It rather involved being on the other side of this airtight hatchway: Changing administrative settings
The blog post discusses the challenge of changing administrative settings when the action requires already having administrative access, likening it to being on the wrong side of an airtight hatchway and needing to unlock the door from the inside.
Background
- Raymond Chen writes *The Old New Thing*, a long-running Microsoft blog that explains Windows internals, historical design decisions, and quirks of software development, often with dry humor.
- This post’s title references a famous sci-fi/hacker trope: an "airtight hatchway" that can only be unlocked from the other side — a metaphor for a catch-22 in system design.
- The actual content of the post (about modifying Windows administrative settings) is minimal here, but the joke is that to change certain protected settings, you already need the very administrative privileges those settings control — a circular dependency that mirrors the "hatchway" paradox.
- The post would typically walk through a registry or Group Policy trick that lets an admin who is already inside the system (i.e., already has some access) change a setting that normally requires higher privileges, effectively "unlocking the door from the inside."
