If, like me, you were wondering about this one, then this answer may help. https://superuser.com/questions/1334129/setting-an-environment-variable-in-windows-10-gpodder It's noted that any CMD variable set is only available while the CMD prompt window is open. After that point it is removed.

Selected Answer: B

The command "set.exe PATHEXT=d:\scripts" only sets the value of the PATHEXT environment variable to include the D:\Scripts folder. The correct answer is B. No. See related question 45 with the answer, explanation, and how-to.

B. No. The command "set.exe PATHEXT=d:\scripts" will set the value of the PATHEXT environment variable to "d:\scripts", but this is not the correct environment variable to modify for adding a directory to the system path. The PATHEXT environment variable is used to specify the file extensions that the command processor considers to be executable files.
