运行库的信息提前写入注册表，即可避免重复安装。
提醒
运行库安装
下面 #注册表 提到的路径适用于 64 位 Windows 10/11 系统，
32 位对应位置为 HKEY_LOCAL_MACHINE\Software\Valve\Steam\Apps\CommonRedist。
这个方法只能阻止 Steam 自动安装运行库，请提前确保系统已经安装， 如果系统本身没有安装，游戏是无法运行的。
首选 vcredist，集成了常用的各种版本 .NET 和 Visual C++ 运行库， 不用在 M$ 那难用的各种跳转链接中找下载地址。
如果已经在使用 winget 或 Chocolatey/Scoop 等第三方软件包管理器，
搜索 vcredist 等关键词安装即可。附一个 winget 使用的命令，仅供参考：

注册表备份
同时由于需要操作注册表，导入前建议自行备份，出错了可以回退。
注册表
只推荐屏蔽 .NET、DirectX 和 vcredist 这烂大街的三大件，OpenAL/PhysX/XNA 引擎/运行库等在现代游戏中比较少见，安装包可能也不太好找，建议从 Steam 安装。
下面的是完整版，复制内容保存为 no-steam-commonredist.reg，（备份注册表）导入即可，其他分支版本可到 anti-steam-commondist 下载或基于完整版删减得到。
