REM 1. Remove from Persistent User PATH via PowerShell
REM The paths are passed through the environment rather than interpolated
REM into the -Command string. A user directory containing an apostrophe --
REM C:\Users\O'Brien -- terminated the PowerShell single-quoted string early,
REM so everything after it was parsed as code: an installer that could be made
REM to run arbitrary PowerShell by naming a folder. $env: is data, not syntax.
