REM PYTHON DETECTION
REM
REM Windows 11 always places the WindowsApps folder FIRST in the PATH.
REM This means "where python" returns the WindowsApps stub BEFORE any
REM real Python installation.  The old code took the first result and
REM hard-blocked - falsely flagging users who had uninstalled MS Store
REM Python (leaving behind the harmless WindowsApps stub) but also had
REM a proper python.org install further down the PATH.
REM
REM NEW APPROACH:
REM   1. Iterate ALL results from "where python"
REM   2. Skip any result that lives in WindowsApps (stubs / aliases)
REM   3. Skip any result that lives in a PythonSoftwareFoundation
REM      Packages folder (actual MS Store sandbox install)
REM   4. Accept the FIRST path that passes both checks as the real Python
REM   5. Launch key_finder.py using that ABSOLUTE path so the stub can
REM      never intercept it even after launch
REM -------------------------------------------------------------------------

set "REAL_PYTHON="

REM Collect every python.exe on PATH and pick the first non-stub one
for /f "delims=" %%i in ('where python 2^>nul') do (
    REM Skip WindowsApps stubs (these are App Execution Aliases, not real Python)

echo  The Microsoft Store version of Python runs inside a sandbox that
