A GUI app launched from Explorer inherits the environment block captured at login, so a HERMES_HOME set via 'setx' AFTER login is invisible in process.env even though the CLI (a fresh shell) sees it. The desktop then silently fell back to %LOCALAPPDATA%\hermes and reported 'No inference provider configured' despite a valid configured home (#45471). resolveHermesHome() now consults the live HKCU\Environment registry value on Windows before the LOCALAPPDATA default. New windows-user-env.cjs helper parses 'reg query' output, expands %VAR% refs, and fails safe (returns null off-Windows, on spawn error, or empty value). The registry value is normalized through the same normalizeHermesHomeRoot() path as the env var for consistency. Co-authored-by: jeffrobodie-glitch <jeffrobodie@gmail.com>
