Obscure #Windows question: After restarting explorer.exe, is there a way to force it to refresh environment variables from the registry? Or, a way to restart Explorer in a way that it picks up the latest ones from the registry on its own, rather than from when I last restarted the computer which was... ahem... December.
The answer is yes. Quit Explorer, run cmd from Task Manager, do a refreshenv command, then start Explorer from cmd instead of Task Manager. Will there be unintended side effects of starting my shell from a command prompt that is now closed? Who knows.
