Adding a directory to the PATH environment variable in Windows

by

Option 1

After you change PATH with the GUI, close and re-open the console window.

This works because only programs started after the change will see the new PATH.

Option 2

This option only affects your current shell session, not the whole system. Execute this command in the command window you have open:

set PATH=%PATH%;C:\your\path\here\

This command appends C:\your\path\here\ to the current PATH. If your path includes spaces, you do NOT need to include quote marks.

Breaking it down:

  • set – A command that changes cmd’s environment variables only for the current cmd session; other programs and the system are unaffected.
  • PATH= – Signifies that PATH is the environment variable to be temporarily changed.
  • %PATH%;C:\your\path\here\ – The %PATH% part expands to the current value of PATH, and ;C:\your\path\here\ is then concatenated to it. This becomes the new PATH.
