I'm not sure how this should best work on Windows (without symlinks, and where things generally work differently), but I would hope if this idea is more visible that someone more opinionated than I would propose the appropriate analog on Windows.

You'd probably have to just copy pythonv.exe to an appropriate directory, and have it use the configuration file to find the "real" prefix. At least, that'd be a relatively obvious way to do it, and it would have the advantage of being symmetrical across platforms: just copy or symlink pythonv, and make sure the real prefix is in your config file. (Windows does have "shortcuts" but I don't think that there's any way for a linked program to know which shortcut it was launched from.) No automatic way, but shortcuts can include parameters, not just the program name. So a parameter could be --prefix as was suggested in another response, but for a different reason.

Shortcuts don't work from the shell (well, cmd.exe, at least), do they? Can't test from here.
