If this sounds like your week
You changed your right-click menu weeks ago. What exactly did you do?
Customize the context menu over time — hiding entries, disabling handlers, promoting favorites — and the changes blur together. On a machine you're responsible for, "what changed the shell, and when?" is a real question, and most tools answer with a plain text log you simply have to trust.
Where tooling usually breaks
A log you can't verify is a log you can't rely on.
An ordinary log file can be edited, truncated, or quietly corrupted, and you'd never know. There's no built-in way in Windows to see a trustworthy, ordered record of what touched the context menu — so accountability comes down to memory.
