Thanks. I use Windows at work, and had a similar set up with multiple versions of standalone Strawberry. Both Windows and Perl on Windows have grown on me other the years. Anyway, I sort of rolled my own simple version of perlbrew using a bat script to modify a symlink (Junctions) pointing to the "active" version of Perl.
like UnxUtils, gnuwin32 has made working on Windows much more enjoyable. I dabbled with the linux subsystem, but it's too inter-connected to windows binaries for me.
