You hit an important point here. Teaching IT to 16 jear old children is very much like being an admin for a large corporation. Most of them have installed VMWare, VirtualBox, Hyper-V and pfSense, depending on the preference of the other teachers. Most first-graders don't know anything about networking, so I didn't want to add WSL to that. I used Cygwin. Worked perfectly until I started to teach Sendmail. Sendmail runs in unprivileged mode. This means that it starts as root, but then switches to a user with very few rights. Cygwin couldn't handle that at first, but I got it working. But then students couldn't uninstall Cygwin anymore because of changed file ownership in Windows. I had to install a second Cygwin to uninstall the first. With MinC I took extreme care to get all the different models of Access Control Lists that are used in Windows right.
