为什么存在 Windows 注册表? [英] Why does the Windows registry exist?

问题描述

这是比直接编程更多的操作系统架构问题，但仍然如此.为什么 Windows 注册表被创建为一个完全独立的子系统来存储系统/应用程序设置?在 *nix 操作系统中有/etc 目录，这是完全可以理解的，因为文件系统是存储设置的自然分层方式，而微软决定创建一个完全外部的分层子系统，这似乎是一项愚蠢的投资，为什么不他们只是使用文件系统层次结构?

this is more OS architecture question than programming directly, but still. Why was the Windows registry created as a completely separate subsystem for storing system/application settings? In *nix OS'es there is /etc directory which is perfectly understandable, as filesystem is a natural hierarchical way for storing settings, while Microsoft decided to create a completely outside hierarchical subsystem, which seems to be a foolish investment, why didn't they just use a filesystem hierarchy?
