ROS2 command not found in Windows

edit

This is a repetition to my previous question

This time i am installing it on windows. I am following these instructions.

Problems : At first, i face this problem.

But my ros2 directory has all the folders (i fear some are missing).

Then I call the local_setup.bat file : call install\local_setup.bat.

When I try to run a demo node : ros2 run demo_nodes_py talker, it gives an error as ROS2 command not found.

Here is a screenshot of my path variables in the system variables.

EDIT : output of set.

    C:\WINDOWS\system32>cd C:\dev\ros2\

C:\dev\ros2>call install\local_setup.bat

C:\dev\ros2>ros2 run demo_nodes_py talker
