Sounds like you need to familiarise yourself with PowerShell and Group Policy.

Vbox will create a bridge with my wifi card (I’m a laptop user with no option for a wired nic in the host).

I’ve never been able to get kvm to do that and haven’t found any working instructions online that a simpleton like me can follow

You can always try the ‘Contact’ form on the site, it’s not likely anyone here is going to be able to give you good advice

So what is your suggestion for a viable alternative that auditors will also accept?

I don’t have a better answer for OP, but telling them to switch distros is also not answering their question at all.

I would highly recommend against installing a pirated version of Windows like BearOfATime suggests (at least via the second link he provided) - it could cause trouble for both you and your school.
