# ============================================================================
# Windows-specific uninstall helpers
# ============================================================================
#
# The installer (``scripts/install.ps1``) does four Windows-only things that
# ``remove_path_from_shell_configs`` / ``remove_wrapper_script`` don't cover:
#
#   1. Sets User-scope env vars ``HERMES_HOME`` and ``HERMES_GIT_BASH_PATH``
#      via ``[Environment]::SetEnvironmentVariable(..., "User")``.  These
#      don't live in ~/.bashrc — they're in the Windows registry at
#      HKCU\Environment.
#   2. Prepends to User-scope ``PATH`` (same registry location) entries
#      like ``%LOCALAPPDATA%\hermes\git\cmd``, ``%LOCALAPPDATA%\hermes\git\bin``,
#      ``%LOCALAPPDATA%\hermes\git\usr\bin``, ``%LOCALAPPDATA%\hermes\node``.
#      Again not in any rc file — only accessible via the registry or the
#      .NET [Environment] API.
#   3. Downloads PortableGit to ``%LOCALAPPDATA%\hermes\git\`` and Node to
#      ``%LOCALAPPDATA%\hermes\node\`` as user-scoped, isolated copies.
#      These are ~200MB combined and serve no purpose after uninstall.
#   4. On the ``hermes dashboard`` + gateway paths, drops files into
#      ``%LOCALAPPDATA%\hermes\gateway-service\`` and sometimes
#      ``%APPDATA%\Microsoft\Windows\Start Menu\Programs\Startup\`` — the
#      latter is handled by ``gateway_windows.uninstall()`` already.
#
# Running a PowerShell one-liner per operation is overkill and fragile on
# locked-down machines (Constrained Language Mode, restricted ExecutionPolicy).
# Direct registry writes via ``winreg`` work without spawning any subprocess
# and apply immediately for new shells (SendMessage WM_SETTINGCHANGE would
# be nicer but requires ctypes and buys us nothing — the user will log out
# or open a new terminal anyway).
