MySQL 8.4 Reference Manual Including MySQL NDB Cluster 8.4
          You must exercise great care when editing your system
          PATH by hand; accidental deletion or
          modification of any portion of the existing
          PATH value can leave you with a
          malfunctioning or even unusable system.
        
        To make it easier to invoke MySQL programs, you can add the path
        name of the MySQL bin directory to your
        Windows system PATH environment variable:
      
On the Windows desktop, right-click the My Computer icon, and select .
Next select the tab from the menu that appears, and click the button.
Under System Variables, select , and then click the button. The dialogue should appear.
            Place your cursor at the end of the text appearing in the
            space marked Variable Value. (Use the
            End key to ensure that your cursor is
            positioned at the very end of the text in this space.) Then
            enter the complete path name of your MySQL
            bin directory (for example,
            C:\Program Files\MySQL\MySQL Server
            8.4\bin)
          
There must be a semicolon separating this path from any values present in this field.
            Dismiss this dialogue, and each dialogue in turn, by
            clicking  until all of the
            dialogues that were opened have been dismissed. The new
            PATH value should now be available to any
            new command shell you open, allowing you to invoke any MySQL
            executable program by typing its name at the DOS prompt from
            any directory on the system, without having to supply the
            path. This includes the servers, the
            mysql client, and all MySQL command-line
            utilities such as mysqladmin and
            mysqldump.
          
        You should not add the MySQL bin directory
        to your Windows PATH if you are running
        multiple MySQL servers on the same machine.
