PackageCompiler.jl’s [`create_sysimage()`](https://julialang.github.io/PackageCompiler.jl/dev/sysimages.html) is great for this! You can just swap out Julia’s default sysimage and have a fully-featured Julia session with whatever packages you need. Most packages nowadays are fully relocatable, and this should only require a single compilation, though packages with lazy-loading need to be specified manually. I’ve [written a tutorial on this](https://discourse.julialang.org/t/secure-systems-an-alternate-use-case-for-packagecompiler-jl/90955), and while I’ve never tried setting up a Windows environment this way, it seems possible, and this could be useful to others.
