Retrieve System Path

HI all, i would like to run command which located inside windows folder, and in consideration for different user may install their windows in different kind of name, i know in command prompt we could type %SYSTEMROOT%\application.exe, but by implementing this string to Process.exec fail. return exit code = 2 (path not found or some kind).

Is there any class/method able to return the system/windows path?
