EnvMan
A Windows manager for user and system environment variables, with PATH editing, backups and undo.
About
A Windows environment variable manager drawn with MyGo's native UI. It shows user and system variables together with which overrides which, splits PATH and other multi-value variables into editable lists, and writes the registry directly rather than through setx, which truncates long values. Each save is backed up first for restore and undo; UAC is asked for only when saving system variables.
