Batch file you can stick in C:\Windows or C:\Windows\System32 after setting paths in environment variables, which called will add those paths to PATH: using %ExamplePath% adds C:\Whatever;C:\Whatever2 to %PATH%

using.bat

REM Created by: http://github.com/tilkinsc
REM Use the -v or /v switch anywhere to see the command issued.

REM Adds supplied path to the %PATH% variable, supports multiple paths per variable
REM Usage: using %EnvVariable% [-v]

REM Example:
REM set examp=C:\Whatever;C:\Whatever2
REM using %examp% -v
REM echo %path%

REM And the output would be: Processing path with "using C:\Whatever;C:\Whatever2 -v"
REM And the path would be: C:\Whatever;C:\Whatever2;C:\;C:\Windows;C:\Windows\System32...
REM Note: They are added first because of how Windows searches along path
