Before the "just install Linux" people show up - some things simply will not run on Linux.
Tools like this are great for a Windows VM for random Windows-only shit. Like Toyota Techstream.
Edit: I don't know why I'm getting downvoted for this. I literally have a copy of Techstream for my Toyotas, hosted in a Windows VM on my laptop that runs Linux. Techstream will only run under Windows. This is not up for debate.
