I thought you accessed the Julia REPL (i.e., the terminal where you try using ... and ] add ...) by the Windows Shell (a.k.a. the command prompt). Now I believe you probably have an Icon or Menu Item that opens the Jullia terminal for you. I am not 100% sure how is the Julia installation in Windows, but I would assume that if you open the command prompt you can just type julia on it, and it will give you a Julia REPL as the one you are using. And if you type julia --compiled-modules=no it will give you a Julia REPL as the one you are using BUT that will not try to precompile the modules for you (I am kinda guessing it because the documentation for this flag is not great, but it will cause no harm anyway).
