Rapid Environment Editor (RapidEE) is an environment variables editor. It includes an easy to use GUI and replaces the small and inconvenient Windows edit box. RapidEE 8.x supports Windows XP, 2003, Vista, 2008, Windows 7, Windows 8 & Windows 10 (including 64-bit versions). If you still use Windows NT or 2000, then use version 6.1. For Windows 9x or ME use version 2.1.
