    The Windows error once PATH passes 2047 characters

Once your PATH grows past 2047 characters, Windows' own dialog refuses to edit it. This tool reads and writes the registry directly, so length stops mattering.

  • View, add, edit, delete and reorder entries for both the User and System PATH.
  • Keeps references like %JAVA_HOME%\bin intact instead of expanding them.
  • Backs up and restores PATH configurations as JSON.
  • Checks for administrator rights before touching the System PATH.
