I am just started learning golang on Windows 7.

go env
set GOARCH=amd64
set GOBIN=
set GOEXE=.exe
set GOHOSTARCH=amd64
set GOHOSTOS=windows
set GOOS=windows
set GOPATH=E:\Workbench\Go
set GORACE=
set GOROOT=C:\DevTools\Go
set GOTOOLDIR=C:\DevTools\Go\pkg\tool\windows_amd64
set CC=gcc
set GOGCCFLAGS=-m64 -mthreads -fmessage-length=0
set CXX=g++
set CGO_ENABLED=1
echo %envVar%
GOPATH
GOROOT

But others are not found.

So where are they stored? Some hidden configuration file?
