I agree that TMP and TEMP should go. PATH and PATHEXT might be
nice to jettison. PATH might be problematic and is probably overwritten
typically, so if it has to stay, that may not be a big deal. PATHEXT is
likely in the same boat as PATH though far less important. Everything
else looks to me like stuff that would be the same for all users anyway.
