Adding the current directory to Windows path permanently

Question

I am trying to add the current directory (from a command-line) to Windows path permanently, but I am having serious problems implementing this.

Answer 1

Simple solution:

The syntax of setx is slightly different than the syntax of set.

With set, I would do:

set PATH=%PATH%;%cd%

With setx, I needed to do:

setx PATH "%cd"

The first argument specifies the name of the environment variable.

The second argument specifies the value to add to this variable.

The double-quotes are required for when the second argument contains spaces.

This might also be the case with set, by the way.
